Abstract: Mountain shallow shale gas in Taiyang Area of Zhaotong National Demonstration Zone, as the first large-scale integrated shallow shale gas field developed for industry in China, has entered the stage of large-scale commercial development at present, which proves that shallow shale gas in the complex structural area of the strong reconstruction outside the Sichuan Basin has a good exploration and development prospect, and has important enlightenment significance for the development of shale gas in China. Based on the efficient development innovation practice of geology and engineering integration in shallow shale gas field, this paper systematically summarizes the core connotation of geology and engineering integration, and forms the key technology working method of geology and engineering integration suitable for mountain shallow shale gas exploration and development. Exploration and development practice experience shows that based on the comprehensive evaluation of geology and engineering integration concept, through the integrated evaluating platform, the integration of synergy to the whole life cycle of shale gas well quality of "4Q":reservoir quality (RQ), drilling quality (DQ), completion quality (CQ), production quality (PQ) are assessed and production system is optimized, to achieve well quality, engineering effect, single well production.

Key words: shallow shale gas, Taiyang mountain shallow shale gas field, geology and engineering integration, efficient development innovation practice, quality of “4Q”, the whole life cycle
