【摘要】:为评价南祁连盆地木里坳陷油气勘探潜力,利用木参1井分析化验资料,对木里坳陷烃源条件与勘探潜力进行了系统分析。结果表明,上三叠统尕勒得寺组(T_3g)和侏罗系暗色泥岩发育,侏罗系也发育碳质泥岩和煤。T_3g和侏罗系的暗色泥岩有机质丰度高,综合评价为中等-好烃源岩;T_3g烃源岩的有机质类型为Ⅲ型和Ⅱ2型,侏罗系烃源岩有机质类型多样,主要为Ⅲ型和Ⅱ型,部分暗色泥岩有机质类型为Ⅰ型。T_3g和侏罗系烃源岩有机质分别处于高-过成熟的生气阶段和成熟阶段;2套烃源岩均经历了二次生烃,烃源岩的热演化过程在流体包裹体数据中得到了较好地反映;初步计算结果显示木里坳陷油资源量为1140×10~4 t,天然气资源量为(545~2180)×10~8 m~3,具备较大的勘探潜力。
[Abstract]:In order to evaluate the hydrocarbon exploration potential of Muli depression in South Qilian Basin, the hydrocarbon source conditions and exploration potential of Muli depression were systematically analyzed by using the analysis and test data of well Mushen 1. The results show that the upper Triassic Galerdsi formation and Jurassic dark mudstone are developed, and the Jurassic system also has high organic abundance of carbonaceous mudstone and coal. T3g and Jurassic dark mudstone. The organic matter types of T _ 3g source rocks are of type 鈪,
