摘要
The relationship between fault activity and hydrocarbon accumulation and enrichment in Nanpu Depression was studied by the technologies of quantitative evaluation on fault activity and large amount analyses of microscopic fluorescence,homogenization temperatures of fluid inclusions and burial history.The results show that besides 2 boundary faults,there are 45 growth faults which cut source rocks and are active in the phase of Minghuazhen Formation. According to the fault throw in early stage of Minghuazhen Formation and inactive phase of the faults,the 45 faults are divided into 3 types named A,B and C.Hydrocarbon distribution is mainly enriched in the favorable traps near type A and type B faults which are relative more active and whose inactive phases are later.
