摘　　要：煤层瓦斯原位探测技术能够完整的记录煤层瓦斯流体的细节变化。利用煤层瓦斯原位探测技术,对寺河东四盘区3#煤储层流体压力进行测试。3#煤储层的宏观以及显微观察结果表明寺河3#煤储层裂隙系统具有很强的非均质性,抽放后的残留煤层瓦斯流体的运移具有明显的瞬时波动性;该残留气体的压力总体比较低。流体的运移在不同的煤岩体以及不同的裂隙发育带具有不同的特点,流体的压力变化也与裂隙带发育特征有关。Coalbed gas in-situ exploring technology can completely record the details of coalbed gas fluid changes.Using this technology to system test the fluid of Sihe East 4th zone 3^# coalbed reservoir systematically,combined with the 3^# coalbed reservoir underground observations,as well as indoor microscopic observations,the results showed that the fracture system of Sihe East 4th zone 3^# coalbed reservoir is strong heterogeneity;the coalbed gas is the residual of discharging gas,of which the migration has obvious strong fluctuation and transient characteristic;the residual gas does not have high pressure;and the fluid is transported in different coal-rocks and various fractured zones with different movement laws,and its pressure changes in different fracture zones.
