Three Advantages Of Oil And Gas Pipeline Transportation

(1) Low transportation costs. Railway, road and water transport oil and gas carriers are tankers and tankers. Some of the energy is consumed in the movement of the carrier, especially the empty vehicles and empty ships are required to return and cannot be transported continuously. The carrier of the seamless steel pipe is the pipe itself, and the oil and gas pump directly drives the oil and gas to flow around the clock. 

Only the large oil tankers sailing in the ocean have lower oil transportation costs than pipelines, but they are subject to geographical restrictions. In the 1990s, the cost of oil transportation for trains and automobiles in China was about 1.5 times and 20 times that of casing pipe transportation, and about 4 times and 8 times abroad.

(2) Small land occupation, small investment and fast construction. Railways and highways need to occupy about 20,000 square meters of land per kilometer for a long time, while the pipeline temporarily covers an area of 10,000 square meters per kilometer, and more than 95% of the land will be restored to its original state after completion. 

China's pipeline construction investment and construction cycle are only about half of the railway. The crude oil pipeline from Daqing to Qinhuangdao is 1,152 kilometers long and has a diameter of 720 millimeters. It takes only about two years to complete the production. If you build a dedicated railway of the same length, it usually takes 3 to 5 years.

(3) Convenient operation, large oil transportation, easy to realize management automation. Railway tank trucks usually transport about 2,000 tons of oil at a time. If an oil field produces 20 million tons of crude oil per year (the annual output of Daqing Oilfield is about 50 million tons), it will need to pump 10,000 oil tankers full of crude oil from the oil field every year, and return to the same number of empty vehicles. 

It is simple to know that it is equivalent to 55 train tankers entering and leaving the oil field every day. The pressure on rail transport is very large, and it is even overwhelming. However, as long as a pipe with a diameter of 720 mm is built, it is easy to transport 20 million tons of crude oil every year. At present, advanced oil and gas pipelines at home and abroad have realized the unmanned station and warehouse and automatic management of the entire line.

In addition, long-distance pipelines are generally buried in the ground, and fluid cargo is enclosed in the pipeline and isolated from the outside. Therefore, on the one hand, pipeline transportation has little environmental pollution, on the other hand, it is safe and reliable, and is not susceptible to changes in ground transportation, climate and other natural conditions. Interference and vandalism.
