摘要
东辛油田营 31断块油层薄、分布广 ,采用直井开发 ,由于高含水合采、层间干扰等问题 ,造成薄层油藏采收率低。为了改善薄油层的储量动用状况 ,探索水平井开采薄层剩余油方式 ,进行了薄油层水平井先导试验。实施情况表明 ,薄层水平井技术的实施可改善储层的渗流能力和开发效果。
The problems of commingled production at high water cut and interlayer interference result in low recovery efficiency in oil reservoirs with thin formations after vertical wells are applied in Ying31 fault block of Dongxin oilfield where oilbearing formations are thin with wide distribution. In order to increase the produced reserves in thin oilbearing formations and explore the production pattern of remaining oil by horizontal well, pilot experiment is done. The implemented results show that horizontal well technology applied in thin oilbearing formations can improve the seepage flow capacity and development effect of reservoirs.
