【摘要】：為評價南祁連盆地木里坳陷油氣勘探潛力,利用木參1井分析化驗資料,對木里坳陷烴源條件與勘探潛力進(jìn)行了系統(tǒng)分析。結(jié)果表明,上三疊統(tǒng)尕勒得寺組(T_3g)和侏羅系暗色泥巖發(fā)育,侏羅系也發(fā)育碳質(zhì)泥巖和煤。T_3g和侏羅系的暗色泥巖有機(jī)質(zhì)豐度高,綜合評價為中等-好烴源巖;T_3g烴源巖的有機(jī)質(zhì)類型為Ⅲ型和Ⅱ2型,侏羅系烴源巖有機(jī)質(zhì)類型多樣,主要為Ⅲ型和Ⅱ型,部分暗色泥巖有機(jī)質(zhì)類型為Ⅰ型。T_3g和侏羅系烴源巖有機(jī)質(zhì)分別處于高-過成熟的生氣階段和成熟階段;2套烴源巖均經(jīng)歷了二次生烴,烴源巖的熱演化過程在流體包裹體數(shù)據(jù)中得到了較好地反映;初步計算結(jié)果顯示木里坳陷油資源量為1140×10~4 t,天然氣資源量為(545~2180)×10~8 m~3,具備較大的勘探潛力。
[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，
