Abstract

Based on the stress distribution model of a horizontal well, the calculation model on the fracture pressure of the coalbed methane (CBM) horizontal well is developed. This model deals not only with initiation of the matrix fracture, but also of shear and open fractures. The effects of the cleat parameters and spatial orientation of the well on the fracture character are considered.
