There are many and complex faults in Paleogene strata,Lufeng 13 subsag.The oil enrichment degree in different fault blocks varies greatly.Quantitative research on the fault-controlled reservoir and the relationship between faults and oil enrichment is beneficial for future oil exploration in the study area.The fault-controls was comprehensively analyzed and quantified from three aspects:oil supply,transport and charging capacities.The coupling coefficient of fault-controlled reservoir was established.The cou-pling coefficient has a good linear relationship with the reserves abundance,which accords with the actual geological law.Under the guidance of quantitative evaluation,a medium-sized oil field(C-9)has been discovered.This method can predict the favorable areas and provide guidance for Paleogene strata with rich hydrocarbon generation.
