页岩油的规模效益开发对我国的能源安全具有重要意义，但目前在资源品质、开发技术、配套设施、市场化程度等方面存在诸多挑战。为此，在分析低油价时期美国二叠盆地页岩油开发实现大幅降本增效成功经验的基础上，指出我国页岩油规模效益开发需要采用理念转变、技术创新、管理创新和市场运作的技术思路，并提出了页岩油甜点识别与评价新方法、差异化压裂优化设计和全生命周期开发优化等3项关键技术，对实现我国页岩油规模效益开发具有一定的推动作用。

The benefit of scaled development of shale oil is of great significance to national energy security in China. However, there are many challenges at present in terms of resource quality, development technology, supporting facilities, and the degree of commercialization and widespread adoption. This paper analyzes the successful experiences in the Permian Basin of the United States in significantly reducing costs and boosting efficiency in the shale oil development, despite a general environment oflow oil prices. By looking at this case study, we can see that the technical ideas of concept transformation, technical innovation, management innovation and market operation are necessary for China as well, if China is to to realize benefit development of shale oil and three key technologies. For example, new methods of shale oil sweet spot identification and evaluation, differential fracturing design optimization and full life cycle development optimization are applicable to China. They are advanced in this paper and will provide some help in achieving the goal of scaled benefit development of shale oil in China.
