双河油田油层微构造特征对剩余油分布的影响

The influence and Significance of the Reservoir Microstructure on Remaining Oil Distribution

摘要: 通过对双河油田主力油层微构造研究，总结出油层微构造特征及其主要类型，它包括正向微构造、负向微构造和斜面微构造等。生产实例表明正向微构造为剩余油富集区，负向微构造为严重水淹区。建议在制定油田开发加密调整方案时应充分考虑微构造因素，尽可能把加密生产井钻在正向微构造上，负向微构造只能钻注水井。

Abstract: Studying the major reservoir microstructure in Shuanghe Oil Field,this paper point out that positive microstructure is the remaining oil abundance zone,negative microstructurc is severe watered out areaSuggests that infill wells should be planned on the positive microstructure area,and injection wells on the negative.
