摘要
宝饶油田吉 4 6断块属于复杂断块中—低渗透油藏 ,储层物性差 ,平面非均质性极强。投入开发后出现水井蹩压 ,油井不见效 ,产量递减大的矛盾。利用地层测试资料结合构造、储层研究及沉积微相划分进行了深入研究 ,在对储层非均质特性、沉积特征、油层连通状况等有了清楚的认识后 ,确定了整体压裂改造方案。 1997～ 1998年整体压裂引效实施后减缓了产量递减速度 ,提高了油井的注水见效程度 ,改善了区块的整体开发效果。
Ji46 fault block of Baorao oil field is a complicated and highly heterogeneous fault block oil reservoir with mid-low permeability. After the field put into production, the water injection wells pressured-out very often, and the oil production declined rapidly. Therefore, a whole hydraulic fracture stimulation treatment plan was designed after an integral study on formation test data, depositional systems, zone connection relation. The wells production conditions were improved after the whole hydraulic fracture adopted in 1997～1998, which the oil production decline was slow down through the effective water injection.
