记者从中国石油天然气股份有限公司吉林油田分公司获悉：截至12月3日，中国石油在吉林油田二氧化 碳捕集、利用与封存(CCUS)项目中应用的首台国产10万立方米高压注入压缩机，已安全稳定运行超过1 万小时。 将捕获的二氧化碳注入地下驱油和封存，是CCUS技术运用的核心。2014年，中国石油在吉林油田建成 国内首个二氧化碳超临界注入站——黑46循环注入站，其核心设备高压注入压缩机堪称注入站的"心 脏"。然而，这颗"心脏"长期依赖进口，当时每年进口阀片材料费高达80万元，且采购周期长，关键部 件损坏后要等待数月，严重影响试验的连续性和经济效益，成为CCUS技术大规模工业化推广的潜在问 题。 面对困境，中国石油选择自主攻关，从一个小小的阀片开始做起。阀片是压缩机中高速往复运动、易损 耗的关键部件，其作用类似于医用注射器推管，用来吸入和密闭二氧化碳气体。2020年，吉林油田 CCUS技术攻关团队向进口阀片垄断发起挑战。经过几十次试验，一年后阀片改造成功，更换周期从1 个月延长至3个月以上，压缩机处理能力提升至额定排量的115%，年节约电费超100万元。 吉林油田CCUS技术攻关团队还在压缩机运行中通过大数据分析和对数万组 ...
