摘 要：
通过运用色谱-质谱分析技术,系统剖析了马家嘴油田原油饱和烃地球化学特征。正构烷烃的微弱双峰型以及规则甾烷"V"字型的分布特征说明母质为低等水生藻类和高等陆源植物的混合来源;姥植比介于0.73~0.83,伽马蜡烷/C30藿烷介于0.37~0.45,三环萜烷系列化合物以C23为主峰正态分布,表明其源岩形成于微咸水-半咸水湖相环境;各成熟度参数的比值表明研究区的原油属于低熟-成熟原油。

摘 要：
The geochemical characteristics of saturated hydrocarbon from the oil of Majiazui oilfield are systematically analyzed by GC-MC.The results show that n-alkanes with weak bimodal distribution and regular sterane with"V"shape distribution indicates that the organic source is from the lower aquatic algae and the higher terrestrial plants.The Pr/Ph is ranged from 0.73to 0.83,the G/C30His ranged from 0.37to 0.45and distribution of the main peaks of tri-cyclic terpanes of nC25shows that source rocks are developed in brackish and saltwater reductive environment.According to the ratio of the maturity parameters,it is presented that the oils belong to the low mature-mature oils.
