kelly hose drilling definition made in china

A rotary hose is also used as a means of permitting the kelly to be either raised or lowered through the drilling process while also allowing the drill bit to be raised with the drillstring. For this reason, it is also often referred to as a “kelly hose.”

Rotary hoses also function during the process that allows the drilling fluid to be pumped through the hose when the bit and drillstring are raised and lowered. This process is imperative in the completion of the drilling process.

These rotary vibrator hoses are made up of the Gates range of Black Gold hoses that meet the severe demands of today’s drilling methods including directional drilling, pressure pulses and elevated temperatures.

Flexible drilling rubber hoses play an important role in petroleum extraction. They should suffer high operating pressure, extreme operating temperature, abrasion and other inferior elements. Our special compounded synthetic rubber has been proven an effective and economical way to reject these problems. All our oilfield drill hoses are manufactured as API 7K or other related specifications.

Steel cable reinforcement loads most working pressure up to 15,000psi. The wires are usually zinc-plating or copper platting to improve steel wire resistant against rust and corrosion. Due to the thick reinforcement, the hoses should be handled or stored in correct way to avoid kicking or crushing. They will substantially decrease their rated operating pressure.

Rotary hose, Kelly hose, cement hose, mud hose, jumper hose and vibrator hose and choke & kill hoses are the most popular oilfield rubber hoses. They convey high-pressure drilling fluid from one place to another. Many end fittings are provided to satisfy different applications. Most end fittings are made according to API standards. Special order is also available.

Our drilling hoses are equipped with API end fittings – flanges, NPT threads and butt-weld unions to meet requirements on the market. Bespoke end fittings are also available.

A large-diameter (3- to 5-in inside diameter), high-pressure flexible line used to connect the standpipe to the swivel. This flexible piping arrangement permits the kelly (and, in turn, the drillstring and bit) to be raised or lowered while drilling fluid is pumped through the drillstring. The simultaneous lowering of the drillstring while pumping fluid is critical to the drilling operation.

The main advantage of a rotary drilling hose vibrator hose is that it helps you move water from one point to another without much struggle. Hose pipes are also versatile and can be used for various activities in your home or at your workplace. Moreover, rubber horse pipes are durable since rubber is a strong material. This means that you won’t need to replace it often. Additionally, rubber hoses are less prone to cuts and abrasions. Another advantage of this hose pipe is that it absorbs shocks and vibrations. Also, there is no need for specialized bending or brazing since it can bend easily. Lastly, it reduces pressure surges and lubricates itself.

When buying a rotary drilling hose vibrator hose, there are several factors that you need to consider, including length, couplings, thickness, and price. The length of the rotary drilling hose vibrator hose is an important factor to consider. If you are taking the water to the furthest corner of your compound, consider getting a longer pipe for convenience. Also, if you are watering a large garden, a longer pipe will serve you better. Couplings or horse pipe fittings are also another important consideration. These are the accessories that help you connect your pipe to the water source. They can either be made from brass or plastic. Some people prefer plastic couplings since they are lightweight, but they can break easily. Brass fittings are heavier but long-lasting. Lastly, consider the thickness of the pipe. This refers to the number of layers used to make the rotary drilling hose vibrator hose. Thickness determines the weight of the pipe and ease of bending.

Of course, those do still exist. And they have their place too, in situations where you might need something that tough. We recommend one made from the traditional rubber, in fact, as well as the best in class for other situations.

Many people who have used a Flexilla garden hose swear it’s the greatest ever made. It also does well in expert testing, where it lives up to its kink-free claims.

The manufacturer says the material is lead-free and drinking water safe, although it’s not tested or certified by any of the agencies that verify those claims. They also say it can withstand temperatures from -40 to 150°F, and owners attest that it holds up well in hot temperatures.

Need a tough garden hose for washing your car, for powering a pressure washer, or that can live outside during the worst winters? Then the Craftsman Premium offering should be at the top of your list.

This is a popular pick for landscape professionals and those who need something that can stand up to light commercial applications, such as mixing cement.

This product is as durable as they come. We saw a number of comments from owners who ran theirs over with their car (accidentally, of course) and reported that the couplings didn’t crush, and the hose was oblivious.

