Open publisher page 1 citations

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.
