Shale gas is a kind of unconventional gas. Shale gas reservoirs are typically continuous, having complex texture with low porosity and low permeability, so they needs advanced technology for production. Current situation of shale gas development in China and abroad is summarized. Through in-depth investigating and summing up shale gas exploration and production history and successful experience in North America, it is thought that key factors of shale gas effective production includes optimization of sweet areas and drilling and fracturing techniques. Comprehensive geological evaluation is the basis for shale gas development, and reservoir reconstruction technique is the core of producing reserves. The main geological parameters for selection shale gas enrichment areas and main aspects for drilling and well completion optimization are introduced. Together with actual comparison of the geological and engineering parameters in different shale gas wells, the ideas of successful shale gas development are proposed. Based on the study of reservoir description and evaluation, specific fracturing design and reasonable engineering parameters should be carried out in order to increase the ESRV(Effective Stimulated Reservoir Volume) and obtain high production.