If you’re looking for something that’s a little easier on the wallet, but still easy to wrangle in a small garden, we recommend the Gatorhyde Coiled Garden Hose.

This setup includes the reel, a 9/16-inch diameter, 82-foot hose with a seven function nozzle, and a 6.5-foot leader hose. Many owners like that 82-foot length, saying it’s a nice alternative to having to choose between that standard 50 or 100 feet.

The Hoselink is intended to be wall-mounted and, when mounted, the reel can swivel 180 degrees. You will need a drill for the installation, so keep that in mind.

Users say the reel is easy to install and use, and the hose retracts very easily with the automatic rewind. Many also note that they’ve had one for several years and it is holding up well. The whole setup weighs 30 pounds.

The hose and reel are made from PVC and polypropylene with brass couplers, and stainless steel and plastic fittings. It is not food grade, so it’s probably best to avoid filling the dog’s bowl with this one.

The hose in integral to the reel and cannot be replaced. One nice feature is that the reel keeps the hose protected even in extreme weather conditions.

It’s not as sturdy as a traditional model, and some users complain of leakage and deterioration. However, the latter issue seemed to be more of a problem when the hose was left out continually, rather than rolling it up and storing it after each use.

Ideal for watering delicate new grasses or long, narrow areas like the side of a house, the Gilmour Vinyl Sprinkler Hose is a very versatile choice that can also function as a soaker. Just position it with the white side up for sprinkling, and the white side down for soaking.

The fittings are nickel plated. It measures the standard 5/8 inch in diameter. It only comes in a 50-foot length, but you can attach up to three hoses. Gilmour offers a lifetime warranty.

Subsequent to writing that article I happened to read an excellent book with the title Salt: A World History, written by Mark Kurlansky. I highly recommend it to anyone with an interest in history and human affairs, along with Kurlansky’s other books, Cod: A Biography of the Fish that Changed the World, and The Basque History of the World. The three books’ themes are interrelated in a most entertaining way. But to get back to Salt, in one chapter an ancient salt producing industry involving sophisticated drilling techniques and coproduction of brine and natural gas in China’s Sichuan province, far pre-dating western efforts, is detailed. I was tremendously interested by this, and immediately felt that this topic would make a great follow up to my first one, as it involved hydrocarbon exploitation, and better still, was ideal nourishment for the bee in my bonnet – it involved another culture, from long ago, whose exploits and achievements are frequently overlooked by us in the west.

Naturally, with such attractive conditions for human habitation, Sichuan has been occupied by humans since the early dawn of our existence. The countryside has been worked by the human hand for so long, that it is hard to spot a single wild area in the basin proper. Even steep hillsides are terraced for farming, and ancient family crypts hewn into rock cliff outcrops can be spotted frequently from the highway. The contrast between the luxury cars speeding along the modern 6-lane highways, and the ancient terraces, tombs and irrigation systems is startling, but one can easily imagine one long continuous evolution of human technology here, from thousands and thousands of years ago, to the present. Many of China’s ancient technical accomplishments came from this region, including sophisticated irrigation techniques, and what I am particularly interested in, their drilling technology.

The earliest evidence of wells in China, in Zhejiang Province, comes from the era when humans were first turning to agriculture in this region, some 7,000 years ago. Approximately 5,000 years ago Chinese coastal people were boiling sea water to produce salt. As high density human settlement penetrated further and further inland and increasingly relied on farming, salt, critical to human survival as a vital food supplement and preservative, became a valuable commodity. The first recorded salt well in China was dug in Sichuan Province, around 2,250 years ago. This was the first time water well technology was applied successfully to the exploitation of salt, and marked the beginning of Sichuan’s salt drilling industry. From that point on, wells in Sichuan have penetrated the earth to tap into brine aquifers, essentially ground water with a salinity of over 50g/l. The water is then evaporated using a heat source, leaving the salt behind.

