Abstract: This paper presents the current development state of shale oil and gas in home and abroad and systematically reviews the new technologies, equipment, materials, and software in the fields of shale oil and gas drilling, completion, and fracturing engineering, which are developed by China National Petroleum Corporation(CNPC) based on adhering to a problem-oriented approach tailored to the geological characteristics of China’s continental shale oil and gas. Through comparing these technologies with the overall shale oil and gas engineering technologies in North American, the paper summarizes the issues and challenges faced by shale oil and gas development in CNPC, and then proposes development recommendations for a "Chinese version" of shale oil and gas engineering technology. These recommendations focus on continuously advancing the research and application of key technologies and equipment, accelerating the research and development of new-generation directional drilling tools, carrying out ahead of time the research and development of in-situ conversion technologies for medium- to low-maturity shale oil, and vigorously promoting digital transformation and intelligent development. The goal is to enhance the support provided by engineering technology for shale oil and gas resource development and strengthen its role in ensuring national energy security.
