One of the instruments that the driller uses to monitor and improve the operating efficiencies of the drilling operation. The actual measurement of weight is made with a hydraulic gauge attached to the dead line of the drilling line. As tension increases in the drilling line, more hydraulic fluid is forced through the instrument, turning the hands of the indicator. The weight that is measured includes everything exerting tension on the wire rope, including the traveling blocks and cable itself. Hence, to have an accurate weight measurement of the drillstring, the driller must first make a zero offset adjustment to account for the traveling blocks and items other than the drillstring. Then the indicated weight will represent the drillstring (drillpipe and bottomhole assembly). However, the driller is only nominally interested in this weight for most operations. The weight of interest is the weight applied to the bit on the bottom of the hole. The driller could simply take the rotating and hanging off bottom weight, say 300,000 pounds [136,200 kg], and subtract from that the amount of rotating on bottom weight, say 250,000 pounds [113,500 kg], to get a bit weight of 50,000 pounds [22,700 kg]. However, most rigs are equipped with a weight indicator that has a second indicator dial that can be set to read zero ("zeroed") with the drillstring hanging free, and works backwards from the main indicator dial. After proper zeroing, any weight set on bottom (that takes weight away from the main dial), has the effect of adding weight to this secondary dial, so that the driller can read weight on bit directly from the dial.

Background technology is at present in oil geology, petroleum prospecting, in the drilling well of various rigs, workover rig or the workover treatment process, indication and record tool hanging load and drilling and the pressure of the drill all use weight indicator when changing, because the weight indicator working environment is located in the field, environment is abominable, work collision, stretching that weight indicator itself is subjected to are quite general, therefore, cause weight indicator very easily to be damaged, repair rate is high, simultaneously, the weight indicator of newly advancing also needs complete detection before coming into operation, and the leading indicator of detection comprises: wireline anchor output pressure error; The fundamental error of weight indicator; The fundamental error of registering instrument; The response limit of the sensitive pin of weight indicator; The instrument management system must not seepage under the maximum working pressure (MWP) condition; The instrument operating ambient temperature.Because weight indicator volume, weight are bigger, many circuits are arranged at its bottom, so trace routine comparatively bothers, and directly place improperly on the ground, place on the table and detect also difficultly, therefore need design the special detection frame.

The summary of the invention the purpose of this utility model designs the vertical verification frame of a kind of weight indicator exactly, with fixing weight indicator, and convenient to its complete detection.The vertical verification frame of a kind of weight indicator of the utility model, it comprises base, platen, pin, spring etc., base is welded by angle bar, four legs are arranged, be the rectangle brandreth, at the upper surface of the base platen that has been welded, platen has only covered the part of base upper surface, pin is welded on the edge of base, on the top of pin spring is installed.The utility model is simple in structure, weight indicator just can be seated at the part that base upper surface does not bind, and utilizes the interspersed circuit in hole of base bottom simultaneously, makes detection more convenient.The spring on pin top is used to toggle weight indicator, makes weight indicator not crooked because of inclined to one side those a period of time.

Embodiment is with reference to accompanying drawing 1, the vertical verification frame of a kind of weight indicator of the utility model, it is by base (1), platen (2), pin (3), spring (4), composition such as bolt and reinforcement, base (1) is welded into rectangle by angle bar, four legs are arranged, be welded with two reinforcements at base upper surface, platen (2) covers the part of base upper surface, rear side at base is welded with two pins (3), two springs (4) are installed on pin (3), because the distance between platen (2) and the pin (3) just in time is equivalent to the width of weight indicator base (1), so weight indicator can steadily place on the base, simultaneously use spring that weight indicator is toggled again, can carry out various detections to it easily.Easy to use for the scene, can seal around the base, be processed into two fan doors in its front, make a casing, be used to deposit testing tool and various accessory.

This article is about the onshore oil rig. For offshore oil rig, see Oil platform. For drilling tunnels, see Tunnel boring machine. For handheld drilling tool, see Drill.

