摘　　要：以剩余油分布规律为基础,研究了分层配注方案的优选方法并编制了相应的软件.利用该方法,根据各层段剩余油分布可确定配注水量,以及增注井、不调整井、限注井的不同比例组合可得到各个配注方案.利用模糊数学方法对编制的各个配注方案进行了优选.应用结果表明,方案预测与实际调整层段符合率为81.5%.Optimizing method of layered water injection project was studied based on the laws of the distribution of remaining oil, and corresponding software was worked out. With this method, water injection rate can be determined based on the laws of distribution of remaining oil. Various projects can be obtained through different combination of augmented injection wells, unadjusted wells and restricted injection wells. Projects can be optimized using fuzzy mathematics. Field application indicates that coincidence rate of project forecast with practical adjusted layers is 81.5%.
