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 ...

Core Insights - The West Oil Pipeline has surpassed a cumulative oil transportation volume of 200 million tons, reinforcing national energy security [1][5] Group 1: Pipeline Overview - The West Oil Pipeline stretches 1,541 kilometers from Shanshan, Xinjiang, to Lanzhou, Gansu, with a designed annual transportation capacity of 20 million tons [1] - It connects with the China-Kazakhstan oil pipeline and the Northern Xinjiang pipeline network, facilitating the transport of crude oil from the Tuhai, Xinjiang, and Tarim oil fields, as well as resources from Central Asia [1] - The pipeline has transported nearly 13 million tons of crude oil this year alone, with a cumulative transportation volume exceeding 68 million tons during the 14th Five-Year Plan period [1][3] Group 2: Technological Innovations - The National Pipeline Group has intensified technological innovation, enhancing the intelligent operation and maintenance system, and exploring "unmanned" repair operations [3] - The cleaning cycle for storage tanks at the first station of the Shanshan-Lanzhou line has been reduced from 80 days to 45 days, with an average annual fault-free operation time of over 40,000 hours for oil pumps [3] - The pipeline has transitioned from seasonal heating to year-round, closed transportation, becoming the first large-diameter long-distance crude oil pipeline in China to achieve closed sequential transportation of multiple types of crude oil [3] Group 3: Performance Metrics - Over 18 years of operation, the oil transportation volume has increased from an initial rate of 1,000 cubic meters per hour to over 2,000 cubic meters per hour, with annual transportation volume rising from 3.69 million tons to 14.45 million tons, marking a 391% increase [5]
