摘要

乌夏断裂带是准噶尔盆地西北缘重要的控藏断裂,油气赋存于二叠系、三叠系等层系,原油性质复杂。针对二叠系与三叠系原油显著的组分差异,基于原油物理性质、全油族组成、饱和烃及生物标志物分析,对2套原油的特征进行了系统地评价与对比。研究发现:2套原油均为成熟轻质油,物理性质相似,但在地球化学特征上存在显著差异。二叠系原油富含β-胡萝卜烷和伽马蜡烷,指示藻类母质源自强还原、高盐度湖泊环境;三叠系原油生物标志物显示以藻类为主、混有高等植物的混合母质,形成于弱还原—氧化湖泊环境。油源对比证实,二叠系油藏主要接受二叠系风城组供烃,三叠系油藏为风城组与乌尔禾组混源产物。该认识阐明了乌夏断裂带不同层系油藏的成因差异,为该区域后续油源追踪、精细勘探及有利目标优选提供了重要地球化学依据。

Abstract

The Wuxia fault zone is an important reservoir-controlling fault in the northwestern margin of the Junggar Basin.Its oil and gas reservoirs occur in strata such as the Permian and Triassic and the crude oil properties are complex.Aiming at the significant compositional differences between Permian and Triassic crude oils,the characteristics of the two sets of crude oils were systematically evaluated and compared based on the analysis of physical properties,whole oil group composition,saturated hydrocarbons and biomarkers of the crude oils.Research findings indicate that both sets of crude oils belong to mature light oil and have similar physical properties,but exhibit significant differences in geochemical characteristics.Permian crude oil is rich in β-carotane and gammacerane,indicating algal organic matter originating from a strongly reducing,high-salinity lacustrine environment;biomarkers of Triassic crude oil show mixed organic matter dominated by algae with higher plants,formed in a weakly reducing-oxidizing lacustrine environment.Oil-source correlation confirmed that Permian oil reservoirs mainly received hydrocarbon supply from the Permian Fengcheng Formation,while Triassic oil reservoirs are a mixed-source product of the Fengcheng and Urho Formations.This understanding clarifies the genetic differences of oil reservoirs in different strata of the Wuxia fault zone and provides an important geochemical basis for subsequent oil-source tracing,refined exploration,and favorable target optimization in this area.

Key words： biomarker compounds; crude oil origin; oil-source correlation; Wuxia fault zone; Junggar Basin
