Abstract: China is rich in shale oil and gas resources but faces a series of challenges in this area, such as technological gap, lack of the economic evaluation system, shortage of market mechanisms and some external interference. Therefore, development progress is unmatched with resource endowment. Led by the development conceptions of creation, synergy and deregulation and based on development of Zhaotong shallow-layer shale gas and Da’an area, western Chongqing deep-layer shale gas, Zhejiang Oilfield came up with the strategy focusing on improvement of EUR, improvement of performance and efficiency and reduction of investment cost, thus aiming at its internal revenue rate. The company made the efforts to study the path for realization of China’s shale oil and gas revolution. Zhaotong shallow-layer shale gas development was based on localized technological innovation, flexibility of pilot experiment, reform of the gas prizing mechanisms and synergy of industrial chain to bring about the transition from conventional mode to priority of economic performance. As for Da’an area, western Chongqing deep-layer shale gas development, EUR was raised by means of detailed technological research while synergy of full industrial chain and market-orient operation reduced the cost for higher efficiency with the drilling period and single-well drilling expense dramatically lowered. The platform cumulatively saved about 20 million yuan thanks to modernization of the liquid control and sand lifting technology. In the future time, Zhejiang Oilfield will further promote development of technological revolution on the basis of engineering innovation. The study indicates that localized technological innovation, synergy of full industrial chain, the “put economic performance first” development mode, application of market mechanisms and preferential policies are the critical path for China’s large-scale shale oil and gas development.
