秦家屯油田多轮次调剖效果分析与对策

Effect Analysis and Countermeasures of Multiple Rounds of Profile Control in Qinjiatun Oilfield

2011至2013年秦家屯油田开展了三轮调剖,从筛选调剖剂用量、裂缝影响、多轮次影响等方面来分析该油田多轮调剖效果,得出了前期调剖存在的不足及改进方向,选出了更适合秦家屯油田调剖的堵剂、更适应存在裂缝油田的调剖剂用量计算方法,为秦家屯油田复产后提高采收率及调剖优化提供依据。

Three rounds of profile control were carried out in Qinjiatun Oilfield from 2011 to 2013, and the effects of multiple rounds of profile control were analyzed in terms of profile control agent selection and use, the effect of fractures, and the effect of multiple rounds, etc. The deficiencies of previous profile control and the improvement to be made in the future were identified, a plugging agent more suitable for use in Qinjiatun Oilfield was chosen, and a method of calculating the amount of profile control agent more suitable for the oilfield with fractures was developed, thus providing the basis for enhancing the efficiency of recovery after the production was resumed in Qinjiatun Oilfield.
