Abstract: The third phase of coal-bed gas exploitation lasts long time, so stable seepage laws of this phase shouldbe studied. Pseudo pressure function is adopted to resolve this problem by J. P. Seidle. The pressure distributionequations in the formation of multi-lateral well for coalbed methane are constructed on the basis of pressure super-position and mirror image reflection theory. Pressure drop influence on the deliverability is considered. By couplingwellbore flow and reservoir stable seepage flow, the deliverability calculation model and its solution method formulti-lateral well are established. Rules of influence on deliverability of multi-lateral well for coalbed methane isanalyzed.
Key words: coalbed methane, multi-lateral well, steady seepage, coupling model, configuration of laterals20
