Analysis of Coalbed Methane Inter-Well Interference

Article Preview

Abstract:

On the base of the storage, migration and production mechanisms of Coalbed Methane (CBM), the gas-water two phase differential equations describing the seepage of CBM are set up to calculate reservoir pressure and productivity in vertical well pattern, to analysis the propagation characteristics of formation pressure and the influence of inter-well interference and various influencing factors of inter-well interference. The results show that Inter-well interference can speed up both the reservoir pressure drop and the desorption of adsorbed gas, increase the gas well productivity, and enhance the ultimate recovery in the coalbed methane field.
