摘要
中国已发现的生物气藏分布于第四系-白垩系,埋深小于2000m,生物气藏类型比较简单,生物气生成和聚集在未成熟源岩发育段,储层物性好,生物气成藏类型可划分为3种,低温-同生成岩-浅埋型,中温-早成岩A期-中深埋型,高温-早成岩B期-深埋型。
Biogenic gas pools discovered in China are stored in Quaternary-Cretaceous. Their pool types are simple and the buried depth is less than 2000m. The biogenic gas is generated and accumulated during immature stages, with good reservoir quality. The pool-forming types of biogenic gas can be divided into three types: low temperature-syngenetic diagenesis-shalow burial type,middle temperature-early diagenesis A stage-medium burial type and high temperature-early diagenesis B stage-deep burial type.
