Abstract

Abstract

In accordance with the fracturing and producing mechanism in coalbed methane well,and combining the knowledge of fluid mechanics,linear elastic fracture mechanics,thermal transfer, computing mathematics and software engineering,the three-dimensional hydraulic fracture propagating and dynamical production predicting models for coalbed methane well is put forward.The fracture propagation model takes the variation of rock mechanical properties and in-situ stress distribution into consideration.The dynamic performance prediction model takes the gas production mechanism into consideration.With these models,a three-dimensional hydraulic fracturing optimum design software for coalbed methane well is developed,and its practicality and reliability have been proved by example computation.
