油田上产策略研究OA

In view of the problem of further production increase after the mining right block of Shengli Oilfield in the Junggar Basin had been built into a million ton oilfield and stable production for 8 years,the countermeasures for oil field production increase were proposed and carried out.Oil and gas development enterprises often face frequent reports of successful exploration and the situation of no rice left for development.The reason lies in that the discovered reserves are difficult to develop,and the production is also stable.Seven development paradigms have been formed based on the characteristics of shallow burial,high crude oil viscosity,and the development of edge water in the southern part of Block 6 of Chunfeng Oilfield,as well as the changes in development contradictions at different development stages.Among them,the experiences of nitrogen injection assisted horizontal wells,microbial oil recovery in oil-water transition zone,metering of super heavy oil wells,and collaborative development of steam huff and puff,steam flooding and hot water flooding are worthy of in-depth summary and promotion.Aiming at the problem of high quality development of ultra-deep reservoir in Yongjin Oilfield,the existing data are reinterpreted.The abnormal high pressure and fracture development of Jurassic in Yongjin Oilfield contribute to high production.Only by persisting in original innovation,independent thinking and using mathematical thinking to solve the difficult problems in oilfield development,can we make a breakthrough in the scale development of Yongjin Oilfield.
