SJP intro


SJ Petroleum Machinery Co. (SJ for short), one of the backbone enterprises of petroleum drilling and production equipment in China, was established in 1941, with 78 years of experience up to now. Located in Jingzhou, a historical and cultural ancient city in Hubei, SJ is mainly engaged in research, development, manufacturing and service of land and offshore oil/gas exploration and development equipment, covering drilling equipment,
cementing equipment, workover equipment, fracturing equipment, coiled tubing unit, snubbing rig, offshore equipment and high pressure fluid control products. Meanwhile, SJ has been actively expanding into on-site equipment inspection, testing, overhaul and modification service, to provide integrated solution to oil/gas exploration and development equipment for customers. SJ has passed ISO9001 certification, HSE certification, and National Laboratory Accreditation and Metrology certification, and has been awarded “National Hi-tech Enterprise”, “National Enterprise Technology Center”, “National May-1st Labor Award”, “National Quality Management Excellent Enterprise”, ” China Top 500 Machinery Manufacturers”, and “National Civilized Enterprise”, etc. Our products and technical services have spread all over China and major oil-producing regions in the world. In China, SJ has exported the most drilling/worker rigs, cementing and fracturing equipment.


SJ is focused on the research and development of characteristic drilling rigs for oil/gas exploration field, from truck-mounted drilling rig, automated modular drilling rig, Big Easy drilling rig, full-trailerized electric drilling rig, cold-weather drilling rig, train-rail type drilling rig, helicopter drilling rig, trailerized desert drilling rig, to full-hydraulic drilling rig, etc, featuring fast movement, quick and convenient installation, automatic control and adaptability for complicated environments. These drilling rigs are widely used for oil/gas exploration and development in plain, arctic, desert, mountain, etc, have created series of leading achievements, and have been awarded China Top Brand. Now, SJ has become the backbone enterprise of petroleum drilling rig in China.

Cementing Equipment


SJ is the leading research, development and manufacturing base of cementing equipment in China. We have more than 30 years of experience in cementing package, with proprietary core technologies for series plunger pump, ACM automatic mixing, full automatic cementing truck and unitized equipment. The national China industry standard for cementing units is developed by SJ. Truck-mounted, skid-mounted, or trailer-mounted cementing units for land, desert or offshore area are all available


SJ, the largest workover equipment manufacturing base in China, can provide full series self-propelled workover rigs with maximum hook load ranging from 600kN to 2250kN. We have developed various fast-moving, high-efficiency and energy-saving rigs for different environments. In summary, more than two thousands truck-mounted workover rigs have been produced and sold, among them, nine hundreds rigs are exported to over 30 countries and oil producing areas. SJ is the largest factory in terms of production output and export output.

Fracturing Equipment


SJ is a top-notch development and manufacture base of fracturing package in the world. We possess the self-owned core technologies for series 350-5500HP plunger pumps, fracturing pump trucks, sand blending trucks, instrument vans, manifold trucks, high pressure manifolds, electric fracturing skids, integration of large-scale fracturing package, high-displacement continuous mixing equipment, and network control. With 30 years of experience in developing, manufacturing and service of fracturing equipment, we can provide integrated equipment solution for conventional and unconventional oil and gas fields. Model 2500 fracturing packages, a ”National 863 plan” project, have widely used in the domestic oil fields, creating great economic and social benefits. Model 3000 fracturing package, a “12th-Five-Year major scientific and technological project”, was developed successfully and awarded “the 2nd Prize of National Science and Technology Progress Reward”, and has been used for fracturing operations for reservoir improvement in the shale gas development in Fulin, Chongqing. The research and application of ultra-high Power Electric Fracturing Package, a Key R&D Program of National 13th- Five-Year-Plan, now has been put into production and application in scale.

Our welding teams are accredited up to ASME IX standards


Based on cooperation with international partners and our own innovation, we have mastered core components(injector head, reels) and system integration engineering and manufacturing technologies. Now we can provide series truck-mounted, trailer-mounted and skid mounted, 50~620 kN coiled tubing units. Our CTUs have been widely used in domestic markets, and exported to International market in batch.
Snubbing units


Our snubbing units are designed for direct operation under pressure, without the need of killing the well or release, featuring environmental protection and energy saving. New style safety, environment friendly and energy saving, SDYJ series coiled tubing units are available now. They are all hydraulically driven, with maximum lifting load ranging from 400 to 2700kN (seven categories), covering stand-alone type and auxiliary type. They can be skid-mounted, trailermounted or truck-mounted.


SJ is one of the leading manufacturers of offshore oil drilling equipment in China. With the strong background on developing and manufacturing of land oil drilling equipment, SJ has started to enter the offshore engineering equipment field since the early 1990s, and has maintained the leading advantages in terms of technology and achievement for offshore fixed platform drilling rig/ workover rigs, offshore cementing and fracturing equipment, and offshore manifolds. Our offshore workover rig won the award of Ninth-Five-Year-Plan National Technology Innovation Excellent Project. The rigs have worked in China Bohai Sea, East China sea and South China sea and exported to the overseas market. Three sets of fixed type platform drilling rigs are operating in Bohai Sea, and some were exported to USA, Malaysia, etc. Now we are researching the 9000 m jack-up type drilling package and the design of 1500HP offshore fracturing vessel is under way.
