内蒙古拉布达林盆地烃源岩有机地球化学特征
|
摘要
在野外地质勘查、典型剖面实测、样品采集及实验分析基础上,对拉布达林盆地潜在的烃源岩的有机质丰度、类型、成熟度等有机地球化学特征进行了分析评价.结果表明:1)上石炭统新伊根河组有机碳含量和生烃潜力均较低,有机质类型为I型,普遍达到到高成熟—过成熟阶段,为差烃源岩;2)中侏罗统万宝组有机碳含量中等,生烃潜力偏低,有机质类型为I型和II_1型,处于低成熟阶段,为中等—差烃源岩;3)上侏罗统满克头鄂博组有机碳含量中等,生烃潜力较好,有机质类型为II1型,处于低成熟阶段,为较好烃源岩;4)下白垩统大磨拐河组有机碳含量较高,生烃潜力较好,有机质类型为为II_1型和II_2型,处于低成熟—成熟阶段,为好烃源岩.
The organic geochemical analysis and evaluation on abundance,types and maturity of organic matters in potential source rocks of Labudalin Basin are conducted on the basis of geological exploration,typical profile survey,sampling and experiment. The results show that the TOC and hydrocarbon potential of Upper Carboniferous Xinyigenhe Formation are both low,with I-type organic matter generally reaching the high-mature to post-mature stage,ranked as poor source rock. The TOC of Middle Jurassic Wanbao Formation is medium,with low hydrocarbon potential,I-and II_1-type organic matter in low-mature stage,belonging to poor to medium grading. The TOC of Upper Jurassic Manketouebo Formation is medium,with good hydrocarbon potential,II_1-type organic matter in low-mature stage,belonging to fair grading. The TOC of Lower Cretaceous Damoguaihe Formation is high,with good hydrocarbon potential,II_1-and II_2-type organic matter in low-mature to mature stage,belonging to good grading.
