| Abstract: | Organic petrology is a new and marginal science that is quite practicable. At present, it has been developed into the routine research tool that is widely applied in petroleum exploration and assessment. Based on several years' research of the authors, this paper presents an overview of the advances in organic petrology of the immature source rocks, including the classifications and characteristics of macerals, and the composition of macerals and types of organic matter, the abundances and evolutions of organic matter, oil prone macerals, hydrocarbon generation and explosion. All these results show that organic petrology is of a good application value in the assessment of immature oil and gas. The immature source rocks consist of various macerals with obvious heterogeneity, contain different hydrocarbon generated macerals with different oil threshold and peak, and appear as a two staged evolutionary pattern of organic matter. |
