濮城南区沙二下油藏综合治理效果分析

为了实现濮城油田南区沙二下油藏高含水末期开发水平的稳定，根据本层系油层平面、层间的非均质性严重；水井井下技术状况恶化，有效注水点减少；局部地区剩余油比较富集等特点，通过做小层沉积相图和小层水淹图，找出含同饱和度较高的区域或小层，制定出以水井调睡油井补孔为主的综合治理方案。方案实施后，该油世故的平面和层间矛盾得到了很好的改善，各项开发指标达到了预期的目的，取得了较为明显的经济效益和社会效益，为进入中

The Comprehensive Adjustment Effect of Pucheng Oilfield Southern Reservoir S_2 Lower Part

In order to stabilise the development level of pucheng oilfield southern reservoir S2 lower part in high water cut stage, we have found higher oil saturation area or layer and worked out a comprehensive adjustment project-controling profile of water well and perforating of oil well by drawing layered sedimentary faces and watered out plate, according to characteristics, such as the intramational and interbedded controdictory,the worse bottom-hole conditions, the fewer effective water wells, the different watered out degrees of oil layer and remaining oil of some area is richer. After implementation of the project, the contradictory of intraformtional and interbedded of the reservoir has been improved all kinds of development indeses have reached anticipated purpose, we abtained remarkable social and ecnomic profits, this paper points out a divection to control water cut and stabilise oil production and increasing of reserve and stimulation of production in high water cut stage.
