The research of transformability is an important guarantee for the effective development of CBM, For revealing the effects of physical properties and select favorable development areas have a great guiding effect. Application of geological data and fracturing data, the key parameters such as gas content, seam thickness and permeability are interpreted and evaluated, the transformability index of coal seam transformability are formed, which can quantitative evaluation of coal seam transformability to select the best vantage point. The main knowledge and achievements are as follows: (1) Coal structure is a key parameter for quantitative characterization of coal reservoirs, In this study, GSI model is established based on logging responses of different coal structures, this model has strong applicability. (2) The measured data are obtained by isothermal adsorption experiment, analysis and calculation of well logging data are the main means, apply Huang's model, a set of in-situ stress evaluation method based on coal reservoir is developed. (3) The evaluation model of coal seam transformability index is established by AHP evaluation method. The key factors restricting the transformability of coal and rock reservoir in this area are discovered.
