摘要: 摘荽准噶尔盆地西北缘的油源问题和原油的成烃机制,据地球化学研究认为,稠油是次生成因的,原油来源于上古生界生油岩,原油分成三种类型, 1类原油为“早期成烃”机制的产物,I类原油为“晚期成烃”机制的产物,1类原油为过渡类型。西北艨巳棵明和开发的原油绝大部分为I类原油。

Abstract: Based on geochemistry studies of oil geneses and cr ude hydrocarbon-formed mechanism in northwestern marginof Junggar Basin, it has been considered that origin of the heavy oil should be secondaiy in nature and emerged fromUpper Paleozoic source rocks. This oil can be classified into three types: type I is the product of "eatly formed hydro-carbon mechanism type II is the product of late formed hydrocarbon mechanism;type III is a transition one. Themost crude oil that prospected and developed in the northwestern margin is type I in nature.
