大庆油田：绿色蝶变的高质量发展之路

Core Viewpoint - Daqing Oilfield is actively implementing green development practices, aligning with the "Two Mountains" theory and the concept of "green water and green mountains are as valuable as mountains of gold and silver," to achieve high-quality development through ecological protection and resource optimization [1][4][11]. Green Development - Daqing Oilfield has transformed polluted sites into green landscapes, utilizing waste treatment technologies to convert waste into eco-friendly materials, thereby enhancing its ecological footprint [3][4]. - The oilfield is committed to building a "waste-free green oilfield" by improving pollution prevention systems and reducing total pollutant emissions [3][4]. Carbon Neutrality Initiatives - The oilfield has achieved a 100% water reuse rate through a "producing—treating—reinjecting" cycle system and has improved water injection quality to over 90% with its self-developed "injection" system [4][6]. - Daqing Oilfield's CO2 enhanced oil recovery technology represents a significant advancement in sustainable oil extraction, addressing challenges in low-permeability oil fields while contributing to industrial carbon cycling [4][6]. Green Energy Transition - The oilfield is transitioning from oil extraction to green energy production, implementing a multi-energy complementary low-carbon development model, including low-carbon oil and gas production, clean energy supply, hydrogen industry, and CCUS [6][7]. - The Lama Dian Oilfield low-carbon demonstration area is the largest of its kind in China, featuring a combined wind-solar-thermal-hydrogen energy system with a total installed capacity of 150,000 kilowatts and generating over 400 million kilowatt-hours of electricity [6][7]. Biodiversity and Ecological Protection - Daqing Oilfield has established biodiversity protection areas, transforming previously degraded lands into thriving ecosystems, with significant improvements in plant and bird species diversity [9][10]. - The oilfield's annual tree planting efforts exceed 500,000 trees, contributing to carbon neutrality and enhancing the local environment [10][11].
