针对高尚堡油田高5断块油藏开发效果差的问题,在精细三维地质建模和数值模拟的基础上对高5断块剩余油分布进行分类,并根据剩余油不同分布特点,依据二次开发理论,对高5断块井网进行优化,开发层系进行重组调整。二次开发后大幅度提高了水驱控制程度和动用程度,水驱采收率由原来的20%提高到24%。

After thirty years of development there are many problems in Gao5 Block Reservoir of Gaoshangpu oilfield reservoir.Under the fine three-dimensional geology model and numerical simulation,remaining oil satruation distribution of Gao 5 Block is divided into four types： type injection imperfect,uncontrollable well network,retention area and layertype interference.According to the different distribution of remaining oil and redevelopment theory,well network was optimized,and system layer was restructured and adjusted in Gao5 Block.After the redevelopment,waterflood control degree and waterflood use degree were substantially increased.Water flooding recovery ratio rose from 20% to 24%,and good development results were achieved.
