摘要：

江汉盆地是一个比较典型的中新生代陆相盐湖盆地。它的特定的高盐度、强还原性地质环境使下第三系生油岩及原油有其特殊性。本文试图利用通过红外、紫外、荧光、色谱-质谱等多种手段分析江汉盆地生油岩及原油(以潜江凹陷潜江组为主)而取得的有关卟啉、菲、萜烷、甾烷等生物标记化合物的资料,结合过去取得的镍、钒等分析结果,进一步总结盐湖盆地生油岩及原油的特征,并据此对沉积环境、原油及生油岩的演化程度以及油源对比等问题,进行初步探讨。

Abstract:

Steroids,terpanes,porphyrins and perylenes etc. from source rocks and crude oil of Lower Tertiary (Eocene)in Jianghan basin are analyzed by means of IR,UV,UVF and GC-MS etc. Characteristics of source rocks and crude oil as well as sedimentary environment,maturity of source materials,oil migration and types of organic matters of the basin are discussed. According to the study of biological mark compounds and systematic molecular parameters,the authors suggest that:(1) The oil source of the Qianjiang Formation is different from that of the Xingouzui Formation;(2) Though the buried depth of Xingouzui reservoir is shallow,it has a high maturity;(3) Oil-generating threshold in the Qianjiang Formation is about 1900m;(4) The presence of gammacerane is typical of the continental organic source material.
