Abstract:

Shale gas as an important unconventional resource,is essential for our energy security and supply,but the shale
reservoir is of low porosity and extra-low permeability characteristics,and hydraulic fracturing is needed to obtain the desired
economic output. We summarized the advanced technology used in American shale gas exploitation in the paper. Based on
the shale gas reservoir characteristics and technology development of China,we also discussed the directions of large-scale
development of shale gas in China. The results indicate that economical development of north American shale gas benefited
from the advanced reservoir evaluation,horizontal drilling and hydraulic fracturing. And we also further evaluated the latest
developments in north American shale gas,including reservoir evaluation,fracturing material and design optimization,production
evaluation. In addition,discussion of technology adaptability and basic principles of various technologies are presented.
In order to improve the development of shale gas in China,from exploration to development,we should learn from combining
advanced experience with our reservoir features to carry out science and technology research,such as whole optimization of
exploration and development,the volume fracturing mechanism and related technology,the evaluation of negative effects of
shale gas development.

Key words: shale gas, high efficiency exploitation, horizontal drilling, hydraulic fracturing, enlightenment
