... pressure area is wider. Numerical simulation results provide guidance for exploitation through injection of heat into low permeability coal seam in our country. 1 INTRODUCTION Coal-bed methane (known as gas) is a clean energy which is associated with coal. There are rich coalbed methane resources...

... has the acid property, but the drilling fluid shows the alkalinity, so it is easy to cause acid-base neutralization producing metal salts and block coalbed methane channel. Therefore, in order to protect the coal reservoir effectively, reduce the pollution on coal reservoir, and improve the recovery...
