Abstract

Abstract:

In this study, 37 samples of Lower Cambrian shale collected from different sections involving shale gas exploration-breakthrough areas (Well WPZK001 from Yichang City, Changyang section from Hubei Province, and Well W001-4 from Weiyuan County) and -failure areas (Kaiyang section from Guizhou Province and Youyang section from Chongqing City) both in the Middle-Upper Yangtze region were investigated by water uptake experiments, with a similar comparative study of Silurian Longmaxi shale samples in the Sichuan Basin. The comparative results showed that the water uptake content for the Lower Cambrian organic-rich shale samples from shale gas exploration-breakthrough areas are primarily controlled by TOC content, showing a positive correlative increase of water content and TOC content, which is similar to that of Silurian Longmaxi organic-rich shale samples in the Sichuan Basin. In contrast, the water uptake content for the Lower Cambrian organic-rich shale samples from shale gas exploration-failure areas generally showed a positive correlation with clay and carbonate contents, and there is no correlation with TOC content. It implies that the characteristics of pore network in the Lower Cambrian organic-rich shales from Middle-Upper Yangtze region, especially the development of organic matter-hosted pores, display significant differences regionally. Importantly, it provides a newly-developed strategy on the study of gas content variation in Cambrian shale from Middle-Upper Yangtze region by investigating the coupling mechanism of pore development and mineral composition as well as origins in organic-rich shales.

Key words: Middle-Upper Yangtze region, Lower Cambrian, Shale gas, Water uptake experiment
