Abstract: With the decrease of proved reserves of shallow CBM, more and more attention has been paid to deep CBM. Taking Hengling block in Northeast Qinshui Basin as an example, the spatial distribution of reservoir, coal seam thickness, gas bearing property and reservoir characteristics in Hengling block are predicted by using seismic facies controlled inversion technology and by means of thickness calibration, effective reservoir thickness analysis, multi-scale edge detection and lithology identification, the results show that: The method of facies controlled nonlinear random inversion has achieved remarkable results in the inversion of target reservoir. The seismic wave characteristics of the 3 coal reservoirs determined in the block are consistent with the logging results; The thickness of No.15 coal seam is between 4~7 m, and the distribution is NNE direction. The thickness distribution of the whole area is stable, the thickest part is in the northwest, and the thinnest part is in the Midwest; The gas bearing characteristics of No.15 coal seam are obvious in the middle and north of the block, with the maximum effective reservoir thickness of 4.5 m; The porosity distribution of No. 15 coal is uniform, ranging from 4% to 6%; The area with thick coal seam has larger porosity, and the porosity corresponding to the high gas content part is well developed,The coal seam fractures are mainly distributed in the west of the block,The fracture zone with developed faults has well developed fractures, and the fracture density gradually decreases with the increase of depth. At the same time, according to the above research results and the actual development experience, 4 favorable areas of coal seam 15 and 4 comprehensive favorable areas of coalbed methane are delineated.
