摘要
根据南堡凹陷第三系地层水中 HCO_3^-离子的碳同位素值,可以将地层中甲烷菌的发酵阶段分为:发酵初期,发酵高峰期,发酵衰落期,甲烷菌死亡线和甲烷菌化石期五个阶段。甲烷菌发酵阶段理论可以指导生物气藏的地质勘探,以提高勘探效率。
Based on carbon isotopes of HCO^-_3in the Teriary formation water located in the Nanpu depression in Hebei province,methanobacteria fermentation can be divided into five stages as following:primary,maximum,decline,dead line and fossilization of the bacteria.The classifi- cation of fermentation stages,which determinated by this study,can be used to help the ex- ploration and development of biogenic gas in the future.
