摘　　要：为了深入研究煤层气井合理配产及其排采控制方法,延长气井高产稳产期,以某区块E6井组为例,进行产能影响因素分析,得到排采各阶段合理生产制度。结果表明:稳产期短主要原因是排采半径有限,裂缝延伸有限,原始区域渗透率低;排采制度不合理,达到转折压力后继续提产。In order to further study the reasonable production allocation and drainage control methods of COALbed methane Wells and prolong the high and stable production period of gas Wells,taking E6 well group of a certain block as an example,the influencing factors of productivity were analyzed and the reasonable production system of each stage of drainage and production was obtained.The results show that the main reasons for the short stable production period are limited drainage radius.1)limited fracture extension and low permeability in the original area.The second is that the drainage system is unreasonable,and production continues to be raised after reaching the turning pressure.
