Abstract： Earth Sciences is a multi-disciplinary science, which takes the interaction of Earth’s various spheres and their resources and environmental effects as the research object. As a comprehensive and systematic science that not only expands the frontier of human knowledge but also serves the social and economic development of human beings, Earth Sciences not only studies the past and reveals the evolution history of the Earth, but also faces the future and provides solutions for the sustainable development of human beings. Based on the analysis of the international development trends of Earth Sciences and the summary of the development status and sci-tech funding of Earth Sciences in China, this study proposed that the future development direction and research plan of Earth Sciences in China should be arranged from the perspective of system science and national needs; and from the perspective of the Earth system as a whole, while attention should be paid to the interaction of various spheres and elements in the Earth system and their influence on the social and economic development of human beings. It is extremely necessary to guide the development directions of Earth Sciences research with “Four Orientations”, carry out major scientific research in an organized way, and improve the mechanisms of sci-tech funding and evaluation, so that the research achievements can better serve the national major strategic needs.

Abstract： Shale oil boom in the United States has catapulted it from an importer of crude oil to a net exporter. Field applications show that both the shift in exploration paradigm from finding traps to targeting resource-rich petroleum source kitchens (i.e., “sweet spots”) and the technological innovation represented by horizontal well multi-stage fracturing are among the key factors for the large-scale development of shale oil in the United States. Compared with marine shale oils in North America, China’s lacustrine shale oil resources have great potential, but the endowment conditions are not optimal. Early exploration and development experience shows that the adaptive technology for lacustrine shale oil needs to be solved urgently. Under the continuous efforts of the petroleum industry and relevant scientific research institutions, China has achieved partial breakthroughs in the shale oil development and utilization, and more efforts are now on the way to make greater strike. Once the production potential and commercial productivity are realized, shale oil revolution will spread in China and change the domestic energy landscape. Several policy suggestions are made on the shale oil development and utilization in China, based on the global trend analysis and a comparative study of the geological and engineering characteristics of shale oils in China and the United States.

Abstract： The development of energy science and technology has profound impacts on the future energy pattern, and the outlook of energy development is of great significance to national policy-making and corporate strategic planning. Based on the analysis of the current situation and development trend of energy sector, this study summarizes the five characteristics of energy transformation: diversification, decarbonization, decentralization, digitalization, and globalization, and points out three new features in respect of the trade war between China and US, low oil price, and application of artificial intelligence technology that emerged since 2016. A few thoughts concerning low-cost technology, information technology, and subversive technology are presented for analyzing the development trend of science and technology in energy sector, actively responding to energy transformation and formulating development strategy of energy science and technology.
