摘要： 为解决柴达木盆地干柴沟地区下干柴沟组上段（E32）烃源岩评价标准尚未建立、烃源岩研究程度偏低的问题,通过大量岩心化验分析进行有机岩石学、有机地球化学、正构烷烃及类异戊二烯烷烃为代表的生物标志化合物研究,对干柴沟地区下干柴沟组上段进行了烃源岩评价及母质沉积环境探讨。结果表明：依据烃源岩有机质类型、TOC、氯仿沥青“A”含量、游离烃S1指标可确定Ⅰ、Ⅱ、Ⅲ类烃源岩的评价标准;烃源岩有机质来源为藻类等低等水生浮游生物和微生物;有机质类型为Ⅱ1-Ⅰ型;烃源岩成熟度介于低成熟-成熟生烃阶段。该研究对确定下一步有利勘探目标具有一定的指导意义。

Abstract: In order to solve the problem that the evaluation standard of source rocks in the upper Member of the lower Ganchaigou Formation （E32） in Ganchaigou area of Qaidam Basin has not been established yet and the research degree of source rocks is low, the source rocks and parent material sedimentary environment of the upper Member of the lower Ganchaigou Formation in Ganchaigou area are evaluated by studying biomarkers such as organic petrology, organic geochemistry, n-alkanes and isoprene-like alkanes through a large number of core analysis. The results show that according to the organic matter type, TOC, chloroform asphalt "A" and free hydrocarbon S1 index of source rocks, the evaluation criteria of class Ⅰ, Ⅱ and Ⅲ source rocks can be determined. The organic matter of source rocks comes from lower aquatic plankton and microorganisms such as algae. The type of organic matter is Ⅱ1-Ⅰ. The maturity of source rocks is between low maturity and maturity. This study has certain guiding significance for determining favorable exploration targets in the next step.

Key words: hydrocarbon source rock, geochemical characteristics, biomarkers, lower Ganchaigou Formation, Ganchaigou area, Qaidam Basin
