| Abstract | A new model is developed for the hydraulic fractured well in coalbed, by considering the following aspects: methane desorption phenomena, finite conductivity vertical fracture, and asymmetry of the fracture about the well. A new parameter is introduced to describe the storage of the fracture, which is named combined fracture storage. Another new concept called fracture asymmetry coefficient is used to define the asymmetry of the fracture about the well. FEM is used to solve the new mathematic model. Both well test type curve and seepage field are got and analyzed. The effects of combined fracture storage, desorption factor, the fracture conductivity, fracture asymmetry coefficient, etc. on type curve are all discussed in detail in this paper. |
