Abstract: To further study potential petroleum resources in Lufeng13 fault structural belt, crude oil sources of all oilfields and oil-bearing structures of the belt are analyzed on the basis of biomarker assemblage and geological background of the area. Different levels of secondary migration pathways of oil are discussed based on effective pathway thickness and migration intensity. Biomarker compounds and migration tracer parameters are used by studying the hydrocarbon migration directions of the belt. Hydrocarbon charging history of the belt is discussed as well, according to the homogeneity temperature and burial history of fluid inclusion in the reservoir.

Key words: Pearl River Mouth Basin, Lufeng13 fault structural belt, secondary migration superiority pathway, oil charging history, biomarker compounds; effective pathway thickness, neutral nitrogen compounds, fluid inclusion
