摘要

China is experiencing rapid industrialization and economic growth.However, becoming a world-leading scientific and technological power takes a heavy toll in terms of energy consumption.Although China covers a vast territory, resources are not abundant.Therefore, establishing a reliable, stable, and strategic reserve is an urgent task to guarantee long-term supplies and lead the global development.By analyzing the current processes for the exploitation of fossil fuels in China and abroad, the following conclusions were drawn:①the exploration and development of fossil fuels in the so-called second deep space (5 000~10 000 m) will become strategic by the middle of this century and will supply a bulk of the disposable energy; ②in the process of minimizing pollution and costs through advanced technologies, the development of unconventional oil and gas resources, specifically shale oil and gas reservoirs, will be inevitable; ③the current balance of energy sources, dominated by coal, coalbed gas, oil, and power generation by underground combustion, is not expected to change and, the development of the coal chemical industry will remain strategic.Based on the above points, it is expected that China's energy supply in the mid-21st century (and possibly beyond) will come from a combination of conventional oil and gas from the second deep space, coalbed gas, and unconventional shale gas.
