Abstract:

The occurrence and productivity potential of shallow shale gas in the Taiyang anticline area of Zhaotong National Shale Gas Demonstration Zone are controlled by five major geological factors including the thickness, physical properties, sealing properties of roof and floor, and compressibility of organic-rich shale reservoirs. The gas reservoirs are characterized by high adsorbed gas content, weak overpressure, relatively low initial production, stable production of gas well, and low decline rate. Through innovation and integration, the authors have developed the evaluation technology for selecting the sweet spots of shallow shale gas, productivity target-oriented efficient well spacing technology, geo-steering technology of near bits made in China, safe, efficient and fast drilling technology, as well as the key efficient exploration and development technologies such as volume fracturing, fine pressure control, and discharge and mining technology of shallow shale gas, established a demonstration base of shallow shale gas development in the Taiyang anticline area, promoted the exploration and development of shallow shale gas in the Zhaotong National Shale Gas Demonstration Zone, and led the exploration and development of shallow shale gas in marine mountainous regions in complex structural areas of south China outside the Sichuan Basin.

Key words: efficient development, key technologies, geological characteristics, shallow shale gas, Wufeng-Longmaxi formations, Taiyang anticline area, Zhaotong National Shale Gas Demonstration Zone
