Based on our extensive experience in the design of land rigs and special vehicles, Sovonex™ truck-mounted drilling rigs are a prime example of advanced engineering.

When drilling on impassable terrain or in remote areas, our truck-mounted drilling rigs’ excellent off-road capability and mobility can make the difference between a drilling operation being commercially feasible or not.

With our extensive experience in the manufacturing of skid-mounted rigs and oilfield vehicles, we are able to design each Sovonex™ mobile rig to individual customer requirements.

Your mobile drilling rig can be 100% made in China, or you can choose rig components from distinguished international suppliers as you like. By default, the following rig components are imported:Main diesel engines: Caterpillar

A key advantage of our truck-mounted rigs is their uniquely constructed chassis. Designed for extreme stability and with a small turn cycle, they give the rigs the power and mobility required for driving on impassable terrains.

Customers can choose between different types of suspensions, including single wheel independent suspension. A mobile rig with independent suspension is especially advantageous when driving in inaccessible mountain regions.

At our production facility in China we manufacture the complete range truck-mounted and trailer mounted drilling rigs capable of drilling wells from 1000m to 4000m. Below you will find a detailed description for each of these rigs.

This 4000m truck-mounted rig with a power of 1000 hp is the most powerful among our mobile rig and often employed in geothermal drilling operations in remote mountain regions.

We do manufacture both truck-mounted and trailer-mounted drilling rigs. While truck-mounted rigs are more compact and easier to handle in rough terrain, the truck of a trailer-mounted rig can be used for other purposes during drilling operations.

The 4000 m mobile rig can optionally be equipped with a top drive system. We provide repair and maintenance services for all major top drive manufacturers like Varco, Canrig, Tesco, BPM, MH, and Bomco

With every drilling rig we send technical staff to the drill site to provide first hand technical support. The engineer responsible for the design of the rig is always part of the service crew.

For your convenience, here is a summary of the benefits of our truck-mounted drilling rigs we consider the most important:Production quality standard API Q1 and ISO 9001

Their exceptional mobility, stability, and ease of operation are the outcome of our extensive experience in the design and production of mobile drilling rigs.

Belonging to the same family, Sovonex™ service rigs comprise many of the technological advantages that result in smooth operation and make the life of our customers’ easier:

Wide selection: At our production facility in China we design and develop workover rigs for service depths ranging from 1,600 m to 8,500 m (5,250 ft-27,900 ft), and workover depths from 2,000 m to 9,000 m (6,600 ft-30,000 ft) for 2 7/8” DP.

Full API coverage: The different components of our well-servicing rigs are manufactured to the following API standards:Steel structures, such as the mast: API Spec 4F

Highly maneuverable : Sovonex™ mobile drilling rigs and self-propelled workover rigs possess excellent driving properties in the desert, mountain, and other impassable terrains.

Reduced NPT: The mast is erected hydraulically to reduce time for rig up and increase safety. Likewise, all rig components have been designed to allow for fast assembly and disassembly.

With every service rig, we send technical staff to our customer to provide first-hand technical support. The engineer responsible for the rig design is always part of the service crew.

The automatic operation equipment for minor workover is mainly composed of a wellhead operation device, hydraulic elevator, pipe and rod transmission and arrangement device and electro-hydraulic control system.

The device adopts the structural form of dispersing the functional modules and integrated installation on the workover rig: with the hydraulic tong, manipulator and anti splash snap device set on the derrick of the workover rig, which can expand and rotate, and the safety slip is installed above the BOP.

The device only needs to install safety slips, which realizes rapid installation and migration and shortens the auxiliary working time. The device has the function of moving back and forth, left and right, which is convenient to align the wellhead. The height of the hydraulic tong is adjustable and can adapt to the wellhead with different heights. Hoisting equipment and special transport vehicles are not required for the installation and removal of the device.

The main electric control box can be installed on the operation vehicle or integrated into the modular wellhead operation device. The make-up torque of various oil pipes is set on the touch screen to realize automatic make-up and break-down. Equipped with video monitoring, process prompt, safety alarm, etc. The control system has a perfect action interlocking function to ensure the safety and reliability of the workover operation process. All of the electric cabinets, sensors, connectors meet the requirement of Explosion-proof on field.

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.

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.

A major breakthrough was achieved around 1050 AD, allowing deeper wells, when solid bamboo pipe was replaced by thin, light, flexible bamboo “cable” (figure 9). This dramatically lowered the weight that needed to be lifted from the surface, a weight that increased with the depth being drilled. By the 1700s Sichuan wells were typically in the range of 300 – 400m deep, and in 1835 the Shenghai Well was the first well in the world to exceed 1,000 metres of depth. In comparison, the deepest wells in the U.S. at that time were about 500m deep. The Sichuan salt producing industry was centred around Zigong, and early photographs show hundreds of producing derricks (“heaven carts”; figure 10), salt stove operations, and the Fuxi River jammed with salt trading boats (figure 11). Brine and natural gas were transported through 100s of kilometres of bamboo pipeline (figure 12).

