【Abstract】 To address the problems of high energy consumption,high emissions,and insufficient multi-energy synergy in China’s shale oil and gas development process, this study focuses on optimizing energy use throughout the entire mining area development process. It systematically analyzes the energy consumption characteristics and energy-saving potential of the four major stages: drilling, fracturing, mechanical oil recovery, and station production, and proposes multi-dimensional efficient energy use paths. Specifically, in terms of energy structure optimization, the focus is on promoting the "electricity-for-oil" technological upgrading of drilling rigs and fracturing units to significantly increase the proportion of clean energy such as electricity and natural gas. In terms of power supply system construction, the main network structure will be further strengthened, and the redundancy of power supply capacity will be improved to ensure the continuous and stable power supply for critical production loads. In the demonstration of direct green electricity connection, a multi-energy complementary mode of "wind, solar, storage, and gas" will be integrated to supply green electricity to core energy-consuming scenarios through direct connection lines. In terms of energy conservation and efficiency improvement, it is ensured that transformers and motors of core energy-consuming equipment meet the energy efficiency level of Grade 2 or above, and technologies such as cascade utilization of waste heat in stations, wellhead vortex tube heat extraction, and optimization of energy flow in mining areas are promoted. The above research will promote China’s shale oil and gas mining areas towards in-depth optimization of energy use structure, large-scale penetration of renewable energy, and step-by-step improvement of energy efficiency throughout the entire process.更多还原