At some point around 2,000 years ago the leap from hand and shovel dug wells to percussively drilled ones was made (figure 4). By the beginning of the 3rd century AD, wells were being drilled up to 140m deep. The drilling technique used can still be seen in China today, when rural farmers drill water wells. The drill bit is made of iron, the pipe bamboo. The rig is constructed from bamboo; one or more men stands on a wooden plank lever, much like a seesaw, and this lifts up the drill stem a metre or so. The pipe is allowed to drop, and the drill bit crashes down into the rock, pulverizing it. Inch by inch, month by month, the drilling slowly progresses. It has been speculated that percussive drilling was derived from the pounding of rice into rice flour. When I read of this technique in Salt, I imagined a fairly crude technology. I had no idea how sophisticated these drilling methods became, to the point where these people really had developed most of the tools and techniques one might see on a modern drilling rig, albeit on a smaller scale and without the benefits of modern machining methods.

At regular intervals in the drilling, the crushed rock and mud at the bottom of the hole needed to be removed. The drill stem would be pulled from the hole using a large wheel, somewhat similar in appearance to that on a modern flexible cable down hole tool truck. A length of hollow bamboo with a leather foot valve would then be lowered to the bottom of the hole. When the tube was lifted, the weight of the mud inside would keep the valve closed, and the contents could be brought to the surface. Drilling would then recommence.

The drilling method on its own is impressive, especially when considering that the rest of the world had nothing comparable in the earlier centuries. But even more impressive are all the techniques the Sichuan drillers developed to overcome common drilling problems – cave ins, lost tools, deviated wells, and so on (figures 5 & 6). A huge variety of tools and techniques evolved to handle well repair issues (figure 7). Many different drill bits were also developed, with different sizes, shapes and compositions, to deal with the different rock types encountered, and the many different drilling requirements. For example, opening the hole at the wellhead required a large heavy bit (3m long, 150-250 Kg) called the “Fish Tail” (figure 8); the “Silver Ingot” drilled the well bore rapidly, but roughly; the “Horseshoe” bit drilled slowly, but achieved round, smooth, high quality well bores. Hollow logs were used in the near surface as casing.

The fuel used initially in the evaporation process was of course wood. Sources of wood became scarce due to the scale of the salt production industry. Some energy saving techniques were used during evaporation: spreading the brine on tree branches under the sun to increase the salt concentration before boiling, and putting several boiling pans on the same chimney path to use residual heat. There are instances of oil and gas production and use in China going back as far as 61 BC, but it appears as if the salt and hydrocarbon industries were separate for a long time. Fortuitously, at some point in the 16th century, techniques to harness the natural gas encountered during drilling for brine were developed, and this allowed natural gas to be burned beneath the big salt pans. It was the coexistence of brine and gas that pushed Zigong’s salt production into the industrial scale. Once wells were able to reach down to 700-800m, they were able to produce both brine and gas from the Jialingjiang group Triassic formations. Annual salt production in Zigong in the 1850s was about 150,000 tons. The Chinese population was about 0.45 billion at that time. The salt industry was a huge economic driver, and many large cities in Sichuan were established, and flourished, because of the lucrative salt trade.

A key technological advance was the introduction of the “Kang Pen” drum at the end of the 18th century (figure 13). This drum sat on top of the wellhead, and the pressure within the drum was controlled such that gas and brine could simultaneously be produced, and efficiently separated. One bamboo pipe line would take away the brine, and others the gas. The 2,000 year plus Sichuan salt industry has drilled approximately 130,000 brine and gas wells, and 10% of those were in the immediate Zigong area. Zigong has a cumulative gas production over this period of over 30 billion cubic metres. The area continues to be a major salt producer, and many of the historical wells are still in production.

One minor detail I found interesting. When I had first read of bamboo pipelines, I wondered how the barriers separating the segments within the bamboo were dealt with. Did they drill holes through these compartment walls with long augur bits to create pipe? My curiosity was satisfied by one of the displays depicting the process of turning bamboo into pipe. Each length of bamboo was cut in half, down its length. The segment walls were removed, and the insides of the bamboo further hollowed out to create a smooth inside surface of constant interior diameter. The two sections were then put back together and bonded with a glue made from a mixture of lime and tree seed oil. It was further bound together with twine inset into grooves in the outside surface of the bamboo, to prevent fraying, especially for down hole use where the hole’s rock walls would scrape against the exterior surface of the bamboo pipe as it was repeatedly lifted and lowered during drilling and production operations. Similar glue and twine techniques were used to link and splice pipe line sections together end-to-end in an airtight fashion. As recently as the 1950s there was still over 95km of bamboo pipeline in operation in the Zigong area.

