通过对深成变质作用与岩浆变质作用WY煤层气储层物质构成、孔隙发育、比表面积、吸附/解吸实验分析认为,WY变质类型的判定标志之一是小孔以下孔隙比例为96%。解吸作用方式取决于解吸热与吸附热的差值,晋城寺河地区井筒降压满足于WY煤层气解吸的能耗,解吸率高达66%。排水-降压-解吸的排采模式适应于本地区煤层气的开发。煤层气开采应以解吸热与吸附热差值为基础确定解吸方式。

By plutonic metamorphism and magmatic metamorphism WY CBM reservoir material composition , porosity develop-ment, surface area, adsorption /desorption experiments , Analysis, one of the hallmarks of WY metamorphic type to determine is the proportion of pores in the holes above 96%.Desorption mode of action depends on the difference between the heat of desorp-tion and heat of adsorption.Jin Cheng Si He wellbore antihypertensive to meet WY CBM desorption energy consumption , desorp-tion rate as high as 66%.Drainage-Step down -desorption mining model to adapt to the development of CBM in the region , CBM mining should be based on the difference between the heat of desorption and heat of adsorption and to determine the desorp -tion mode.
