| Abstract: | The component and distribution character of naphthenic acid of the crude oil, the component character of fatty acid of the highly acidic crude oil and the trace element and rare - earth element, and the geochemical character of satisfied hydrocarbon are studied in the Muglad Basin and the Melut Basin in Sultan. Original source material feature and maturity of the crude oil in this area are analyzed. And also the effect of the original source material and its depositional environment, the organic maturity and the biodegradation on the acid value of the crud oil. The research shows that the biodegradation is the key element of the generation of the highly acidic crude oil. |