Figure 10. A photo of Zigong early in the 20th century showing many of the derricks used to drill and produce brine and gas wells. Some of these "Heaven Carts" were over 100m tall!

Figure 13. An ancient sketch originally fro m "The Annals of Salt Law of Sichuan Province". A "Kang Pen" drum is seen in the centre foreground, with gas pipes directly feeding the salt stoves on the right. At the top, brine from a remote well is being carried in buckets by men, who feed it into a bamboo pipeline that runs down to the stoves. One of the carriers is being paid at top left, and it appears that a blow out is depicted on a new well being drilled in the left foreground; maybe the men operating the drill rig have run away, as tragically happened at a Chongqing, Sichuan sour gas well, late 2003.

My brief visit to Sichuan left me intrigued, fascinated, and eager to learn more about China’s ancient technical accomplishments. I can highly recommend the region as a place to visit, not only for its interesting historical sites, but also for its natural beauty (most of Sichuan is mountainous and unpopulated, especially the west, with bamboo forests, and panda bears), its rich culture with many interesting ethnic minorities, its delicious food, great shopping, and its wonderful, friendly people. However, the highlight of my trip was the visit to the Salt Museum, and I hope I have passed on my enthusiasm for this topic to readers.

BEIJING, China, June 2021 – Sinopec SJ Petroleum Machinery Co. (SJP), a leading Chinese oil field equipment maker, has selected Allison Transmission’s 4500 Oil Field Series™ (OFS) for its new light workover rig.

During oil and gas recovery operations from underground reservoirs, chemical and mechanical processes can affect the wellbore, negatively affecting production and causing surface and downhole equipment to fail. Light workover rigs, which can reach remote oil fields swiftly and handle production emergencies efficiently, are always in high demand.

SJP’s latest light workover rig model (GVW at 46 ton) adopts a truck-mounted CNHTC chassis and is equipped with an MC11.40-60 diesel engine rated at 297 kW, coupled to a light and compact Allison Transmission 4500 OFS, which can deliver maximum torque of 1900Nm. The new light workover rig model also carries hydraulic lifting derricks, winches and drilling rigs.

“Our latest model, a light truck-mounted drilling and workover rig, has two main duty cycles: driving the rig to the work site (road mode) to running a second function (work mode), specifically in oil wells that require consistent, durable power and high reliability,” said Zhang Bin, Vice President of SJP Drilling & Repair R&D Center. “Allison has a wide range of oil field transmissions for different work conditions. The Allison 4500 OFS model can be matched with the biggest engines where it can deliver maximum output torque up to 2237 Nm, while being light and compact. It meets the needs of both duty cycles very well.”

This website is using a security service to protect itself from online attacks. The action you just performed triggered the security solution. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data.

A. PURPOSE. This instruction provides guidelines to Federal OSHA and Plan States compliance officers, 7(c)(1) consultants, employers, and employees on the stability of well servicing derricks.

C. ACTION. Regional Administrators and Area Directors shall provide copies of the attached Guideline on the Stability of Well Servicing Derricks to the appropriate Federal an State personnel and ensure that copies are available for distribution to the public upon request.

F. BACKGROUND. There have been several fatalitites as a result of derrick collapses caused by the failure of temporary anchors in the oilwell drilling and servicing industry. Since OSHA has no applicable standards, in many of these incidences, our field office have attempted to cite under the General Duty clause, section 5(a)(1) of the OSHact. This action, however, may not be adequate in addressing the problem. Therefore, to assist OSHA compliance officers, State compliance and consultation personnel, employers, and employees, in the recognition of the hazard of derrick collapse due to the failure of temporary stability systems, OSHA contracted Sigma Associates, Ltd. to develop guidelines detailing the type of temporary stability systems, type of soils and its holding capacity, methods of installing guywire anchors, integrity determination of the system, actual pull testing, and acceptable parameters in liew of actual pull testing (Appendix A).

SCOPE: To provide a representative basis for determining the availability, capability, dependability, reliability of Stability Systems on Land Based Work-Over Rigs and the recommended practices and procedures for their safe use.

A typical double derrick with load guys in place in Figure 2-1. The sub-structure is in place and the unit properly configured to begin installation of the guying system. From this configuration determination can then be made as to the proper selection, location, configuration and holding capacity of guy anchors. Load guys should meet manufacturers recommendations. In the absence of manufacturers recommendations, the minimum wire rope diameter should not be less than that which is recommended by a representative of a major, oil field recognized, wire rope manufacturer.

The rig location area may grade away from the well bore along centerline II at a maximum drop of 1:20. The cross grades, parallel to centerline I, should be level. The area shall provide a minimum bearing capacity of 6000 psf.

There are several States which have statutorily addressed the installation of Guy Anchors. The State of Michigan, for example, references the American Petroleum Institute Specification, API SPEC 4E. Alaska requires that Derricks be effectively guyed, braced, or otherwise engineered to resist overturning in accordance with generally recognized safe practices in the industry. (Industry practices are discussed in Section 1).

