摘　　要：准噶尔盆地腹部莫北—莫索湾地区原油成因类型复杂,通过混源油配比模拟实验,发现原油的一些生物标志物组成随混源油比例呈现有规律的变化,因而可能是判识原油成因类型的有效指标。据此,综合原油的其它地球化学参数,将本区的原油分出4种成因类型。根据这些不同类型原油的区域分布特点,结合地质背景,分析了原油的运聚特征。研究结果为区域油源与成藏研究提供了有益的参考信息。Origin of oils in the Mobei-Mosuowan area of the central Junggar Basin is complex.In order to reveal this complexity,genetic types of the oils were classified in this paper,and their migration and accumulation was discussed.Based on artificial oil mixing experiments,it is found that some biomarker compositions of oils show regularities along with mixing ratios of oils.Thus,these representative biomarkers may be criteria for determining origin of mixed oils.According to the criteria,oils in the area were divided into four types.Migration and accumulation of the four type oils were further discussed,combined with geological backgrounds.Thus,this paper provides valuable information for the study of regional oil source and formation.
