摘　　要：文章通过井间干扰试井测试,储层评价定量计算和动态数值模拟三种手段,评价得出开发前期的开发部署及工艺改造难以控制区块整体资源,无法形成井组正向干扰降压的开发矛盾。为此,系统开展煤层气井组调整优化加密方案,并在区块进行先导试验,实现盘活区域存量资源,形成井间耦合干扰,老井增产稳产的技术对策,目前已取的一些认识并持续推广相关工作,对改善气藏的开发效果具有一定成效。Through means of inter-well interference well test,quantitative calculation of reservoir evaluation and dynamic numerical simulation,it is estimated that the development deployment and process transformation in the early stage of development are difficult to control the overall resources of the Block,and the development contradiction of positive interference and pressure reduction of well groups cannot be formed.For this reason,the coalbed methane well group infilling scheme for adjustment and optimization is systematically carried out and the pilot test in the block is conducted to activate the regional stock resources.The inter-well coupling interference is formed,and the technical countermeasures for increasing and stabilizing the production of the old wells are implemented.At present,we have gained some knowledge and continued to promote relevant work,which has a certain effect on improving the development effect of gas reservoirs.
