【摘要】 本文将模糊数学的方法运用于石油地质工作中的油层孔隙结构分析。根据实际获得的压汞资料,对孔隙结构进行树状多级综合评判。并且,通过建立渗透率贡献(?)的隶属函数μ_k(x),对有效孔隙下限进行预测。更多还原

【Abstract】 In this paper,the method of Fuzzy mathematics is applied to the describe the pore-structure of the reservoir rock,mercury-injection using in Shuanghe oilfield.A model of multiple stage synthetic evaluation in the shape of a tree is devised to evaluate the porous structure quantitutively,and the membership function μ_K(x) of permeable contribution (?) of the porous media is set up to determine a lower threshold value of the medium.更多还原
