摘要
中国海陆交互相页岩气资源量丰富,它的储层有特殊属性。通过对沁水盆地采取的467件样品进行的岩矿鉴定、TOC、Ro、扫描电镜、X衍射、热解有机碳、含气量、超低渗透率、等温吸附等多个项次的测试,发现在采用体积法进行储量计算的参数选择中,泥岩厚度、层系划分、含气量等方面与常规天燃气及煤层气均有较大差异。宜采用适用于含煤地层页岩气储量估算的方法与换算。
The shale gas resource is rich in the continental shelf of China, and it＇s reservoir has special properties. We take 467 samples in the Qinshui basin and test them. These tests are rock ore appraisal, TOC, Ro, scanning electron microscopy, X-ray diffraction, pyrolysis of organic carbon, air content, ultra-low permeability and isothermal adsorption. Then we found that there are a lot of differences between conventional natural gas and coalbed methane in the parts of mudstone thickness, formation division and air content when we use the volume method to calculate the reserves.It is quite suitable to take the estimating approaches and conversion when dealing with the coal reserves in the trub.
