摘　　要：八面河油田角5-23块为复杂小断块边底水油藏,具有含油小层众多、含油断块小的特点,早期钻井钻高点、打多层,多为多层合采,补孔措施频繁,经过近20年开发,油井高含水、层间出力状况差异大、剩余油分布复杂。为了进一步提高区块的采收率,尝试运用油藏数值模拟方法对该块进行了的剩余油分布研究。根据油藏数值模拟成果,研究制定了该块的开发调整对策。Jiao Block 5-23 in Bamianhe Oilfield is edge bottom water reservoir with complicated small faulted blocks,which features numerous substrata containing oil and small oil blocks.In early drilling,commingling production was generally adopted and reperforating was frequently used.Nearly 20 years of development is responsible for high water cut in oil wells,large differences in interlayer's output and complicated remaining oil distribution.For further raising recovery ratio in the block,the author has tried reservoir numerical simulation method in studying the remaining oil distribution in the block and found out the solutions to development adjustment for the block.
