A new pump field used more than 250 wells

A new type of oil pump that has been used on a large scale in oilfields has been used on-site in the oilfield. The effect is remarkable and it has been well appraised by the users. Up to now, the new oil pump has been used in the field for 252 times. As a result, the pump has been applied to the site with gas injection and the pumping success rate reached 100%. At the same time, the qualification rate of on-site use is up to 100%. This technology is by the Xinjiang Petroleum Administration Oil Production Technology Research Institute researchers developed a Multi-Function long plunger pump technology. Multi-functional plunger pump technology is the Xinjiang Institute of Petroleum Research Institute researchers put into scientific research project in 2004, the project is the research staff of the hospital system analysis and research currently used in heavy oil thermal recovery of various heavy oil pump excellent Shortcomings, and combined with the characteristics of steam injection in heavy oil fields to carry out research work. Results The hospital researchers through more than two years of continuous exploration, research and development project has been successful. In the subsequent field experiment process, multi-functional long plunger pump technology has been improved, at the same time Xinjiang Institute of Petroleum Research Institute researchers at the scene according to the needs of the oilfield, respectively, completed the three diameters 38,44,57 Specifications of the long plunger pump design work, more than 40 design drawings, and in accordance with the national pumping station indoor test standards, conducted dozens of indoor tests, the results of the sampling rate of 100% pass the test. Based on the success of the technology in the preliminary experiments, researchers at the Institute of Petroleum Exploration Bureau of Xinjiang Petroleum carried out on-site promotion of large-scale oilfields and achieved good results. At the same time, the successful application of technologies has won the trust of oilfield users Better evaluation of the unit. Up to now, the multi-functional long plunger pump has been used 252 times in Xinjiang Oilfield Oil Production Plant, the longest use of more than a year, of which 44 in the low-cost oil field application of a long plunger plunger pump Nearly 100 Taiwan, 38 diameter multi-function long plunger pump 118 units; Xinjiang Oilfield heavy oil company on-site use of 35 units. Through the large-scale popularization and use of the oilfield site, the multi-functional long plunger pump realized the expected concept of the researcher and achieved the scheduled goal. Multi-functional long plunger pump has changed the structure and form of the traditional long plunger pump, using the overall pump cylinder structure. The newly developed multi-function long plunger pump technology to meet the injection of dual-use, on-site operation is simple, easy maintenance, but also to meet the cluster wells, directional wells, inclined wells and horizontal wells pumping needs. In the meantime, it is also possible to perform non-well-killing operations after pumping, especially for heavy oil self-injecting wells with high energy of oil layers. This not only saves the cost of well killing operations but also avoids the damage to the oil formation caused by the well killing operation. At present, the technology has applied for a national patent.
