Abstract:
In order to further understand the structural deformation mechanism of the middle section of Fufeng thrust nappe structural belt in Huainan coalfield and its control on the content of coalbed methane(CBM), and guide the exploration and development of CBM, the diversity characteristics of thrust nappe structural deformation, formation mechanism and its relationship with generation and distribution of CBM were revealed in Xinji and Luolian coalfields; through detailed structural analysis and comparison, combined with regional geological background, the latest geological data of coalfield exploration and production were used to reveal the control of tectonic deformation on generation and distribution of CBM; the burial-thermal evolution history of coal-bearing strata in Xinji and Luolian coalfields was simulated by Thermodel for Windows software. The results show that Luolian coalfield is characterized by imbricated fan structural deformation, and the in-situ system structural deformation is weak under the action of Indosinian pushing from south to north; affected by the uplift of coal-series basement, Xinji coalfield is characterized by double thrust nappe structure deformation, and a large number of extensional structures are formed along the crankshaft of the fold in the in-situ system during longitudinal flexural fold deformation; the coal-bearing strata in Xinji and Luolian coalfields experience four stages of structural burial and thermal evolution history, but the paleogeothermal gradient and coal metamorphism degree in Xinji coalfield are obviously higher; the variation of paleotemperature gradient caused by the coupling of coal-series basement uplift and deformation structure is the fundamental reason for the differential generation and enrichment of CBM in Xinji and Luolian coalfields; the spatial distribution of CBM in Xinji and Luolian coalfields is obviously correlated with the tectonic position, and mainly affected by the degree of structural deformation and burial depth.
