Abstract:

Shale gas,as a clean energy of great prospects,has become the research hotspot in petroleum geology field,recently.
Shale gas exploration of Qiangtang Basin,where several high quality mud-shale source rocks developed,is still in initial stage.
Through the analysis of key geological parameters of domestic and international main shale gas basins in exploration and
development,we sum up the evaluation standard of favorable shale gas exploration targets. Based on the comprehensive
evaluation of the main mud-shale hydrocarbon source rock thickness,organic matter maturity,organic matter type,organic
carbon content of Qiangtang Basin,we discover that in Qiangtang Basin,two sets of favorable shale gas exploration layer
developed:mud-shale layer of the upper Triassic,mud-shale layer of lower Jurassic Quse Formation. And we select five
favorable shale gas areas:Zangxiahe favorable area,Woruoshan favorable area,Tumengela favorable area,Biluocuo favorable
area,Mugouriwang favorable area.

Key words: Qiangtang Basin, shale gas, evaluation standards, conditions of accumulation, favorable area
