Abstract: Based on fluid inclusion analysis，organic geochemistry data，and pressure simulation，the multiphase thermal fluid activity and natural gas migration-accumulation in the No. 2 fault zone of the BX19-2 structure in eastern Qiongdongnan Basin were studied. The results show that：（1）The natural gas in the BX19-2 structure primarily consists of hydrocarbon gases and CO2，with the hydrocarbon gases being a mix of coal-derived gas and oil-derived gas. However，there is a significant variation in the composition of natural gas across different gas zones. The shallow gas zones in the Sanya Formation exhibit a relatively high content of hydrocarbon gases（volume fraction of 83.93%）and a low content of organogenic CO2（volume fraction of 7.11%）. In contrast， the deeper gas zones in the Lingshui Formation contain relatively lower concentrations of hydrocarbon gases （volume fraction ranging from 16.10% to 76.63%）and higher concentrations of mantle-derived CO2（volume fraction ranging from 18.70% to 81.56%）.（2）Fluid inclusions and geochemical parameters of rocks indicated that the hydrothermal activity was related to hydrocarbon migration，with variations in the depth and extent of the induced thermal anomalies. There were three phases of hydrocarbon-bearing hydrothermal activities occurred during the late Miocene（approximately 8.8 Ma），Pliocene（approximately 4.5 to 4.1 Ma），and Quaternary （approximately 1.1 to 0.1 Ma），respectively.（3）The hydrothermal fluids primarily utilized faults as major conduits for vertical，efficient，and rapid charging. Mantle-derived CO2 from the deep Baodao Sag was injected during the late Pliocene to Quaternary period（approximately 2.2 to 0.5 Ma），displacing the hydrocarbon gases accumulated in the Lingshui Formation. Therefore，traps near the No. 2 fault zone of the Baodao Sag may pose a risk of encountering gas zones with high CO2 content.

Key words: natural gas accumulation, multi-phase thermal fluid activity, vertical migration, fluid inclusion, mantle-derived CO2, Sanya Formation, Lingshui Formation, Cenozoic, No. 2 fault zone, Qiongdongnan Basin
