摘　　要：通过对已发表文献中的孔隙纵横比谱资料的统计分析,提出通过简化孔隙纵横比谱,利用纵、横波速度及总孔隙度资料,根据Kuster-Toksz显式方程估算孔隙纵横比分布、直接求解组分孔隙度参数、判断储层孔隙类型的思路和方法.通过理论模型计算、实际井资料处理以及与Anselmetti等判断灰岩储层孔隙类型经验方法的对比分析,证明了上述方法的可行性及有效性,从而得到了一种简化孔隙纵横比谱、快速判断储层孔隙类型的简单实用方法.According to the statistical analyses of the data of the reservoir pore aspect ratio distribution from the open literatures,it is proposed that Kuster-Toksz equation is used for simplifying the reservoir pore aspect ratio distribution,computing the component porosities and predicting the reservoir pore types.The feasibility and validity of this method can be proved by the comparison of the mathematical computation results with the processing results of field well-logging data and the results obtained by the pore type predicting method proposed by Anselmetti and Eberli.This is a simple and practical method for simplifying the aspect ratio distribution of reservoir pore and quickly predicting the type of it.
