Abstract

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.
