Modeling transient pressure at the bottom of coal seam gas well
Abstract
Based on the non-balanced sorption model, this paper proposes mathematical modeling of coal seam gas in both quasi-steady flowing state and non-steady flowing state. It further reports on studies of the relationship between non-dimensional pressure and time at the well-bottom assuming the round closure and definite pressure with constant flow rate of coal seam gas.
