摘　　要：准确的测量煤层气含气量对于煤层气储量计算、勘探开发等具有重要的意义。煤层气含气量总体积是指损失气体积、实测的气体体积、残余气体积的总和。煤层气含气量影响因素主要有:取心暴露时间、煤心破碎程度、暴露时地面温度、大气压力、损失气的计算方法、解吸终止时间等。Accurate measurement of gas content within CBM has great meanings for reserve calculation and exploration ＆ de- velopment of CBM. The total volume of gas content within CBM refers to the aggregation of gas loss volume, prac, tically lested gas volume and residual gas volume. The main influencing factors of gas content witilin CBM are coring exposure time, coal core fragmentation degree, ground temperature during exposure time, atmospheric pressure, gas loss calculation method, desorption termination time, etc.
