（来源：经济日报） 记者从国家管网集团西部管道有限责任公司获悉："十四五"期间，该公司锚定"全国一张网"目标，推进一批重大管道工程建设，累计完成重大项目投资 155亿元，建成和在建管道里程1019.2公里。 目前，自建项目准东煤制天然气管道支线工程正加速推进，该工程总长114.118公里，设计输量60亿立方米/年，已完成110公里焊接，较原计划提前60 天。"投产后，准东的煤制气将通过我们的管道直达长三角，为东部地区清洁能源供应再添新保障。"项目负责人说。与此同时，塔城——石河子甲醇管道 前期工作也有序开展，将为新疆煤化工产业打通新能源"出疆通道"，助力地方产业升级与经济发展。 2025年8月，西气东输果子沟战略安全管道工程1号山岭隧道成功贯通，创造了我国油气管道隧道建设技术的新高度。这座全长近6公里的隧道，是国内油 气管道领域单次掘进长度最长、海拔最高的山岭隧道项目，施工难度极大。施工团队秉持"敢为人先、勇攀高峰"的精神，成功啃下这块"硬骨头"，为"全 国一张网"建设打通关键节点。 图为西气东输二三线果子沟管道工程"平安号"航拍俯瞰照片。刘复合摄 转自：经济日报 图为阿拉山口输油站员工进行巡检。潘蕾伊摄 重 ...

本报讯 市发展改革委近日开展岁末年初油气长输管道安全生产检查，全力确保油气长输管道安全稳定 运行。 检查组一行实地走访浙江省天然气管网有限公司湖州作业区场站、省天然气管网施家桥高后果区、省天 然气杭湖线迁改项目现场施工区域等，详细了解安全生产措施落实情况。检查组要求，全市油气长输管 道各相关企业须高度重视岁末年初安全生产，严格落实管道保护主体责任，持续加强沿线巡护，做实做 细日常管理工作；要深入开展油气管道隐患大排查，重点加强对第三方施工点位巡查管控；同时应强化 应急值守，完善应急预案，定期组织演练，确保人员、装备、物资到位。 市发展改革委表示，此次检查进一步督促企业压实安全责任，提升油气管道安全保障能力，为全市岁末 年初安全生产形势平稳有序提供有力支撑。 （来源：湖州日报） 转自：湖州日报 记者 张翔 ...

数据显示，该管道投产以来，输油效率实现了倍增，从初期的每小时1000立方米提升至2000立方米以上。但更为关键的突破在于工艺的精细化与低碳化。作 为国内首条实现多品种原油同管道密闭顺序输送的大口径管道，其技术难度堪比在高速公路上指挥不同速度、不同载重的车队保持间距高速飞驰。这种"多 品种掺混顺序外输"技术，极大地提升了管网对不同油品市场的适配能力。 更值得一提的是其在节能减排上的"绣花功夫"。2015年以来，运营方利用首站28座储罐的地势高差，通过深入挖掘转油历史数据，实施了"以压代转"工艺优 化，每年直接节约电能达400万千瓦时。这种在存量资产上"抠"出来的能效，不仅实现了安全与经济效益的统一，更为传统能源基础设施的低碳化改造提供 了可复制的样本。它证明了，即便是传统的化石能源输送链条，也完全具备嵌入绿色低碳循环体系的潜力。 11月21日来自国家管网的一则数据却引发了能源观察界的深层思考：截至当日，中国最长的原油管道——西部原油管道（以下简称"西部管道"）已安全运行 18年，累计输送原油突破2亿吨大关。这条横贯西部的黑色动脉，不仅承载着从千米地层下开采的工业血液，更折射出中国在构建新型能源体系过程中，对 存 ...
