Title: L-FVM for Unsteady Seepage Flow in Low Permeability Coalbed

Abstract

The significant feature of coalbed in China is the low permeability. A new unsteady seepage flow model isdeveloped for the low permeability coalbed by considering the startup pressure gradient and methane desorption effect.Since the complexity of the problem, a new method which we call it ''L-FVM'' is developed, based on comparing the normal numerical calculation methods and comprehension research on FVM. The results show that L-FVM has the same precission but higher calculating velocity than normal FVM. This result is very important for monitoring the area pressure drawdown in coalbed methane engineering
