摘要

摘要: 世界许多地方都发现了未成熟油,然而,其形成机理尚未完全搞清.目前有5种以上的观点解释未成熟油的成因.事实上,大部分未成熟油有着相似的特征,所以它们很可能主要是由相似的方式形成的,文中报道了利用江汉盆地(源岩)钙质泥岩、绿河页岩、抚顺油页岩和南宁褐煤样品(采自岩心或矿场)所做模拟实验的结果.在较低温度条件下,由这些样品分离出的干酪根形成的饱和烃与成熟油相似,而全样(包括干酪根和可溶有机质)形成的饱和烃与未成熟油非常相似.这就证明了未成熟油可能主要是由沉积物中原生可溶有机质直接转化而成的.

Abstract: Immature crude oils were found in many places of the world,but their formation mechanism has not been understood clearly.There are now more than five viewpoints on the origin of them.In face,most of immature oils have similar characters,so it is very possible that they were mainly formed by similar ways.In this paper,the results of simulation experiments on Jianghan calcareous mudstone,Green River shale,Fushun oil shale and Nanning lignite samples(collected from cores or orefields)were reported.Under the condition of lower temperature,the saturated hydrocarbons formed by kerogen from these samples are similar to mature oils,and those formed by bulk samples(including kerogen and soluble organic matter)are very similar to immature oils.This proved that immature crude oils possibly are mainly converted directly from primary souble organic matter in sediments.
