摘　　要：随着油田开发逐渐进入中后期,以及地层的严重非均质性,注入水往往沿着强吸水层或部位突进,大大降低了水驱开发效果。调剖改善注水井的吸水剖面提高采收程度也越来越显现成效。根据油田区块获取的参数以及对调剖井选择的影响,选择调剖因子,采用变权方法计算出综合考虑各因素的综合因子,进行选择调剖井;将选择出的调剖井调剖效果与实际区块生产中该方法未推荐使用的调剖井的调剖效果进行比较分析。The heterogeneity of reservoir is becoming more and more serious in oil field at later stage of oilfield development. The fingering of injected water formed along the thief formation and greatly reduced the effect of flood effectiveness. Profile control can improve the water infection profile so as to improve recovery efficiency that is becoming more and more significant. According to the effect of profile control by the parameters of the block, it chooses profile control factors. It calculates the comprehensive factors which considered various factors by variable weight method. Based on the comprehensive factors above,it selects the profile control wells. The field application shows that the method of choosing the profile control well group is more reasonable and reliable.
