A Study of Directional Permeability and Gas Injection to Flush Coal Seam Gas Testing Apparatus and Method

Due to the reservoir rocks are often anisotropic in permeability, and traditional permeability testing apparatus cannot well carry out the directional permeability testing. The specialised permeability apparatus known as multi-functional outburst research rig (MFORR) is used to study the directional permeability under various confining pressures, and the relevant testing method and results are introduced as well. The MFORR testing results with...
