摘 要: 萨北开发区北三区东部位于大庆长垣萨尔图油田北部纯油区内,属于河流—三角洲沉积,砂泥质交互分布,非均质极为严重。为进一步提高油田开发效果,编制并调整开发方案,结合北三东模拟区生产资料,分析其存在的问题:1) 从产量构成上分析出三次加密后油井产量递减幅度增大;2) 通过对比水驱井网及不含三次加密的水驱井网的甲型水驱规律曲线,得出三次加密井并没有提高研究区的采收率。
关 键 词: 油气田开发工程;三次加密;产量构成;采收率

Abstract: The east of Beisan block of Sabei developing area is located in the Saertu pure oil field of Changyuan, Daqing, which belongs to river-delta depositional system. The sand and mud are distributed interactively, and the heterogeneity is very serious. For further improving the development effect of the reservoir and compiling and adjusting the development scheme, based on the production data of Beisandong simulated domain, the existed problem is analyzed. Firstly, analysis from the production composition shows that the decreasing amplitude becomes much larger after the third round infill drilling. Secondly, through comparing the alpha water flooding law curve of flooding pattern of the wells including the third round infilling wells and that of pattern of the wells not including the third round infilling, it is found that the third round infilling wells do not improve the recovery of target area.
Key words: oil and gas field development engineering; the third round infilling well; composition of oil production; recovery
