A series of black marine oils with similar chemical compos ition distributed in Hade 4 Oilfield and correlative areas, which are derived fr om the similar source rocks showed by oil source correlation studies based on ag e-specific biomarkers. By the studies of qualitative and quantitative analysis, it can be shown that the concentration and internal composition of terpenoids, such as drimanes, tricyclicterpanes and hopanes, to some extent, are related to oil maturity. In this point, the characteristics of terpanes occurence can be us ed as a reference for the oil source correlation studies of mature marine oils. When ratios of C15-8β(H)-drimane to C16-8β(H)- and ratios of t ricyclicterpanes to hopanes are used for the purpose of oil source correlation s tudy, great attention should be paid to the phenomenon characterized by occurren ce of terpanes in Hade 4 Oilfield and correlative areas.
