众所周知,不同类型干酪根的成烃潜力有很大差别,且产物性质也有所不同。因此,在油气资源的评价中,正确判别干酪根的类型有着十分重要的意义。1982年,我们曾在“干酪根类型划分的X图解”一文中,在法国石油研究院分类的基础上,利用岩石热分析(ROCK-EVAL)资料把干酪根划分为三类五型,即标准腐泥型(Ⅰ_1),含腐殖的腐泥型(Ⅰ_2),中间型或混合型(Ⅱ),含腐泥的腐殖型(Ⅲ_1)和标准腐殖型(Ⅲ_2)。与此相应,我国陆相沉积盆地的油源区,按主力油源层的干酪根类型,基本上可以分为五大类:
As we all know, different types of kerogen hydrocarbon generation potential are very different, and the product properties are also different. Therefore, in the evaluation of oil and gas resources, the correct identification of kerogen type is of great significance. In 1982, we classified the kerogens into three types and five types based on the ROCK-EVAL data on the basis of the classification of the French Petroleum Institute in the article “X-Diagram of Kerogen Type Division” Sapropel type (Ⅰ_1), humic type sapropel type (Ⅰ_2), intermediate type or mixed type (Ⅱ), sapropelic humic type (Ⅲ_1) and standard humic type (Ⅲ_2). Correspondingly, the oil source areas of the continental depositional basins in China can be basically divided into five major categories according to the kerogen types of the main oil source layers:
