摘要
Abstract
The third phase of coal-bed gas exploitation lasts long time, so stable seepage laws of this phase should be studied. Pseudo pressure function is adopted to resolve this problem by J. P. Seidle. The pressure distribution equations in the formation of multi-lateral well for coalbed methane are constructed on the basis of pressure superposition and mirror image reflection theory. Pressure drop influence on the deliverability is considered. By coupling wellbore flow and reservoir stable seepage flow, the deliverability calculation model and its solution method for multi-lateral well are established. Rules of influence on deliverability of multi-lateral well for coalbed methane is analyzed.关键词
