摘　　要：煤层含气量和临界解吸压力是煤层气开发中的重要参数。含气量大小是评价煤层气开发潜力的基础,临界解吸压力高低则决定着排水降压幅度。煤层气井临界解吸压力与煤层含气量存在一定关系,通过开发期煤层气井临界解析压力可测算煤层气含气量,结合各井测算的含气量、含气量样品取样和测试等方面综合研究,重新认识古交邢家社煤层气区块含气量分布规律。对比勘探期认识规律,对区内的气藏分布特点形成了新的认识,有利于指导区块煤层气下步的滚动开发。The gas content and critical desorption pressure of coal seam are important parameters in coalbed methane development.The gas content is the basis for evaluating the development potential of coalbed methane,and the critical desorption pressure determines the drainage pressure reduction range.There is a certain relationship between the critical desorption pressure of coalbed methane wells and the gas content of the coal seam.The gas content can be calculated through the critical analytical pressure of coalbed methane wells in the development period.Combined with the comprehensive research on the measured gas content and the sampling and testing of gas content samples of each well,we can re-understand the gas content distribution law of Xingjiashe Block in Gujiao.Comparing with the law understood in the exploration period,a new understanding of the distribution characteristics of gas reservoirs in the area is formed,which is conducive to guide the rolling development of coalbed methane in next step of the Block.
