Abstract
The organic geochemistry characteristics of source rocks and oil sands in Well Hu 41,Well Hu 83 in Huzhuangji area are studied,by which a preliminary judgement is made that the type of kerogen of Es_3 source rock is a mixed type with high maturity,and its depositional environment is saltness reduction one.Es_3 crude oil is matured oil,Es_2 crude oil is low mature oil,Es_3 reservoir oil is of self-generated and self-stored oil,the crude oil in Es_2 is of different source from that of Es_3.
