吐哈盆地页岩气有利勘探方向

Favorable Targets for Shale Gas Exploration in Tuha Basin

分析了国外页岩气藏的关键地质参数,归纳总结了国内外页岩气有利探区的遴选原则,并根据吐哈盆地的地质条件,提出了页岩气探区的基本评价标准。综合评价、分析了吐哈盆地水西沟群和小泉沟群两套页岩的基本地质条件后指出,它们具备形成页岩气藏的基本地质条件,2套页岩的生气潜力巨大;台北凹陷东部、哈密三堡凹陷是页岩气勘探的有利区块。

The key parameters of the shale gas reservoirs abroad are analyzed,and the principles of strategic areas for exploring shale gas at home and abroad are reviewed.Based on the geological conditions in Tuha basin,the general evaluation standards of these areas,the basic geological conditions of forming shale gas reservoirs for two sets of shale strata of Shuixigou group and Xiaoquangou group in this basin are evaluated comhensively.It is suggested that the eastern Taibei sag and the Hamisanbao sag in Tuha basin are favorable targets for shale gas exploration.
