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。
关键词： 煤层瓦斯压力原位探测; 大裂隙系统; 残留煤层瓦斯; 运移特征

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.
Key words： Coalbed gas in-situ exploring; Fracture zone; Residual gas; Movement law.
