Abstract: Based on geological，seismic and geochemical data，by means of fluid inclusion microfluorometric and thermodetecting
techniques，this paper focuses on the study of reservoir-forming patterns and enrichment regulation of typical hydrocarbon
accumulation zone in Huizhou Sag. The results show that oil from Wenchang source rock distributes widely in Huizhou
Sag，hydrocarbon migrating vertically through faults or vertically then laterally through compound transport system，which
experienced two accumulation periods，so the reservoir-forming patterns of Huixi—Liuhua accumulation zone can be divided
into single source–short distance–migrated vertically–multi–phase pattern，mixed source–short distance–migrated vertically–
multi–phase pattern，mixed source–short distance–migrated vertically and laterally–multi–phase pattern，single source–far
distance–migrated vertically and laterally–one–phase pattern. And reservoir forming pattern of Huizhou—Lufeng accumulation
zone is single source–short distance–migrated vertically–multi–phase episodic pattern.

Key words: Huizhou Sag, oil-source correlation, passage system, enclosure, reservoir-forming pattern
