摘要： 近年来,塔里木盆地库车坳陷勘探取得重大突破,但前人对于研究区的油气成藏过程研究比较薄弱.本文利用有机地球化学、流体包裹体等实验,结合盆地模拟技术,系统分析研究区原油来源、成藏期次和成藏过程.结果表明,研究区存在Ⅰ和Ⅱ两类原油,I类英买力原油的三环萜类总体具有C19C22C20>C21>C22

Abstract: In recent years,significant breakthroughs have been achieved in the exploration of the Kuqa Depression in the Tarim Basin.However,previous studies on the hydrocarbon accumulation process in the study area are relatively scarce.In this study,organic geochemistry,fluid inclusion experiments,and basin simulation techniques are employed to systematically analyze the source,accumulation period,and accumulation process of crude oil in the study area.The results show that two oil groups,namely Group Ⅰ and Group Ⅱ,can be identified in the study area.The tricyclic terpenoids of Group Ⅰ crude oil follow the pattern of C19C22C20>C21>C22
