摘要
秦家屯油田SN106区块位于松辽盆地南部东南隆起梨树断陷东北部,投入注水后,出现平面、纵向非均质性强,含水上升率大,自然递减大,油井受效不均一等问题,文章通过注采井组分析、地层压力评价、注水特征评价,提出补孔、封层开采、酸化等手段,以达到改善水驱效果、提高油田采收率的目的。
The SN106 Blocke of Qinjiatun Oil field, is located in the southern Songliao Basin and eastern slope of the Lishu Fault. Plane and vertical heterogeneity, low recovery, high cut rising rate and natural decline rate are verified are before water injection development. The paper through the analysis of injection-production well group, evaluation of formation pressure, the evaluation of water flooding feature, in order to improve water flooding efficiency, using the method of hole filling, seal extraction and acidification. For improving the recovery rate has important significance of oilfield.
