尕斯库勒油田E31油藏经过20多年的注水开发,已经进入中高含水阶段,受地层非均质性的影响,注入水单层突进严重,尤其是主力层。从剩余油分布来看,次非主力小层剩余地质储量占全油藏剩余储量的49.4%,有很大潜力。选取部分高含水且主力层无潜力的井区进行次非主力层的动用,措施效果与理论分析对比,分析剩余油研究的准确性。
Gas reservoir E31 reservoir after 20 years of water injection development, has entered the high water cut stage, affected by formation heterogeneity, injection of water monolayer sudden serious, especially the main strata. Judging from the remaining oil distribution, the secondary non-main small residual geological reserves account for 49.4% of the total reserve of the whole reservoir, which has great potential. Select some of the high water content and the main potential of the wells in the non-sub-main non-useful layer, the effect of the measures and theoretical analysis, analysis of the remaining oil research accuracy.
