砂岩储层胶结指数m的一种标定方法

A Calibration Method for Cementation Exponent m of Sand Reservoir

本文从分析阿尔奇公式出发，引出对影响储层胶结指数ｍ的各种因素进行标定的问题；提出对储层泥质含量、钙质含量进行标定的单因素线性标定法和对环境因素、测量因素进行标定的邻层比值标定法。通过实例分析表明本文的标定方法简单、有效、实用，为提高测井解释精度，更好地进行多井储层评价和油藏描述奠定了基础。

In light of the analysis of Archie's formula,calibration of the factors influencing cementation exponent m is proposed in this paper.It includes single factor--linear calibration for clay and calcium content and shoulder-bed ratio calibration forenvironment and measurements effects. The analysis of field examples shows thatthe calibration methods mentioned above are simple, effective and practical. It isvery helpful to the improvement of the accuracy of logging interpretation and bettermulti-well reservoir evaluation.
