Core Insights - China National Offshore Oil Corporation (CNOOC) has successfully achieved a significant milestone in carbon capture and storage (CCS) with its Enping 15-1 oilfield project, having stored over 100 million cubic meters of carbon dioxide, equivalent to the carbon offset of planting 2.2 million trees [3] Group 1: Project Overview - The Enping 15-1 oilfield is China's first offshore high carbon dioxide content oilfield, which, if developed conventionally, would lead to increased carbon emissions and corrosion of offshore facilities [3] - CNOOC has invested four years in research to implement the first offshore CCS project in China at this oilfield, achieving an annual carbon dioxide storage capacity exceeding 100,000 tons [3] Group 2: Technological Advancements - In May, the first offshore carbon capture, utilization, and storage (CCUS) project was launched at the Enping 15-1 platform, marking a comprehensive upgrade in offshore CCUS technology, equipment, and engineering [3] - The project introduces a new model of marine energy recycling, termed "carbon-driven oil, oil-solid carbon," which enhances oil production while simultaneously achieving carbon dioxide storage [3]

2023年6月，中国海油在恩平15-1油田投用了中国海上首个CCS(二氧化碳捕集、封存)示范工程，截至目 前已累计安全运行近13000小时，回注二氧化碳超18万吨。 此次启动的二氧化碳驱油项目，将进一步实现二氧化碳的有效利用，不仅实现增产，而且能降碳，推动 海上CCS向CCUS技术转变。 中国首口海上CCUS井开钻，预计十年注入二氧化 碳超百万吨 3月26日晚间，中国海油官微发布消息称，日前中国首口海上CCUS井(二氧化碳捕集、利用与封存)在位 于珠江口盆地的恩平15-1平台开钻。该项目预计10年累计规模化向海底地层注入二氧化碳超100万吨。 据中国海油介绍，恩平15-1平台是目前亚洲最大的海上原油生产平台，所在海域水深约90米。该平台所 开发的恩平15-1油田为高含二氧化碳油田，若按常规模式开发，二氧化碳将随原油一起被采出地面，不 仅对海上平台设施和海底管线造成腐蚀，还将增加二氧化碳排放量。实施CCUS项目，可实现油田增储 上产与绿色低碳的相互促进、协同发展。 恩平15-1油田CCUS项目的研究于2023年底启动。中国海油经过研究，选出距离恩平15-1平台2.4公里、 地下1200至1600米的4个"黄金层 ...
