Strategies for scale benefit development of deep shale gas in China

China is abundant in deep shale gas resources, which is a real field for the production increase of natural gas in the future, so their scale benefit development is of great strategic significance to ensure the national energy security. After reviewing the progresses and achievements in the scale benefit development of deep shale gas resources, this paper analyzes and summarizes four great opportunities and five major challenges. The four great opportunities are as follows. First, in China, the natural gas market has huge space and the development prospect of shale gas is promising. Second, the state and local governments pay attention to and support shale gas exploration and development. Third, there is a resource base for deep shale gas production increase and stabilization. And fourth, technological progress will accelerate the scale benefit development of deep gas. The five major challenges are follows. First, the exploration and development of deep shale gas is more difficult than that of shallow shale gas. Second, the capacity of exploration and development technologies and equipment is not sufficient. Third, the exploration and development cost is higher and the cost reduction and efficiency improvement is of high difficulty. Fourth, the production, operation and management system needs optimizing further. And fifth, the coordination between enterprises and local governments gets more and more difficult. In conclusion, the basic principles shall be followed strictly, such as top-level design, co-construction and win-win, market operation, and inheritance and innovation. In addition, it is recommended to optimize and improve the following measures to promote the scale benefit development of deep shale gas in China by referring to domestic and foreign experiences in the scale benefit development of typical shale gas blocks. First, improve the production organization mode and maximize synergistic effect. Second, strengthen technological researches and promote science and technology leading. Third, establish market-oriented engineering and technology service mechanism and vitalize shale gas development. Fourth, deepen the cooperation between enterprises and local governments and promote co-construction and win-win. Fifth, speed up the cultivation of natural gas utilization industrial clusters and promote the in-situ utilization of shale gas. And sixth, actively strive for industrial support from governments and optimize the policy environment.
