摘　　要：南祁连盆地广泛发育上三叠统尕勒德寺组泥质岩类烃源岩,但其有机质丰度、类型、热演化程度及油气运移聚集的研究程度很低,从而对木里坳陷尕勒德寺组烃源岩进行综合评价。结果表明,有机质丰度为中等-好烃源岩级别,有机质类型为腐泥腐殖型(Ⅱ2),有机质到达高成熟—过成熟阶段。整体评价为中等烃源岩。The hydrocarbon source rock of upper Triassic Galedesi Fomation mudstone Widely distribute in the South Qil- ian Basin, but the research level on the organic matter abundance, type, maturity and hydrocarbon migration and accumulation is very poor. Therefore, it is extremely necessary to integratedly eveluate the hydrocarbon resources in the area. The results through the integrated evaluation of hydrocarbon source rock of Galedes Fomation in the Muli Depression indicated that ： the organic matter abundance is medium - good, type is sapropelic - humic（Ⅱ 2） and at the high - over mature stage. It is finally eveluated as medium hydrocarbon source rock.
