摘要
应用原油、天然气及烃源岩样品有机地球化学资料,对准噶尔盆地呼图壁气田油气地球化学特征及成藏时间进行分析.研究表明,呼图壁气田原油来源于白垩系烃源岩,天然气来源于侏罗系煤系烃源岩干酪根裂解气,源岩大量生气始于12 Ma左右,天然气成藏时间约在5 Ma.
Application of crude oil,natural gas and hydrocarbon source rocks of the organic geochemical data, analysis oil gas geochemistry characteristic and accumulation time of Hutubi gas field in the Junggar Basin. The results show that Hutubi gas field crude oil originates from the Cretaceous system hydrocarbon source rock,the natural gas is the Jurassic series coal formation hydrocarbon source rock kerogen decomposition, the source rock massive vitalities begin in about 12Ma, the natural gas reservoir formation time evening, reservoir formation time approximately about 5Ma.The reason natural gas＇s exploration should seek for the 5-12Ma time production consciously with emphasis the natural gas in South of the Junggar Basin.
