摘　　要：在煤层气试验井组的开发阶段,为了增产或稳产,需要运用煤层气藏工程,对开发的关键问题,如气藏饱和状态、排采效果、解吸压降漏斗演变、井型选择及井网调整等,进行有效地分析评价。本文在煤层气藏工程的基本理论基础上,结合具体实例,给出了对一煤层气井组开发阶段关键问题的探讨思路,相比于非系统化的分析,可以更好地应用于实践。During the development stage of CBM testing well group, in order to increase or stabilize the production, CBM reservoir engineering project should used to effectively analyze and evaluate the key problems for development, including the saturation condition of the reservoir, the production effect, the evolution of desorption pressure drop funnel, the selection of well type, the adjustment of well pattern, etc. Based on the theory of CBM reservoir engineering and practical examples, the paper provide the train of thought on the key problems in the development stage of a CBM testing well group. Compared with some non-systematic analysis, the thought can be better applied in practice.