Being earth scientists, Andrew, Bo and I were naturally curious about the geology of the region, and the knowledge the ancient drillers had of the subsurface. Did they practice geology, or geophysics, in some form? Did they draw diagrams of the sub-surface and choose new drilling locations based on geological models? This is one area the museum displays do not touch on. However, it is known that well locations were chosen based on the distribution of existing gas and brine wells, and on a variety of surface clues. Brine and gas seeps were obvious indicators of a good location. The salt drillers looked for a salt “frosting” on the surface rocks, or the smell of brine. Yellow brine wells (high in ferric chloride) were usually drilled into yellow sandstone outcrops, while black brine wells (containing hydrogen sulfide) were drilled into cracked sandstones with a black crust. Brine only wells were usually drilled on hillsides, while gas producing wells were usually drilled on hilltops, suggesting that the topography reflected the underlying geological structures. However, surface clues would not have revealed much about targets down towards 1000m depth, so we’re left to speculate on whether geological skills advanced along with the drilling technology.

Drilling hose(rotary hose)made according to API 7K spec, applies for flexible hose connection between the top of oil drilling stand pipe and vertical moved swivel joint in well drilling, well cementing, work-over and down-hole servicing operation. drilling hose is also used to adjust the installation mistake between drilling pipe line and stand pipe to avoid shake, sometimes to transfer high pressure oil and water base mud with the lowest aniline point of 60°C from the swivel pipe in high pressure, and down-hole operation high medium such as water, oil etc, drilling rotary hose can be used for prefect work too.

A kelly hose is a piece of mining equipment. Specifically, it refers to a piece of equipment used in the mining of fluid or semi-fluid resources, such as oil and natural gas. The main purpose of a kelly hose is to allow the drill string to be raised and lowered at the same time that drill fluid is being pumped through it. This is important, as drill fluid is critical to the mining process.

In most cases, a kelly hose is classified as a large-diameter hose. This means that the inside diameter is usually between 3 and 5 inches (about 7.6 cm and 12.7 cm). This wide diameter allows for a significant rate of flow and reduces the likelihood of a blockage occurring in the hose.

The kelly hose must also be able to withstand large amounts of pressure. This applies primarily to the pressure of the fluid flowing through the hose. For this reason, it is often made of highly durable material and is generally reinforced with steel.

In a derrick or drilling rig, the kelly hose connects the standpipe, which is the rigid metal shaft that delivers the mining fluid, to the swivel, which is the piece that supports the weight of and controls the rotation of the drill string. Its purpose is to provide a flexible drilling fluid conduit, as a rigid conduit would be unable to move with the swivel and would therefore disallow movement of the drill string and, subsequently, the bit.

The drilling fluid, sometimes called drilling mud, carried by a kelly hose is critical to operations in several ways. It keeps the bit cool, which helps reduce friction and failure. It also cleans the bit and carries away drill cuttings so they cannot damage the drill assembly. Some varieties are used for additional purposes, such as preventing corrosion and providing hydrostatic pressure. Drilling fluid is not necessarily fluid, but may, in fact, be a solid, liquid, gas or other combined form.

The kelly hose is so named because of its connection with the kelly, the actual mechanical piece that ejects the drilling fluid over the drill string. It may alternatively be called a mud hose or a rotary hose. Failure can occur, despite the rugged construction of the hose. Such failure can lead to damage to the rig or a failure to operate. Failed kelly hoses must be repaired or replaced before mining operations can safely and effectively resume.

Viscosity, power consumption, commercial availability and lifecycle cost analysis are all important considerations in pump sizing. An automated spreadsheet method helps engineers take those factors into account in centrifugal pump selection

The specific speed is a useful index to help get a general idea of the type of pump to be chosen. All pumps can be broadly classified with a “dimensional” number, as shown in Equation (16).
