Abstract: Trace vanadium and nickel in crude oil and the ratio of V/Ni are used for identificaticn of crude oil of continental and marine origin. Based on data from 17 oil fields in China, it has been concluded that generally speaking oil with V/Ni<1 is of continental origin and that with V/Ni1 is of marine origin. The form of occurrence of vanadium and nickel in crude oil and their possible sources are discussed with reference to data available from home and foreign sources.

摘要： 本文介绍了原油中痕量金属钒、镍与V/Ni比值划分我国陆相原油与海相原油。根据我国十七个油田测量数据可以导出:一般V/Ni1为陆相原油;V/Ni1为海相原油。文章还根据国内外资料探讨了痕量金属钒、镍在原油中存在形式和可能的来源。
