Dynamic evolution process of shale gas generation, accumulation, adjustment, loss, and the formation and evolution of overpressure in Well GX-1. HEP is hydrocarbon expansion pressurization, CMTP is clay mineral transformation pressurization, KCGP is kerogen cracking gas pressurization, COCGP is crude oil cracking gas pressurization, and TUP is tectonic uplift pressurization. T1f and T1t are the Feixianguan and Tongjiezi formations of the Lower Triassic, T2+3 in the Middle and Upper Triassic, and S1s and S2h are Shiniulan and Hanjiadian formations of the Lower and Middle Silurian
