摘要
吉林油田的地质条件决定了90%以上的试油层要进行压裂改造。对于压后大排量的试油井层,如果能够快速排液,将减少地层二次污染。压裂与水力泵排液求产工艺技术两者的有机结合,极大提高了试油效率,缩短了试油周期,减少压裂液对地层的污染。特别对解决深井、高产井、稠油井、间喷井等试油难点问题,具有十分明显的优势,是一项有前途的实用技术。
That geologic situation in Jilin oilfield determines 99% of testing layers to be fractured.According to big volume of fowl back at postfrac,the second pollution to formation decreases if flow back is done quickly.Integrating tech of fracture with back flow to acquire productivity by hydraulic pump greatly increases oil testing efficiency,shortens testing cycle,decreases damage to formation.Particularly to testing problems of that be solved in deep,high temperature,dense oil and discontinuous flow wells,it has an obvious advantage which is a prospecting practical tech.
