In order to effectually resolve the problems as embarrassing solving and cumbersome calculation in design and simulation of hydraulic fracturing in coal petrography, the productivity prediction analysis software of horizontal wells has been developed in this study based on the object-oriented visual programming environment. The analysis software can determine the rock mechanics parameters, the distribution of crustal stress and the coalbed methane production, which can greatly improve the work efficiency of the engineering staff. The software has better applicability and can provide a foundation for the analysis of CBM productivity prediction. The results show that: simulation analysis is of high precision, can satisfy the actual engineering needs. Fracture number and half-length have a greater impact on fracturing horizontal well production; moreover, crack width almost has no influence on production.
Key words: Low permeability gas reservoir, Fractured horizontal well, Production prediction, Seepage near-wellbore, Fracture geometry parameters, ,
