摘　　要：为了获得理想的煤层气井产能,结合几年来阜新盆地刘家区煤层气开发实践,对煤层气主控地质因素进行综合分析,认为影响刘家区煤层气井产能的主要因素为单井控制的煤层气资源量、地质构造、岩浆活动、煤储层渗透率、临界解吸压力、盖层条件和气井施工工艺。提出了煤层气开发的布井原则和有利区块,可对刘家区或其它煤层气开发区选择有利的煤层气井位提供借鉴。To achieve good coalbed methane well productivity, a comprehensive analysis of the key influencing geologic factors was made combining with recent development of coalbed methane in the wells of Liujia area, Fuxin Basin. The results show that the influencing factors are one well controlling coalbed methane resource, geologic structure, magmatism, permeability of coal reservevoirs, desorption pressure under critical state, conditions of caprocks, and gas well construction techniques. Based on our proposed well-set principal and favorable areas, a good way of choosing favorable coalbed methane well in Liujia area and other areas of development of coalbed methane is suggested.
