摘要： 元坝气田长兴组生物礁(滩)相天然气藏是川东北地区近期勘探的热点。采用流体包裹体显微荧光技术和测温技术,结合IES(Integrated Exploration Systems)软件模拟的埋藏史和热演化史,对该区油气充注时间和成藏期次进行了研究。结果表明,元坝地区长兴组生物礁储集层大致经历了晚三叠世和晚三叠世–早白垩世2 期原油充注。烃源岩生烃高峰与原油充注时间的高度匹配是元坝气田成藏的重要因素之一。

Abstract: 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.

Key words: Sichuan basin, Yuanba gas field, Yuanba area, Changxing formation, fluid inclusion, charge history
