从“非常规”油藏榨出“科技油”——新疆油田打造吉木萨尔国家级陆相页岩油示范区纪实

Core Viewpoint - The Xinjiang oil field has established the first national-level continental shale oil demonstration area in China, focusing on both technical and economic feasibility for shale oil extraction [2][4]. Group 1: Technical Challenges and Solutions - The extraction of continental shale oil presents significant challenges, including deep burial, thin oil layers, and the need for precise drilling and high-pressure fracturing [2]. - Over the past decade, Xinjiang oil field has made breakthroughs in shale oil extraction, addressing three core challenges: identifying sweet spots, reservoir modification, and efficient development [3]. - The company has developed a set of advanced technologies, including a tracking technology for drilling and a combination fracturing technique that enhances flow efficiency [3]. Group 2: Economic Viability and Management - The Xinjiang oil field has implemented a "one full six optimization" production organization model to ensure economic viability in shale oil extraction, focusing on full lifecycle management and market-oriented operations [4]. - The introduction of market mechanisms has led to a 40% reduction in single well investment costs through project-based management [5]. - The demonstration area has improved drilling and fracturing efficiency, achieving a 58% completion rate for drilling in the past five years [6]. Group 3: Environmental Considerations - The company has adopted CO2-driven oil extraction methods and waste recycling initiatives to enhance ecological benefits in shale oil production [6]. - The implementation of platform-based development has reduced land usage by 50%, allowing multiple wells to be deployed from a single platform [6].
