| 摘 要： | 柴达木盆地北缘马北地区不同构造上的原油分两大类。一类是该地区普遍分布的原油,包括马北1 井、马北101 井和马北3 井以及马北2 井后期注入的原油,这类原油主要来源于中侏罗统烃源岩,但在成熟度上存在显著差异: 马北1 井浅层和马北3 井原油来源于尕丘凹陷,属成熟原油; 马北1 井深层和马北101 井原油来源于赛什腾凹陷,为高成熟原油。另一类是马北2 井生物降解原油,来源于石炭系海陆交互相烃源岩。

| Abstract: | Two kinds of crude oils occur in the different structures in Mabei area in northern margin of Qaidam basin. One is the oil broadly distributed in this area, including Mabei-1 Well, Mabei-101 Well, Mabei-3 Well and late filled oil in Mabei-2 Well. Such oils mainly originated from the source rocks of Middle Jurassic with distinction of maturity. The oil from shallow layer in Mabei-1 Well and Mabei-3 Well originated from Gaqiu sag, belonging to matured oil; while the oil from deep layer in Mabei-1 Well and Mabei-101 Well originated from Saishiteng sag, being highly matured oil. The other, biodegraded oil, was found in Mabei-2 Well, originating from transitional facies source rocks of Carboniferous in this area. |
