Core Viewpoint - China National Petroleum Corporation (CNPC) has achieved a significant milestone in the field of Carbon Capture, Utilization, and Storage (CCUS) technology by successfully operating its first domestically produced high-pressure injection compressor with a capacity of 100,000 cubic meters for over 10,000 hours, marking a breakthrough in the localization of CCUS equipment [1][2] Group 1: CCUS Project Development - The successful application of the high-pressure injection compressor is a key achievement for CNPC, overcoming the reliance on imported equipment and addressing the "bottleneck" issue in critical CCUS technology [1] - The core of CCUS involves injecting captured carbon dioxide underground for oil recovery and storage, with CNPC establishing China's first supercritical CO2 injection station in Jilin Oilfield in 2014 [1] - Historically, the injection station's core equipment, the high-pressure injection compressor, relied on imports, leading to high operational costs and delays due to long procurement cycles [1] Group 2: Technological Innovations - In response to challenges, CNPC initiated independent research and development, starting with the modification of a small valve component, which led to significant improvements in compressor performance and reduced energy consumption [1][2] - The CCUS technology team discovered and optimized the lubrication process of the compressor, extending the usage period of lubricating oil from 7 days to 9 days through adjustments in the oil drip rate [2] - In 2023, CNPC successfully completed industrial testing of the first domestically developed supercritical CO2 injection compressor unit, marking a significant step towards full localization of CCUS technology [2] Group 3: Future Prospects - Jilin Oilfield is currently conducting simultaneous field tests of various core equipment, including the domestic compressor and intelligent flow meters, with plans for large-scale production and deployment [2] - The successful development of the first full-chain CCUS engineering dedicated compressor in Asia and the first domestic CO2 water-gas co-injection device indicates a comprehensive shift towards domestic alternatives for previously imported products [2]
