赵庄井田3号煤层气储层物性分析

Physical Property Analysis of No.3 Coalbed Methane Reservoir in Zhaozhuang Minefield

对赵庄井田3号煤层气储层物性进行分析和研究得出:3号煤层除具有典型的煤层含气量高、煤层含气饱和度低、煤层渗透率低、煤储层压力低等"三低一高"特征外,还具有煤储气空间良好、煤吸附甲烷能力强且吸附量大、煤的吸附时间长等特征。总体而言,3号煤层气储层物性相对较差,对其进行煤层气开发难度较大。

The results show that the No.3 coal seam has a typical coal seam with high gas content, low coal seam saturation, low coal seam permeability, low coal reservoir pressure, and so on. In addition , the coal seam also has many other features such as good coal storage space, coal adsorption capacity and strong adsorption capacity of coal, long coal adsorption time, and so on. In general, the physical properties of No.3 coalbed methane reservoirs are relatively poor, and the development of CBM is diffcult.
