Mango parameters and the evolution of parents and its children indicate that cru de oil exists difference in Ledong and Dongfang area. It show they come from dif ferent source rock or have distinguishable effect during forming reservoir. The light hydrocarbon parameters of crude oil coming from Ya 13-1 structure vary be tween the parameters of two area crude oil which indicates kerogen matrix types and depositional environment are different. The difference of hydrogen and carbo n isotope composition in Ledong and Dongfang crude oil shows the depositional en vironment of their source rock or changeable effect during forming reservoir are different. The biomarks parameters also make sure the discrepancy of crude oil property in two area and prove the same oil source that come from Ya 13-1 struc ture. The study of aromatic hydrocarbon and fatty acid obtained the same results .
Key words: Light hydrocarbon parameter; Isotope; Fatty acid; Yingqiong basin.
