摘要: The Liaozhong Sag is one of the major oil-bearing areas in offshore Bohai Bay Basin and obviously characterized by late-stage hydrocarbon accumulation. In this paper our study was focused on strong activities tectonic movement sag. terms source rock thermal history analysis, generation, migration accumulation hydrocarbon, enrichment pattern were summarized. Apatite fission track analysis evolutionary Easy% Ro model simulation showed that rocks became matured rapidly at time 5.1Ma from present. Fault area mainly result fault transportation. Fluid inclusions indicated period oil gas reservoirs Our rapid vertical transportation, near ra...
