Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Based on the law of conservation of mass of fluid mechanics, considering the orthotropic physical properties of coal cleats and different seepage characteristics in the orientation of the face and butt cleats, the mathematical model of fluid flow is established. According to the fully implicit difference method, time and spatial discretization of the model lead to a set of nonlinear equations, which can be transferred into a group of linear equations. On the basis of double-media fully implicit method, the linear equations is obtained, which can be solved using the Jacobi-iteration preconditioner because of its high stability and fast convergence speed of the solution positively. By using the mathematical model to analyze the ZP-1 well in Qinshui Basin, the pressure distribution is obtained and the effect of orthotropic physical properties of coal cleats on pressure is analyzed. The mathematical model lays a foundation for coalbed gas exploitation.
