Core Insights - The Shanshan-Lanzhou pipeline has transported over 200 million tons of crude oil as of November 21, supporting national energy supply diversification and economic development in the central and western regions [1][2]. Group 1: Pipeline Overview - The Shanshan-Lanzhou pipeline, a crucial part of the western oil and gas energy strategy, spans 1,541 kilometers from Shanshan County in Xinjiang to Lanzhou in Gansu, with a designed capacity of 20 million tons per year [2]. - Since its commissioning in 2007, the pipeline has operated safely for 18 years, increasing its oil transport capacity from an initial 1,000 cubic meters per hour to over 2,000 cubic meters per hour [2]. - The pipeline has evolved from transporting four types of crude oil sequentially to a more efficient mixed oil transport system, showcasing advancements in long-distance crude oil pipeline technology and management [2]. Group 2: Resource Connectivity - The Shanshan-Lanzhou pipeline connects resource bases in Xinjiang with markets in central and eastern China, facilitating the transport of crude oil from major oil fields and Central Asian resources to key locations such as Yumen, Lanzhou, and Chengdu [2]. - The resources transported via the Shanshan-Lanzhou pipeline are refined by petrochemical companies and further distributed through the national pipeline network to provinces including Shaanxi, Henan, Sichuan, Chongqing, Hubei, and Hunan, thereby extending the downstream industrial chain [5].
