页岩不生气,和致密砂岩一样只能作为储层。阿巴拉契亚盆地盆地志留系和泥盆系致密砂岩气显示完全的碳同位素反序(δ13C1>δ13C2>δ13C3),它的幔源特征证明了紧邻致密砂岩层之下的页岩层中的天然气同样来源于地幔。所谓“吸附式成藏模式”、“活塞式成藏模式”与有机成因一样,非但毫无根据的,并且实践上将油气勘探开发引向歧途。 Shale is not angry, and can only be used as a tight sandstone reservoir. The Silurian and Devonian tight sandstone gas in the Appalachian basin show complete carbon isotopic reverse sequence (δ13C1> δ13C2> δ13C3), and its mantle source features have demonstrated that the tight sandstone in the shale immediately below the tight sandstone Natural gas also comes from the mantle. The so-called “adsorption accumulation model ”, “piston accumulation model ” and organic causes, not only without foundation, and in practice will be the exploration and development of oil and gas to the wrong path.
