模糊相似选择在储集层综合评价中的应用
|
摘要
针对鸭西白垩系储集层具有低孔、低渗和高泥质含量的特点,综合利用钻井、测井、岩屑录井、取心分析以及试油资料,对储集层岩性、物性、含油性与电性的因果关系进行了统计分析,确定了该区储集层物性、含油性以及多种敏感参数,并应用模糊相似优先选择法,建立了储集层因素集与评语集之间的隶属函数,得到了模糊相似优先选择关系矩阵,通过截割矩阵处理,综合考虑多个地质测井参数,判断其相似程度的优先级,对储集层性质做出评价。实践证明该方法具有较好的地质效果。
Yaxi reservoir of Cretaceous is characterized by dense lithology,poor petrophysics,low porosity,low permeability and high shaliness.This paper comprehensively applied the various data from drilling,well logging,cutting logging,core analysis and production test,and statistically analyzed the consequences among lithology,petrophysical,petroliferous and electric properties.By defining these sensitive parameters and applying fuzzy analog optimum seeking method,the subordinate function between factor set and point set of reservoirs is es-tablished,obtaining corresponding matrix with this method.In the truncated processing of matrix,consideration of several geological parame-ters from well logs is used to judge their similarities and preferred rating,finally,offering results of the evaluation of reservoir characteristics.Field application of this method shows good effects in geological studies.
