摘要
为解决安塞特低渗透油田开发中后期生产区块综合含水逐年升高、采收率提高难度大的问题,引进了先进的微生物采油技术,通过菌种优选、菌液性能评价以及合理注入参数界限选择,成功地开展了矿场研究和试验。试验结果证实,微生物驱油具有较好的降水增油作用,是特低渗透油藏提高采收率技术的发展方向。
An advanced microbial oil recovery technology is introduced to solve the problem of increased composite water cut year by year and the difficult of enhancing recovery ratio in ultra-low permeability reservoir of Ansai oilfield.Field research and tests are successfully carried out through strain selection,performance evaluation of broth and limits selection of reasonable injection parameters.The result confirms that microbial oil recovery has a well effect on decrea-sing water cut and increasing oil.This technology is a new direction in research on enhancing recovery ratio.
