Western Crude Oil Pipeline is an oil pipeline in China.[1]


The pipeline has two segments, originating in Ürümqi, Xinjiang and terminating in Lanzhou, Gansu, China.

The pipeline delivers crude oil produced from Tarim Oil Field, Xinjiang and Tuha Oilfields, as well as those imported from Kazakhstan through Alashankou-Dushanzi Crude Pipeline, to the Lanzhou Refinery and Yumen Refining And Petrochemical Plant.[1][3] Construction began in March 2005, and it commenced operations on 30 June 2007.[4]

The Western Crude Oil Pipeline is China's longest pipeline of its kind, providing the longest transmission distance, the highest designed pressure, and the largest designed delivery capacity at the time of its commissioning in 2007.[3][4] It is constrained both by its oil sources and the downstream storage capacity, however, causing the pipeline to be operated at low flow rates in 2007-2008, with a high risk of pipeline coagulation and other transportation difficulties in winter.[3] At the end of 2008, the pipeline operators adopted blending (dilution of heavy crude oil to reduce viscosity) to improve oil transportation in the pipeline and reduce storage burden of the downstream refineries.[3]
