Application of integral metal screw pump in Shengli Oilfield

2021-05-31
According to Sinopec's website, Shengli Oilfield Petroleum Engineering Technology Research Institute has successfully researched, designed and developed the integral metal screw pump technology. It has operated 17 wells in Shengli Oilfield and has added nearly 5000 tons of oil. Recently, this new technology has obtained the appraisal certificate and acceptance certificate organized by the Ministry of science and technology of Sinopec. The overall achievements have reached the world leading level, and some achievements have reached the world leading level.

What is the most ideal equipment for viscous and high temperature oil production? It is all metal equipment, which is also the cutting-edge technology of the international oil industry. The technology is mainly developed to solve the problems that the ordinary rubber screw pump can not be used in high temperature mining of viscous oil wells, or the rod pump is used to improve the pump energy efficiency. Since 2012, scientific researchers of Shengli Oilfield Engineering College have set up the Sinopec project "research and application of integral metal screw pump", which lasted for five years. They have established the loss calculation model tool of integral metal screw pump, developed the forming method of metal stator of integral metal screw pump, and detected the influence rules of different rotation speed and water content on the unique properties of integral metal screw pump, The evaluation method and application template of integral metal screw pump are formed. On this basis, with the integral metal screw pump as the core, three kinds of lifting modes, i.e. injection production integration, variable flow production and through pump sand sinking and oil digging, are matched. The temperature resistance of the integral metal screw pump can reach 400 ℃, which is far higher than the maximum temperature resistance limit of 150 ℃ of the traditional rubber
