摘要 化学驱是现阶段油田实际生产中高强度躯替增加原油采收率的技术方法,对老油田残余油的再次开发有着十分重要的意义。分析了化学驱中聚合物驱以及二元和三元复合驱的驱油机理,深入分析了化学驱中各种方法的经济效益以及它们对环境所造成的影响,并且结合当前油价低靡的行情对化学驱方法进行优选,结果表明:聚合物驱仍占主导地位,是油田实际生产中首要的选择。 Chemical flooding is a high-intensity displacement method to increase the oil recovery rate in current oilfields, which is of great significance to the redevelopment of residual oil in old oilfields. In this paper, the mechanism of polymer flooding in chemical flooding was analyzed as well as the flooding mechanism of binary and ternary compound flooding,and economic efficiencies of various methods in the chemical flooding were discussed as well as their impacts on the environment, and optimal chemical flooding methods in low oil price situation were screened out. The results showed that the polymer flooding was still the best method.
