Transient Analysis of Coalbed Methane Flow in a Coupled Reservoir-Wellbore System
Considering the effects of friction and kinetic energy change,a wellbore model wasdeveloped for the coalbed methane flow based on conservation of mass and momentum,and then acoupled reservoir-wellbore model for the coalbed methane flow was presented by the comprehensweresearch on the wellbore flow,reservoir flow and the deformability of coal seams. The coupledmathematical model was solved by the finite-differenee method,and in a coal seam with constantpressure outer boundary,the curves of the wellhead pressure and density for the constant-rate productionwell were plotted along with the time．
