摘要:
哈日凹陷下白垩统发育多套湖相暗色泥岩,各组烃源岩对该区油气勘探具有重要意义。文中利用钻井及岩心分析化验资料,研究了下白垩统各组烃源岩特征,通过开展岩石热解、干酪根显微组分、镜质体反射率、可溶有机质组分及饱和烃色谱-质谱等有机地球化学测试和分析,评价了银根组、苏红图组和巴音戈壁组的烃源岩有机质丰度、类型和成熟度,认为银根组烃源岩属低成熟、偏腐泥型、好烃源岩、苏红图组烃源岩属成熟、腐泥-腐殖混合型、差-中等好烃源岩、巴音戈壁组烃源岩属成熟-高成熟、腐泥-腐殖混合型、中等-好烃源岩,进而分析其生烃潜力,其中银根组生烃潜力最大,其次为巴音戈壁组,苏红图组相对较差,预测哈日凹陷下白垩统总油气资源量为1.13×108 t.
Abstract:
Mutiple lacutrine dark mudstones were developed in the Lower Cretaceous of Hari Sag. The source rocks of each group are greatly significant to oil and gas exploration in Hari Sag of Yin'gen-Ejinaqi Basin,the characteristics of source rocks in the Lower Cretaceous were studied,using drilling and core analysis data,the organic geochemical tests and analysis methods concluded rock pyrolysis,kerogen microstructure,vitrinite reflectance,soluble organic matter and saturated hydrocarbon chromatography-mass spectrometry. Based on these,abundance,type and maturity of the source rocks organic matter were evaluated in Yin'gen,Suhongtu and Bayin'gebi Formation. It was revealed that the source rocks of the Yin'gen Formation were low mature,partial-sapropel model and good type. The source rocks of Suhongtu Formation were mature,saprophytic-humic mixed,poor-medium good type. And the source rocks of Bayin'gebi Formation were mature-highly mature,saprophytic-humic mixed,medium-good type. In the end,the hydrocarbon potential was analyzed. The results showed that the highest hydrocarbon potential Formation was Yin'gen Formation. The second one is the Bayin'gebi Formation and Suhongtu Formation was relatively poor. The total oil and gas resources of the Lower Cretaceous were predicted to be 113 million tons in Hari Sag.