It should be pointed out that zone determination is a function of angle and distance. Zone "D" will be discussed first for only Single Derricks may be located in this zone and they will require a minimum 10,000 pound anchor, anywhere in the zone. (This is not the case in other zones which will be discussed later.) Zone "D" ranges through all four quadrants. Your attention is directed to the Northeast Quadrant. The zones parameters begin at the 22.5 degree radial and end at the 67.5 degree radial using line segment OE as the zero radial . The nearest point of Zone "D" to the Well Head is 35 feet and is located on the 45.0 degree radial. (see Southwest Quadrant). The far point of Zone "D" on the 45.0 degree radial is 50 feet. (see Northeast Quadrant).

The minimum anchor holding capacity required for any other location and/or other than single derricks will be determined by Zone and horizontal distance from the "Well Head".

Using the chart: An anchor in Zone "A" located a horizontal distance of 70 feet from the "Well Head" would require an anchor of what minimum holding capacity? On the chart move along the horizontal legend from left to right until you reach 70 feet. At this juncture proceed vertical until you intersect the curved line for Zone "A", now follow the intersecting horizontal line, left toward the vertical legend. We have now determined that the minimum holding capacity for the anchor, at this precise location, is 20,000 pounds.

Standing at the "Well Head", with the well bore immediately to your back, proceed North (in direction monkey board is facing) 24 paces. (The pace length is not as important as the numerical relationship of the units and the consistency of the unit length. The method will work with any unit of length as long as the same unit is used throughout.) Place a stake or other marker at this location (Bench Reference). Turn West 90 degrees and proceed forward 10 paces. At this location turn your body so that the front portion of your anatomy is approximately parallel to the radial of the guy anchor. If the northwest guy anchor is forward of your right shoulder and the southeast guy anchor is aft to the rear of your left shoulder, it can then be presumed that the radial angles are within acceptable parameters. Repeat the procedure from the bench reference, this time to the east, proceed ten paces. In this orientation the northeast anchor should be forward of the left shoulder and the southwest anchor should be aft of the right shoulder.

After the location has been selected and the site prepared, erection of the "DERRICK" and its stabilization system can proceed. Presently the API, AOSC and IADC recommend the following basic procedure, with reference to Figure 5-1:

A survey of 13 drilling contractors operation 193 drilling rigs in northern Canada and Alaska indicated that there is a wide range of experience and operating practices under extremely low temperature conditions. While there is very little precise information available, there have been a sizeable number of failures in portable masts while in the lowering or raising process in winter. Thus the exposure to low temperature failures focuses on mast lowering and raising operations. Based on reports, however, this operation has been accomplished successfully in temperatures as low as -50 degrees F. While the risk may be considerably greater because of the change in physical characteristics of steel at low temperatures, operators may carry on "normal" operations even at extremely low temperatures. This may be accomplished by a program of closely controlled inspection procedures and careful handling and operation. This should reduce damage and impact loading during raising and lowering operations. At the present, there seems to be no widely accepted or soundly supported basis for establishing a critical temperature for limiting the use of these oilfield structures. Experience in the operation of trucks and other heavy equipment exposed to impact forces indicates that -40 degrees F may be the threshold of the temperature range at which the risk of structural failure may increase rapidly. Precautionary measures should be more rigidly practiced at this point. The following recommended practices are included for reference:

If maintained to these tolerances the sags will indicate a pretension of 1000 pounds for crown to ground guywires and 500 pounds for tubing board guywires. this is based on the use of 5/8 inch, 6x19, or 6x37 class, regular lay, ips, IWRC wire rope, installed according to the rigging guidelines set forth in chart depicted in Figure 5-5

The drawing on the following page, Figure 5-4, (SAME AS FIGURE 4-4) is another illustration of the continuing evolution of Rig Stability System engineering and design. It represents the latest API thinking relative to planing and preparing a Rig Stability System.

CAUTION: SOLE EMPHASIS SHOULD NOT BE PLACED ON PULL TESTING OR ALTERNATIVES TO PULL TESTING AS THIS MEASURES ONLY ONE COMPONENT OF THE RIG STABILITY SYSTEM.

The rig contractor should be responsible for the following: a. Insuring that anchor capacities are verified and that anchor spacing and capacity is suitable for the mast guying pattern and anticipated loading.

b. Records of pull testing or records of other methods used to verify temporary anchor capacity should be retained by the rig contractor until the job is complete and the guy wires have been removed from the anchors. The records should indicate the capacity of each anchor, the date of verification, name and phone number of the party responsible for verification, and the soil condition at the time of verification.

OUT OF AN ABUNDANCE OF CAUTION IT IS EXTREMELY IMPORTANT TO POINT OUT THAT THE PREVENTION OF RIG UPSET IS DIRECTLY DEPENDENT ON THE TOTAL INTEGRITY OF THE RIG STABILIZATION SYSTEM. THE SYSTEM INCLUDES ALL OF ITS COMPONENTS AND IS ONLY AS SOUND AS ITS WEAKEST MEMBER.

Our research has concluded, that the latest State-of-the-Art in RIG STABILIZATION is to be found in the pending American Petroleum Institute, Recommended Practice for MAINTENANCE and USE of DRILLING and WELL SERVICING STRUCTURES.
