【摘要】：从化学驱油技术、稠油热采技术、注气驱油技术和微生物驱油技术4个方面,对中国石化提高采收率技术的研究进展及应用进行了概述,归纳了各项技术的适用条件、应用结果及存在问题,并讨论了中国石化提高采收率技术规模化应用的方向。研究结果指出:化学驱油技术已成为中国石化提高采收率技术的主体,其中的聚合物驱和二元复合驱已成熟配套,并实现规模化应用。非均相复合驱技术在孤岛中一区聚合物驱后油藏试验成功,预计可提高采收率7.3%。在稠油热采技术中,热化学吞吐、井网加密和普通稠油水驱转热采技术已推广应用,蒸汽驱和热化学蒸汽驱技术仍处于工业化试验阶段。注气驱油技术和微生物采油技术处于现场试验阶段,且均已取得较好的增产效果。中国石化提高采收率技术工业化应用的方向是继续研究适应复杂油藏条件的驱油剂、驱油体系和流度控制技术,并对成熟技术进行组合应用。
[Abstract]:The research progress and application of enhanced oil recovery technology in Sinopec are summarized from four aspects: chemical flooding technology, heavy oil thermal recovery technology, gas injection flooding technology and microbial flooding technology. The applicable conditions, application results and existing problems of each technology are summarized, and the direction of large-scale application of enhanced recovery technology in Sinopec is discussed. The results show that chemical flooding technology has become the main body of Sinopec enhanced oil recovery technology, in which polymer flooding and binary composite flooding have been matured and applied on a large scale. The heterogeneous composite flooding technology has been successfully tested in the reservoir after polymer flooding in the first area of Gudao, and it is expected that the recovery can be increased by 7.3%. In heavy oil thermal recovery technology, thermochemical huff and puff, well pattern encryption and ordinary heavy oil water drive thermal recovery technology have been popularized and applied, steam drive and thermochemical steam drive technology is still in the industrial test stage. Gas injection flooding technology and microbial oil recovery technology are in the field test stage, and have achieved good results in increasing production. The direction of industrial application of enhanced oil recovery technology in Sinopec is to continue to study the oil displacement agent, displacement system and mobility control technology suitable for complex reservoir conditions, and to combine and apply the mature technology.
