Abstract：Based on the research of biomarker combined characteristics,oil and gas source,maturity and degree of secondary reconstruction could be discussed which is the effective method to analyses hydrocarbon origin,genesis of petroleum and oilsource correlation.By making the most of biomarker types and combined characteristics,the geochemical significance will be researched.Oil-source correlation had been studied by becteria degradation and biomarker combined characteristics.The distribution of n-alkanes and isoprene shows that various types of crude oil are developed.That is,two main quite different crude oils are developed which are rich in 4-methylstane and rich in gamma-waxy in the study area.The two different crude oils come from Sha 3 and Sha 4 respectively.
