为了探索特高含水期增产挖潜方向,以孤东油田七区西东部为研究对象,在剩余油分析的基础上,应用渗流理论、油藏工程及动态分析法进行了研究,配套相应的工艺技术,制定了平面、层间、层内剩余油挖潜方法,取得了较好效果,探索了特高含水期多层水驱油藏增产措施新路子。 In order to explore the direction of increasing production and tapping potential during the ultra-high water cut stage, taking the west and east of the seven districts of Gudong Oilfield as the research object, based on the remaining oil analysis, the paper applied seepage theory, reservoir engineering and dynamic analysis to study the corresponding process technology , Developed the method of tapping the remaining oil in the plane, the interlayer and the layer, and achieved good results. A new approach to increase the production of multi-layer water-flooding reservoirs in the ultra-high water cut stage was explored.
