New Drilling Technology of Shale Gas and Tight Gas

Nowadays, foreign developers of shale gas, specially the United States, have the most sophisticated and mature development technology in the world, In the analysis of the development process, horizontal well and large-scale reservoir reconstruction is the golden key to develop unconventional oil and gas. This paper summarized on typical and latest technologies of foreign shale gas in recent years, such as drilling tools, drilling fluids, drill bits and multi-well pad drilling. According to the domestic technological condition, the main research directions of future drilling technology for shale gas in China has been identified. Such a series of matching technology will promote the arrival of the 2.0 era of shale-gas development in the world, and it also has important significance for speeding up the pace of Chinese shale gas development.
