Abstract

The natural gas and crude oil from Xuwen X1 well Maichen sag,Beibuwan basin,have been analyzed and the results show that the natural gas is of lower methane content,higher content of heavy hydrocarbon gas and lower dryness coefficient.It is a typical oil-type gas because of lighter carbon isotope(-30‰) for ethane and propane.As for the crude oil, its tricyclic terpane series with steplike style(C_(19)>C_(20)>C_(21)>C_(23)>C_(24)>C_(25)>C_(26))looks like coal-derived oil.However,high content of C_(27)sterane.

Key words： Beibuwan basin; Maicheng sag; Natural gas; Crude oil; Stable carbon isotope; Biomarkers.
