摘要: 通过分析墨西哥湾盆地油气资源勘探现状、油气地质特征,及与油气成藏密切相关的盐岩形成、演化和分布特征,进一步认识到墨西哥湾盆地上侏罗统牛津阶—第四系更新统发育了4套优质烃源岩和多套性能优越的储集层,封堵性能良好的局部和区域盖层遍布整个新生界层系,断层提供了运移通道,构造和地层圈闭发育,具有优越的生储盖等油气成藏条件。盆内中侏罗统发育一套广泛分布的厚层盐岩,很多大型油气藏均与该盐岩相关。盐上和盐下储层中均有可观的油气发现,随着油气勘探理论和技术的进步,盐下油气藏的潜力逐渐显现出来,勘探潜力很大。Abstract: The hydrocarbon exploration conditions and geologic features of the Gulf of Mexico Basin were studied, and the formation, evolution and distribution of salt deposits which were closely related to the reservoirs were analyzed. From the Oxfordian Stage of the Upper Jurassic to the Pleistocene Series of the Quaternary, four sets of excellent hydrocarbon source rocks and various favorable reservoirs developed. Effective sealing formations were widespread in the Cenozoic. Faults provided pathways for hydrocarbon migration. Structural and stratigraphic traps were common. All these contributed to the generation and preservation of hydrocarbon. Thick salt deposits were widespread in the Middle Jurassic of the basin, which had a close relationship with giant oil and gas pools. Major discoveries have been made in both pre-salt and post-salt formations. As petroleum exploration theory and technique advanced, the pre-salt formations in the deepwater area of the basin attracted more attention and showed good potential.
