Introduction

 SJ Petroleum Machinery Co. (SJ for short), a state-owned enterprise under Sinopec Group, is a China Critical Technological Equipment Nationalization Base and a National Hi-tech Enterprise. SJ, as one of China Top 500 manufacturers, ranks 2nd on the list of China Top 10 Petroleum Drilling and Production Equipment Manufacturers and is rated AAA by China Petrochemical Industry and Banks.  

SJ, initially established in Lanzhou, Gansu in 1941, was moved to Jingzhou,  Hubei in 1969. SJ has started the manufacturing of petroleum drilling and production equipment since the end of 1970s. We have completed the DNC, OA  and CAD/CAPP/PDM/ERP industrial information systems, and are API, ISO9001 and HSE management system certified. We have established and effectively implemented the enterprise legal adviser system and internal control system. SJ is mainly engaged in the development and manufacturing of drilling rigs, workover equipment, cementing equipment, fracturing equipment, offshore drilling and production equipment and high pressure fluid control products, including 200 models of products falling in four major categories and 12 series. 

SJ is a petroleum drilling and production equipment R & D center and a certified technical center in Hubei. We have a relatively complete research and development system, and are authorized to set up a post-doctoral research station. SJ Technical Center has one Science and Technology Management Dept., three research institutes (Research Institute for Drilling and Workover Equipment, Research Institute for Cementing and Fracturing Equipment, Material Process Institute), an Electric Control Institute in Electric Control Branch and a HP Manifold Research Room in Manifold Branch, with 314 persons dedicated to product development and process research. SJ has an evaluation and employment system of lead and responsibility engineers, and has cultivated a group of technical personnel in the field. With this high quality technical team, SJ has mastered the design technologies for drilling rigs (including offshore equipment), workover rigs, cementing units and fracturing equipment, now SJ can provide a complete solution for customers at home and abroad. 

We have a complete production facility, including welding, forging, casting, riveting, heat-treatment, machining, assembling and commissioning, and post-treatment, with more than 2100 sets of precision equipments. We have already set up seven production lines for drawworks, gear boxes, cylinders, masts, high pressure manifolds, plunger pumps and post treatment, and three assembly lines for drilling rigs, workover rigs and cementing and fracturing equipment. Now we can supply 100 drilling rigs, 100 workover rigs, 120 cementing units, 80 fracturing equipments, over 700 pumps, and 150,000 high pressure manifolds each year. We possess a rig assembly yard covering an area of 50,000 square meters, with 24 positions for rigging-up and two offshore rig commissioning sites (four rig positions), where a test of 750ton can be performed and 12 drilling or workover rigs can be assembled and commissioned simultaneously. Our Manifold Branch can provide high pressure manifolds which are interchangeable with world leading manifolds, including various high pressure fluid control products with pressure ratings ranging from 21MPa to 140MPa and sizes from 2’’ to 5’’. Thus, nearly 20 types of equipment and components, such as drilling rigs, workover rigs, snubbing rigs, masts, drawworks, crown block and traveling block, swivels, hydraulic cylinders, reducers, drilling slips, drilling fluid circulating lines, cementing units, fracturing trucks, manifold truck, sand blenders, high pressure pumps, choke and kill manifolds, wellhead units and Christmas trees can be inspected and tested in our factory, to guarantee product design validation and testing before delivery.

We have also set up customer representative offices to facilitate customer’s supervision and third party inspection, thus our product quality and adaptability have been boosted. Up to now, SJ has sold more than 3300 petroleum equipments, among them, over 300 drilling rigs sold in the past 10 years. With the rapid development and technical improvement, SJPETRO brand has been widely recognized in the world market. Recently, SJ has received more and more orders for overseas projects, this is an excellent opportunity for SJ and SJ has gained lots of experience in providing complete package of petroleum equipment.
