Research on the Characteristics of Coal Reservoir Porosity and the Influence of Specific Surface Area on Coal Adsorption Capacity

LI Yanan;LI Guizhong;CHEN Zhenhong;Langfang Branch of Research Institute of Petroleum Exploration and Development,CNPC;  
The representative coal samples of the coalbed methane development zone is selected,and optical microscope and scanning electron microscope are used for experimental measurement in the paper to research on the mineral content in coal and pore development situation.By the analysis of the image,the pore structure feature and degree of development of coals with different components,is represented,which provides theoretical support for the CBM exploration and development.At the same time,research is conducted on the relation between the specific surface area and the adsorption content.
