定量描述储层的新途径──成因法

New Method to Predict Petrophysical Properties-Genetic Approcl

储层定量化描述不仅为油气勘探提供有利的靶区，而且能为油气的开采选择合适的方法，对提高开发的成功率与经济效益有着十分重要的意义。因此，不断提高储层定量描述的精确度，反映储集体的真实面貌，乃成为当前国内外油气地质研究领域的热点。本文重点讨论了成因法以及如何应用成因法来预测储集体中岩石物理性质、如孔隙度、渗透率和含水饱和度，以期达到储层定量化描述的目的。

A new method of flow unit approach to describe and predict reservoir petrophysical properties has been proposed recently. This paper describes a genetic approach to reservoir description, which combines lithofacies analysis with discriminant analysis and probability field simulation for the identification and characterization of flow units on the basis of core and log data.
