摘　　要：针对目前包1块西南部高含水期开发现状，应用油藏工程，从水驱开发效果评价指标体系入手，对综合含水率、注水利用率、水驱指数及最终采收率等指标进行了客观分析，结果表明，该区块在完善注采井网、转换注采方式、提高水驱控制程度、追求上产需要的同时，控水措施没有及时跟上。要改善目前含水上升状况．今后在开展稳油措施的同时，应进一步加强找、堵水等控水工作，以保证开发效果向好的方向发展。按照目前开发趋势预测，包1块水驱采收率可达14．20％．可采储量可达109．50×10^4t。Aiming at current Baol block southwest high water period development status, reservoir engineering is applied to start from water flooding effect evaluation index system to objectively analyze integrated water content, water injection rate, water flooding index and the ultimate recovery, rate and the like, the results show that water control measures are not followed up in time when the block perfects injection mining well net, converts injection mining patterns, improves the water flooding control degree and pursues upper production needs. In order to improve the cun＇ent situation of water rising, oil stabilizing measures should developed in the future, water control work such as finding water, sealing water and the like can be further intensified for guaranteeing that the development effect is developed to positive direction. According to current development trend, it is estimated that Baol Block water drive oil recovery rate can be up to 14.20%, and recoverable reserves are up to 109.50×10^4t.
