| Abstract: | On the basis of studying the geochemical characteristics of the heavy oil and oil sand in the Xinglongtai reservoir, Shu 1 region, this paper discusses how the vertical inhomogeneity changes crude oils to heavy oils and its control factors. The authors deem that the heavy oil in the region originated from the secondary alteration (including oxidative degradation and biological degradation) of the normal crude oil, but in oppsition to the general degradation tendency, the degree of degradation of the oil increased with the hidden depth of the reservoir. It is inferred that this abnormal degradation tendency is concerned with the lithologic character of the reservoirs. This degradation inhomogeneity is of great practical importance to the oil development in the region. |
