微构造分析方法在油藏精细描述中的应用

摘要

在油藏描述中，结合微结构的应用分析，我们指出其在油藏描述中的重要作用。可以恢复砂体基底面和顶面的微小变化；可以发现与总趋势一致而局部又不尽相同的微幅度构造或微体差异、在背斜构造---岩性油藏中，通过微局部分析确定更准确的含油边界、经过精细储层微构造分析排除假断层。%In combination with application analysis of micro structure in the description of reservoir,we pointed out its important functions in the description of reservoir; to recover the subtle changes on the top surface and basal bottom of the sandy body; to find some micro range structures and micro differences identical to the general trend of the original strata structure but varied locally; to determine more accurate oil bearing borders through micro local analysis in anticline structure-litho logic reservoir;to exclude false fault through micro structure analysis on fine reservoir.
