摘要：

湘鄂西地区因与威远气田具有类似的下古生界系统,可对比的早期沉降、晚期抬升的地质过程而被认为有良好油气前景。然而,湘鄂西地区的抬升幅度过大,超压系统已不复存在且无古构造控制油气的早期聚集,所以该区除秭归复向斜尚可进一步勘探外,其他地区应持慎重态度。

关键词: 威远气田, 类比, 抬升, 压力系统, 古构造, 湘鄂西

Abstract:

The western Hunan and Hubei area have been considered to have nice prospects due to its lower Paleozoic is similar to that in Weiyuan gasfield,and has also experienced similar geologic process of early subsidence and intensive late uplifting in later stage. However,the overpressure system is no longer present in western Hunan and Hubei area,because the uplifting amplitude has been too large and the lack of favorable paleostructure controlling early hydrocarbon accumulation.Therefore,the hydrocarbon exploration in this region should be cautious,but a further exploration is required in Zigui synclinore.

Key words: Weiyuan gasfield, analogy, uplift, pressure system, paleostructure, western Hunan and Hubei area
