| 摘 要： | 利用天然气组成与碳同位素(C1～4)、轻烃(C4～8)、中分子量烃(C8～20)以及油岩生物标志化合物(>C15)全烃地球化学方法,按照油气分段捕获原理,确定了泸州古隆起嘉陵江组烃源,并建立了相应的烃源模式.研究表明该区嘉陵江组油气与自身烃源无关,主要来源于下伏烃源层,存在多期多源烃类注入,而且不同区域烃源贡献大小不同,其中古隆起核部和核部边缘以志留系烃源为主.

| Abstract: | In this paper, based on the mechanism of oil - gas fraction entrapment, the hydrocarbon sources in Jia Lingjiang Formation of the Luzhou Paleohigh has been confired by the whole - hydrocarbon geochemistry method which is the natural gas composition together with the carbon isotope ( C1-4 ) ,and light hydrocarbon (C4-8),and middle molecular weight hydrocarbon (C8-20) and the oil - rock biomarker ( > C15 ). Moreover, the relevant hydrocarbon source pattern has been established. The research results have suggested that oil - gas in Jia Lingjiang Formation has nothing to do with against itself hydrocarbon source, mostly comes from Hydrocarbon source stratum below it, that is the characteristics of much stages and sources. But the hydrocarbon source capacities varies from different area. For instance, the Silurian hydrocarbon source mainly distributes in the Center and its edge of the Luzhou Paleohigh. |
