Research on Permeability of Double State Flow in CBM Reservoir
Coal absolute permeability and relative permeability of water-gas are the necessary parameters to production forecast of CBM exploration. Using steady state method to measure absolute permeability, phase permeability and relative permeability of water-gas, the paper studies the related records and gets effective result. It also gives the conclusion of the osculatory relation of permeability and directions of sample stratification, and exposits the phenomenon and regular that relative permeability of water-gas changes with increasing seepage pressure for the same stratification.
