This western energy artery has delivered a total of 120 million tons of refined oil to the Sichuan-Chongqing region in the past 20 years

As a key project for the large-scale development of the western region, the Lancheng-Chongqing refined oil pipeline has ushered in 20 years of
safe operation.
In the past 20 years, the pipeline has delivered a total of 120 million tons of refined oil to the Sichuan-Chongqing region, effectively balancing the energy structure of the western region and becoming the main energy artery
in the western region.
In the past earthquakes, floods, landslides and other large-scale natural disasters to play a meritorious role in energy supply, known as the "energy lifeline"
that can not be destroyed.

On December 18, 1998, a cannon in the Guanshan Tunnel kicked off the construction of the Lancheng-Chongqing refined oil pipeline
.
On September 29, 2002, the first station in Lanzhou began to deliver diesel, and on October 18, the diesel arrived at the last station in Chongqing, and it was fully completed
.
In 2012 and 2016, after the increase and transformation of Jiangyou Oil Transmission Station and Ziyang Oil Transmission Station, the pipeline oil transmission capacity jumped from 5 million tons to 7.
5 million tons, and at the highest time, it once undertook more than 80% of the refined oil supply in Sichuan and Chongqing, providing a stable and strong guarantee
for the transportation of refined oil products in Sichuan and Chongqing.
In 2014, Lanchengyu Pengzhou injected into the branch line into production, so that the refined oil produced by Sichuan Petrochemical can directly enter the Lanchengyu refined oil pipeline through the pipeline, and the pipeline is transported to the downstream markets of southern Sichuan and Chongqing, so as to ensure the supply of two resources of Lanzhou Petrochemical and Sichuan Petrochemical, and further enhance the
service market capacity.

It is understood that the Lanchengyu refined oil pipeline is China's first large-caliber, high-drop, high-automation refined oil pipeline, the maximum height difference of 2270 meters, management and operation is extremely
difficult.
Starting from Lanzhou City, Gansu Province, across Gansu, Shaanxi, Sichuan and Chongqing, all the way to the southwest, it continuously delivers industrial and people's livelihood energy "blood" for the Sichuan-Chongqing region, which is the energy artery of the economic development of the southwest and "refuels" the regional economic take-off
.

"As the specific operation of the pipeline after entering the river, in view of the flood for many years, combined with the hydrological and geological conditions, overcome many difficulties, and change the original 14 large-scale excavation methods to cross the river pipeline to directional drilling to cross the river, completely eliminate the harm of flood flooding to the pipeline, and realize the intrinsic safety
of the pipeline.
" 。 The relevant person in charge of the Lanchengyu Branch of the National Pipeline Network Southwest Pipeline Company said that after the test of landslides, floods, earthquakes and other major dangers covering all types of pipeline industries, the branch has strengthened the leadership of party building, and the role of the party branch as a fighting fortress and the vanguard and exemplary role of party members have been fully utilized, adhering to their posts and charging forward to ensure that the pipeline always runs
safely and smoothly.
Pipeline protection personnel use footsteps to measure and patrol every inch of the pipeline, timely discover and dispose of hidden dangers, work together from top to bottom, overcome difficulties together, and successfully deal with various emergencies
