Abstract: Because of the strong heterogeneity of shale gas reservoir,the key to economic and effective shale gas development is to achieve the best match between engineering parameters and reservoir conditions.In this paper,the analysis of problems during shale gas development in China has been obtained;the analysis methods and key technologies of shale gas reservoir characteristics have been elaborated.From the view of integration of geology and engineering,the technical idea and methods of engineering closely related to shale reservoir characteristics have been discussed systematically,and the shale gas geology and engineering integration technology system has been established.
