| 摘 要： | 煤储层压力是煤层气开发的重要参数，它可以通过试井方法获取，华北部分矿区的试井资料表明，煤储层压力的变化较大，其主要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，当含气饱和度一定时，储层压力对煤层气井早期的气产率和水产率有较大影响。

| Abstract: | The pressure of coal reservoir,an important parameter in the development of coalbed methane,can be determined through well test.The well test information of some mine areas in North China shows that the pressure of coal reservoirs vary in a wide range.The main influencing factors are tectonic stress,height and burial depth of groundwater,the mineralization degree of groundwater and so on.When the coalbed methane saturation is constant,the pressure of coal reservoir has a relatively great influence on the methane and water production rates in the early period of coalbeed gas wells. |
