Abstract: This paper analyzes the coal seam distribution，fracture development characteristics，roof?floor lithology，permeability，reservoir pressure，reservoir temperature，gas saturation，adsorption characteristics in Liulin area of Ordos basin. According to these parameters，this paper establishes the reservoir model. Integrated with the production performance，the reservoir model is adjusted after history matching by COMET?3. Finally，production prediction of Well L8indicates that the CBM cumulative production will be459.05×104m3 and the recoveryfactor will be56.12%in15years. The paper comes to a conclusion that the reservoir is favorable for CBM development，and CBM in Liulin area has high value for commercial development
