摘　　要：韩城地区煤储层压力异常是影响参数试验井煤层气产出主要的原因。储层压力的影响因素有构造应力、地下水头高度及埋深、地下水矿化度等。储层压力对煤层气井产能的影响 ,涉及解吸压力与储层压力的比值。比值越高 。The abnormity of the pressure of coal reservoir is an important reason for affecting the coal bed gas development. The major influencing factors are tectonic stress, height and burial depth of groundwater, the mineralization ability in groundwater and so on. The influence of reservoir pressure on coal bed gas wells is related to the ratio of dispelled pressure to reservoir pressure. The higher the ratio, the greater productive ability of the coal bed methane well.

关 键 词：煤层气 储层压力 构造应力 解吸压力
