摘要： 根据准噶尔盆地东部三台地区(含北三台南段和吉木萨尔凹陷及其南缘)原油的轻烃对比星图,原油饱和烃m(Pr)lm(Ph)值、β-胡萝卜烷含量特征,三类规则甾烷的组成、妊甾烷的含量特征及其成熟度指标,三、四环萜垸和γ-蜡烷的组成特征,以及应用原油二环倍半萜的重排补身烷与8β (H)-补身烷的比值及4.4,8,8,9-五甲基+氢化萘(PMDHN)与4,4,8,9,9-PMDHN的比值和C30藿烷及菲、甲基菲化合物等的组成可将本区原油从成因上分为3类,第1类源于中二叠统平地泉组-芦草沟组烃源岩.为本区的主体原油;第2类则源于侏罗系烃源岩;第了类源于石炭系巴塔玛依内山组烃源岩。源于二叠系的原油其油源区从东到西分别为吉木萨尔凹陷、天山山前凹陷和阜康凹陷,侏罗系原油则主要源于阜康凹陷的侏罗系烃源岩,而源于石炭系的原油其油源区在工区内部。

Abstract: Santai crude oil can be classified into three types based on light hydrocarbon stellar diagram, m(Pr)/m(Ph) of saturated hydro-carbon, content characteristics of β-cartane, composition of three types of regular steranes, content characteristics of pregnane and maturity index, composition characteristics of triterpene-tetracyclic terpane and gammacerane of crude oil in Santai area of Junggar basin, and based on rearanged drimanes/8B(H)-drimanes ratio, 4,4,8,8,9-PMDHN/4,4,8,9,9-PMDHN ratio of bicyclic sesquiterpenes and compoaition of C30-hopane, phenanthrene and metylic-phenanthrene in crude oil. The first-type crude oil, the major crude oil in Santai area, is original-ed from source rocks of Pingdiquan-Lucagou formnation of Middle Permian. The second -type crude oil is from source mocks of Jurassic. The third-type crude oil is from those of Carboniferous Batamayineishan formnation. The Permian crude oil comes from Jimusaer seg, Tianshan mountain front seg and Fukang seg. The Jurassic crude oil comes from Jurassic source rocks in Fukang seg, while Carboniferous crude oil is just from this studied area.
