摘要
Yuanba gas field with biohermal reservoir is one of the most popular regions for recent exploration in northeastern Sichuan Basin. By means of fluid inclusion microfluorometric and thermodetecting techniques, combined with the burial and geothermal evolution history of the source rock simulated by IES (Integrated Exploration Systems) software, this paper proposes two-stage oil charge of Late Triassic and Late Triassic-Early Cretaceous in biohermal reservoir of Changxing Formation in Yuanba area. The oil charge time is well accordant with the oil-generating peak of the source rock, which is one of major factors for hydrocarbon accumulation of Yuanba gas reservoir.
