Abstract: With the acceleration of the global energy structure transformation, deep coalbed methane as an important unconventional natural gas resource has become a strategic replacement area for China's natural gas production increase. As an important part of the Bohai Bay Basin, the Jizhong Depression has undergone multiple tectonic evolutions in its Carboniferous-Permian coal-bearing strata, presenting complex geological characteristics and coalbed methane enrichment patterns. Based on drilling, logging and experimental test data, this paper systematically analyzes the geological characteristics, main controlling factors of enrichment and accumulation models of deep coalbed methane in the Jizhong Depression, and proposes a favorable exploration area selection scheme. The research shows that the deep coal seams in the Jizhong Depression are thick (the maximum single layer of Taiyuan Formation is 25 meters), with significant burial depth differences (1000-5600 meters), and the vitrinite reflectance (Ro) of the coal rocks generally ranges between 0.65% and 0.95%, with vitrinite as the main maceral component (46.7%-97.4%). The thermal maturity is significantly affected by volcanic baking, and the local vitrinite reflectance (Ro) is as high as 4.6%. The gas content of the coal seam (6-18 m³/t) is closely related to the coal thickness, pressure coefficient and preservation conditions. The weak overpressure environment (pressure coefficient > 1.15) and stable cap rock (breakthrough pressure of carbonaceous mudstone 15-29 MPa) in the deep part promote gas enrichment. The study reveals that anomalous heat flow triggered by volcanic activity is a key geological factor enhancing coalbed methane generation, and the spatio-temporal configuration of secondary hydrocarbon generation and structural preservation conditions dominates the accumulation process. Through comprehensive evaluation, the middle to outer belt of the Wena Slope and the northeastern part of the Dacheng Uplift are classified as Class I favorable areas, with advantages such as large coal seam thickness (6-8 meters), high gas generation intensity (> 110 m³/t), and large Langmuir volume (average 11.39-12.42 m³/t). The research results provide theoretical support for the exploration and development of deep coalbed methane in the Jizhong Depression and offer a reference for the evaluation of coalbed methane in similar residual faulted basins.