A drilling rig is an integrated system that drills wells, such as oil or water wells, in the earth"s subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers. Drilling rigs can sample subsurface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called "offshore oil rigs" even if they don"t contain a drilling rig). The term "rig" therefore generally refers to the complex equipment that is used to penetrate the surface of the Earth"s crust.

Small to medium-sized drilling rigs are mobile, such as those used in mineral exploration drilling, blast-hole, water wells and environmental investigations. Larger rigs are capable of drilling through thousands of metres of the Earth"s crust, using large "mud pumps" to circulate drilling mud (slurry) through the drill bit and up the casing annulus, for cooling and removing the "cuttings" while a well is drilled. Hoists in the rig can lift hundreds of tons of pipe. Other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas; and in remote locations there can be permanent living accommodation and catering for crews (which may be more than a hundred). Marine rigs may operate thousands of miles distant from the supply base with infrequent crew rotation or cycle.

Antique drilling rig now on display at Western History Museum in Lingle, Wyoming. It was used to drill many water wells in that area—many of those wells are still in use.

Until internal combustion engines were developed in the late 19th century, the main method for drilling rock was muscle power of man or animal. The technique of oil drilling through percussion or rotary drilling has its origins dating back to the ancient Chinese Han Dynasty in 100 BC, where percussion drilling was used to extract natural gas in the Sichuan province.Edwin Drake to drill Pennsylvania"s first oil well in 1859 using small steam engines to power the drilling process rather than by human muscle.Cable tool drilling was developed in ancient China and was used for drilling brine wells. The salt domes also held natural gas, which some wells produced and which was used for evaporation of the brine.

Oil and natural gas drilling rigs are used not only to identify geologic reservoirs, but also used to create holes that allow the extraction of oil or natural gas from those reservoirs. Primarily in onshore oil and gas fields once a well has been drilled, the drilling rig will be moved off of the well and a service rig (a smaller rig) that is purpose-built for completions will be moved on to the well to get the well on line.

Mining drilling rigs are used for two main purposes, exploration drilling which aims to identify the location and quality of a mineral, and production drilling, used in the production-cycle for mining. Drilling rigs used for rock blasting for surface mines vary in size dependent on the size of the hole desired, and is typically classified into smaller pre-split and larger production holes. Underground mining (hard rock) uses a variety of drill rigs dependent on the desired purpose, such as production, bolting, cabling, and tunnelling.

In early oil exploration, drilling rigs were semi-permanent in nature and the derricks were often built on site and left in place after the completion of the well. In more recent times drilling rigs are expensive custom-built machines that can be moved from well to well. Some light duty drilling rigs are like a mobile crane and are more usually used to drill water wells. Larger land rigs must be broken apart into sections and loads to move to a new place, a process which can often take weeks.

Small mobile drilling rigs are also used to drill or bore piles. Rigs can range from 100 short tons (91,000 kg) continuous flight auger (CFA) rigs to small air powered rigs used to drill holes in quarries, etc. These rigs use the same technology and equipment as the oil drilling rigs, just on a smaller scale.

An automated drill rig (ADR) is an automated full-sized walking land-based drill rig that drills long lateral sections in horizontal wells for the oil and gas industry.Athabasca oil sands. According to the "Oil Patch Daily News", "Each rig will generate 50,000 man-hours of work during the construction phase and upon completion, each operating rig will directly and indirectly employ more than 100 workers." Compared to conventional drilling rigs", Ensign, an international oilfield services contractor based in Calgary, Alberta, that makes ADRs claims that they are "safer to operate, have "enhanced controls intelligence," "reduced environmental footprint, quick mobility and advanced communications between field and office."steam assisted gravity drainage (SAGD) applications was mobilized by Deer Creek Energy Limited, a Calgary-based oilsands company.

After the cementing of the casing has been completed, the drilling rig, equipment, and materials are removed from the drill site. A smaller rig, known as a workover rig or completion rig, is moved over the well bore. The smaller rig is used for the remaining completion operations.
