KE, Sun et al. The magma thermal field and the shallow-level gas accumulation of tight gas reservoirs in the middle-eastern parts of the Qinshui Basin. Earth Sci. Res. J. [online]. 2019, vol.23, n.1, pp.27-34. ISSN 1794-6190.  https://doi.org/10.15446/esrj.v23n1.78805.

In this study, the metal-non-metal mineral gas-water hydrothermal concept is used to analyze the movement channels of magmatic heating water. Further, the concept of fractures-faults-cracks microfissures hierarchical configuration of the movement channels of magmatic heating water is proposed. In addition, the magma thermal field formed by magmatic heating water movement is studied and analyzed. Based on the basin simulation method, which is combined with the paleo-tectonic evolution analysis and restoration of the ancient burial depth in the middle-eastern parts of the Qinshui Basin, the tectonic evolution history, thermal evolution history, and hydrocarbon generation and exhaustion history of tight gas reservoirs in the Yushe-Wuxiang block in the middle-eastern parts of the Qinshui Basin have been investigated. On the basis of the theories and methods that are proposed in this study, the hierarchical configuration of fractures-faults-cracks microfissures movement channels of magmatic heating water in the Yushe-Wuxiang block in the middle-eastern parts of the Qinshui Basin was studied and analyzed. It is observed that the magmatic heating water rises to the source formation through the movement channels of hierarchical configuration, heats the source rocks, accelerates the evolution of the source rock in the shallow layer, and forms a tight gas reservoir
