【摘要】 本文着重探讨生物化学作用阶段有机质的结构组成特征、早期演化规律，研究该阶段微生物的作用，指出生化阶段有机质演化的主要营力是微生物作用。其作用既破坏和消耗了有机质，也造成了贫氧环境，使有机质得以保存，并促进有机质向烃类转化。认为未成熟有机质与成熟有机质显然有差异；建立了生化阶段有机质演化程度的判别标志。更多还原

【Abstract】 This paper emphasices on the discussion of the structural characteristics and early evolution regularities in biochemical reaction stage, and the action of microrganisms has been studied. It points out that microbial activity is the main action in this stage. The main action is to destroy and consume organic matters and an anerobic environment will be form as a result. Thus, organic matter can be preserved and a evolution of organic matter foward hydrocarbons will result. It is suggested that unmatured organic matter has characteristics differ from those of matured ones.更多还原
