PETROCHINA(SH:601857) Xin Hua Wang·2025-10-11 11:29Core Viewpoint - The article discusses the green transformation of the Jidong Oilfield, focusing on carbon recycling and energy efficiency improvements in oil production processes [1][2][4]. Group 1: Carbon Recycling and Utilization - The Jidong Oilfield is implementing a project to inject 20,000 cubic meters of carbon dioxide into oil layers to enhance oil recovery, with a maximum injection capacity of 60,000 cubic meters per day expected after full production [1][2]. - The project aims to recycle over 30,000 tons of carbon dioxide annually, significantly reducing external procurement costs and ensuring stable production [2]. Group 2: Energy Efficiency and Cost Reduction - The Jidong Oilfield has optimized its operational systems, promoted energy-saving equipment, and implemented meticulous management, leading to an 18.5% improvement in energy efficiency across production systems [4]. - The oilfield has closed down 7 oil transfer stations, 185 metering rooms, and 7 water injection stations, reducing the total length of various pipelines by 323 kilometers, resulting in a 44.9% decrease in energy consumption compared to historical highs [4]. Group 3: Clean Energy Integration - The Jidong Oilfield is accelerating the replacement of traditional energy sources with clean energy, including solar thermal and waste heat utilization, to achieve a greener production process [4][6]. - The oilfield has installed 1,495 solar panels, generating over 920,000 kilowatt-hours annually, and has developed the largest water surface photovoltaic project under PetroChina, saving 28,200 tons of coal per year [6]. Group 4: Future Goals and Certifications - The Jidong Oilfield's land operation area became the first oil extraction unit in PetroChina to receive "carbon neutrality" certification, with plans to expand the use of renewable energy and implement carbon storage and carbon-driven oil projects [6].
