摘要
为解决六盘山盆地白垩系马东山组生烃潜力不明、烃源岩演化不清等问题,依据岩心有机地球化学分析测试数据,对宁固参1井烃源岩的有机质丰度、类型、成熟度进行了研究,评价了马东山组烃源岩的生烃潜力。结果表明:马东山组烃源岩有机质丰度中等—低,类型主要为Ⅱ2型和Ⅲ型,热演化程度处于低成熟—成熟阶段,以生油为主。该研究结果对六盘山盆地的烃源岩地球化学特征、生烃潜力评价、预测油气有利区具有指导作用。
In order to figure out hydrocarbon-generating potentials and evolution for the source rocks of Madongshan Formation of Cretaceous in the Liupanshan Basin,the organic geochemical data of core samples were presented to further analyze the abundance,type,maturity of organics and evaluate the hydrocarbon-generating potentials of ninggucan1 well.The results show that the source rock is characterized by medium-low hydrocarbon-generating potential with moderate-low abundance of organics,Ⅱ2 to Ⅲ type and low-mature stage.This study is helpful for guiding the evaluation of geochemical characteristics and hydrocarbon-generating potentials of source rocks,as well as the prediction of favorable oil and gas areas in the Liupanshan Basin.
