Evaluation on Coalbed Methane Favourable Zone of Jixi Basin

Haibo WANG

Abstract


The stress field and seepage field are the important control factors of the CBM accumulation, preservation and effective exploitation. In order to effectively filter out the CBM favourable zone of a block in Jixi basin, the regional stress field and seepage field are studied. Firstly, the permeability sensitivity experiment under different effective stress and temperature are carried out with the JHCF intelligent core flow test instrument, the mathematical physics equations that reflect the relation between the coal permeability and the effective stress and temperature is established. Through analyzing the geological structure, reservoir and hydrogeological characteristics, a three-dimensional geological model is constructed. Applying the finite element numerical analysis method, the regional stress field, temperature field, permeability field and the seepage field are simulated. The result shows: the north central part has lower stress, higher permeability and lower velocity of seepage than other fields. It is conducive to the structural preservation; water power saving and efficient Exploitation for CBM, where can be the dessert zone for CBM exploration and development.
