Some CBM reservoirs have extremely low porosity and permeability, which need hydraulic ,fracturing, to achieve greater yields. Furthermore, the reservoir ,fluid, flow gradually changes from single-phase water flow to gas-water two-phase flow during the production process, which can increase seepage resistance and change the form of pressure propagation.

1.3 Hydraulic ,Fracturing, Hydraulic ,Fracturing, (commonly referred to as "fracking") is the process of injecting at high pressure water and proppants (known as the "frack ,fluid,") down a wellbore. The pressure of the frack ,fluid, on the target formation causes the target formation to fracture, whilst the proppants in the frack ,fluid, hold open the fractures.
