摘要
基于高尚堡深层油藏精细描述研究结果,设计了6种油藏开发方案,并采用油藏数值模拟方法得出了各方案的采出程度、含水变化规律等指标。按照油藏整体开发效果评价、油藏部分区域水平井开发效果评价、不同开发阶段水平井开发效果评价和不同水平井井型开发效果评价四个评价步骤,分析和评价水平井在多层系复杂断块油藏开发过程中的适应性。得出针对复杂断块油藏,水平井早期应用效果优于开发中后期,应采用以直井为主水平井为辅的混合注采井网,水平井井型以大斜度井和双分支水平井生产状况较好,为同类油藏的水平井开发提供借鉴。
Six development schemes were designed based on the result of fine reservoir description of Gaoshangbao oilfield,and the a ratio of total oil produced to OOIP and water-cut change laws of every scheme were obtained by applying reservoir numerical simulation method.According to the development effectiveness evaluation of the overall and partial reservoir and the different development stage and different type of horizontal wells,the applicability of horizontal wells development in fault block reservoir was studied.The conclusion was that the earlier adopting horizontal wells,the better result will be got.The mixed injection-production well pattern which included vertical wells and horizontal wells was good to carry out in complicated fault block reservoirs.The production total rate of high-deviated wells and double branch horizontal wells was higher than other types well.
