摘要：

页岩气的勘探表明，页岩含气已成为一个不争的事实，但是含气的规模以及是否具有工业价值需要进一步研究。与美国相比，中国页岩气具有独特的地质条件，页岩气保存条件可能是中国南方下古生界页岩气勘探研究的重点。文中以四川盆地及其周缘下古生界下寒武统和上奥陶统—下志留统页岩层系为研究对象，从物质基础、构造作用和演化历史、地层水条件、盖层及其微观性质、天然气组分和压力系数等几个方面对页岩气的保存条件进行研究，并综合分析各种指标，提出页岩气保存条件综合评价指标体系，以期对四川盆地及其周缘下古生界页岩气勘探提供更进一步的参考资料。

Abstract:

The exploration of shale gas indicated an indisputable fact that there is gas in shale, but the size of the shale gas reservoir and its industrial value need further study. Compared to the high production of U.S. shale gas, shale gas has its peculiar geological characteristics in China. The shale gas preservation conditions may be the focus of the shale gas exploration in China, which is less studied in U.S. shale gas exploration. This paper studied the shale gas preservation conditions by material basis, tectonism, evolutionary history, hydrogeology, seal and its microscopic properties, gas composition, pressure coefficient and other parameters of shale in the Lower Cambrian and the Upper OrdovicianLower Silurian of the Lower Paleozoic in Sichuan Basin and its periphery. The evaluation system of shale gas preservation of south China was put forward by comprehensive analysis of various parameters.
