摘要

研究提出利用常规测井资料有效评价致密砂岩气储层的解释思路及解释方法。在解释思路上

采用传统定量解释与特殊评价相结合的综合评价思路;在评价方法上

采用在地质背景分析基础上

分构造、分沉积建立岩电评价参数;分物性建立可变岩电参数;在分析储层岩性、物性背景及敏感曲线特征基础上采用三孔隙度含气指示法有效判别气层属性。通过与实验数据及大量测试结果对比

气层识别准确率明显提高。

Abstract

In this paper

we proposed the interpretation thought and method for the tight sandstone gas reservoirs. Firstly

we took the comprehensive evaluation method

combining the traditional quantitative interpretation with the special evaluation and the analysis of geological background to establish the parameters of rock electricity evaluation by dividing structure and deposition. Then

we used the variation of porosity to establish the variation of rock electrical parameters. Based on the analysis of reservoir lithology

physical property background and sensitive curve characteristics

we used the gas bearing attributes of three kinds of porosity curves to identify the gas reservoir attributes. By comparing with the test data and a large number of test results

the accuracy of gas reservoir identification was improved obviously.
