摘　　要：针对塔河油田水平井高含水问题,结合实际资料,建立单井数值模型,利用精细油藏数值模拟技术实现水平井堵水参数分析及优化,对堵剂注入量、堵剂类型、顶替液注入量以及堵后工作制度等相关参数进行分析。结果表明:堵水效果与堵剂在平面上的展布距离相关,不能盲目增加堵剂用量以达到增油效果;4种类型堵剂中,冻胶堵剂效果最好,乳状液次之,颗粒型堵剂效果较差;其中颗粒型堵剂注入一定量的顶替液后,堵水效果明显增强;数模与油井动态数据均表明,水平井堵水再生产时,控液生产堵水效果最优。In view of the problems of high water cut in horizontal wells of Tahe Oilfield,numerical simulation models of individual wells are established;water shut-off parameters are analyzed and optimized by using fine reservoir description technology;and the parameters of the injection volume of water shut-off agent,water shut-off types,the injection volume of displacing liquid,work system after water shut-off,etc.are analyzed based on actual data.The results show that water shut-off is related to the lateral distribution of water shut-off agent and aimless increase in the volume of water shut-off doesn't certainly gain oil;in the 4 types of water shut-off agent,the effectiveness of jelly agent is the best of all,emulsion liquid agent is good and grain agent is poor;for grain agent,the effectiveness of water shut-off increases after injection of a certain volume of displacing liquid;numerical simulation and reservoir performance data show that the effectiveness of controlling liquid production is the best when a horizontal well restarts production after water shut-off.
