摘要

页岩气具有“原地”成藏的特征,主要发育在高有机质含量的泥页岩中。在海相沉积地层中,这些优质的泥页岩主要发育在被动大陆边缘盆地、克拉通内坳陷盆地和前陆盆地这3类盆地中。沉积相主要分为陆棚相和海陆过渡相。页岩气勘探与以往油气勘探思路和模式有着显著的不同,探讨了以盆地类型控制选区,以有机相优选区带,以残余有机碳含量、有机质成熟度、泥页岩厚度和泥页岩埋深约束勘探目标,以泥页岩脆性、泥页岩层温度和压力系统、地层沉降史、原地含气量等约束“甜点”位置的页岩气勘探选区模型,并结合中上扬子地区下寒武统的现有油气地质条件,认为湘鄂西地区是最为有利的页岩气勘探区域。

Abstract

Shale gas mostly develops in shale of high TOC forming reservoir “in place”. These top quality shale mostly grow in shelf facies and marine\|continental transitional facies in passive margin basin, intracratonic basin and foreland basin. The exploration of shale gas is different from the conventional oil and gas. This paper discusses the model for selecting shale gas region mainly by basin types and organic facies. The favorable target is controlled by TOC, organic matter maturity, the thickness and deepness of shale. The brittleness of shale,stratum subsidence history, temperature and pressure of the stratum and gas content in place etc constraint the location of “favorable target”, On the basis of the understanding about lower Cambrian strata in middle and upper Yangtze, it is concluded that western Hunan and Hubei Beidafang tectonic province in north\|west of Guizhou and the area of Weiyuan is the he most favorable exploration area.
