复杂岩性油藏储层微型构造研究

Study on microstructure of complex lithologic reservoir

在储层微型构造成因及类型分析的基础上,应用二次趋势面剩余分析方法对储层微型构造进行研究,并对储层微型构造与剩余油分布关系进行分析认为,正向微型构造区为剩余油相对富集区,负向微型构造区为相对高含水区,对油田今后调整挖潜具有重要指导意义。

On the basis of microstructure genesis and type analysis,surplus analysis method of secondary trend surface is used to study reservoir microstructure and the relation between microstructure and residual oil distribution.It is thought that the positive microstructure zone is relatively rich in residual oil,and the negative microstructure zone has relatively high water cut.This study is of guidance importance to future adjustment and potential tapping.
