Study on transportation management of oil pipeline
As a large oil importer, China imports half of the total oil consumed in China every year, and the main way to transport oil is pipeline transportation. Therefore, it is particularly important to strengthen the management of oil pipeline transportation industry. This paper briefly analyzes the development status, existing safety problems and protection measures of China’s oil pipeline transportation industry, and makes suggestions on how to improve the management system of oil pipeline transportation industry.
With the development of society, oil, as one of the lifeblood of China’s economy, has been widely used in all walks of life, and its demand is increasing day by day. However, due to the limitation of China’s mining technology and resource output, a large amount of oil needs to be imported from abroad, which also drives the development of oil transportation industry. Pipeline transportation is favored by people as a safe, environmental friendly and fast way of oil transportation; However, due to its huge investment and complex engineering, it has many management problems, prone to omissions, and even endanger the safety of people’s lives and property. These are the hidden dangers that need to be solved urgently in the oil pipeline transportation industry.
Brief introduction of oil pipeline
Oil pipeline refers to a pipeline system composed of oil pipes and other accessories and assembled with corresponding oil pumps and other machines according to a certain process flow, which is used to complete the loading, unloading, transportation and transportation of oil (including crude oil and product oil). Its materials are generally steel pipes (generally carbon steel pipes and oil resistant rubber pipes), Long distance connection of pipes shall be carried out by welding, flange and other connection methods. Oil pipeline transportation is the most common way of oil transportation in China.
Development status of China’s oil pipeline transportation industry
In today’s world, there are many ways of oil transportation. In addition to pipeline transportation, there are also road transportation and railway transportation. However, pipeline transportation is more convenient and fast without being limited by time, space, season and other factors. Therefore, pipeline transportation has become the most important way of oil transportation in China. However, due to the broad prospect of oil pipeline transportation industry, there are many operators, which leads to the extremely complex and imperfect management system of pipeline transportation, which is easy to lead to various safety accidents, such as explosion and fire caused by oil leakage; These adverse factors are the biggest obstacle to the development of China’s oil pipeline transportation industry.
However, even so, in the past decade, China has invested in the construction of many important oil transportation pipelines, such as Lanzheng Changcheng oil pipeline, Lancheng Chongqing oil product pipeline, gangzao oil product transmission pipeline, western pipeline crude oil pipeline and oil product pipeline, etc. These oil pipelines can be roughly divided into two types: crude oil transmission pipeline and product oil transmission pipeline. The following is a brief introduction to the construction status of these two transportation pipelines.
Crude oil pipeline
After continuous research and development in recent years, China’s crude oil pipeline transportation technology has made great progress in technology, and is narrowing the gap with foreign advanced technology. Nowadays, China has mastered advanced pipeline transportation technologies such as additive transportation, heating transportation, normal temperature transportation, intermittent transportation, closed transportation and sequential transportation, especially the heating transportation and additive transportation technology has reached the international level, and has made great achievements in anti-corrosion, thermal insulation and corrosion detection.
Product oil pipeline
With the increasing demand for product oil transportation, China’s product oil pipeline construction has also made some progress. It has successively developed hydraulic training calculation for product oil sequential transportation and batch tracking and operation management software to assist the pipeline transportation of product oil. However, the current overall level still lags behind the international level. At present, China mostly adopts closed sequential transportation process for product oil pipeline transportation, and some others adopt sequential transportation process of side connected oil tank, but the automation and scientific and technological level are low, which needs to be further developed and developed by relevant researchers and workers.
Safety problems in oil pipeline transportation
Quality problems of pipeline materials
The construction of oil pipeline engineering costs a lot of money and often requires tens of billions of investment. Therefore, many operators use unqualified pipeline materials in order to save money and strive for profits, resulting in serious oil leakage and excessive waste, which is more likely to cause severe explosion and fire, and bring irreparable disaster to the society.
Most oil pipelines are made of steel pipes, which are usually exposed in the air or deeply buried in the soil. After the service time reaches a certain degree, there will be corrosion, which has a great safety risk.
As China has a vast territory, it needs to transport oil for a long distance and build oil pipelines for a long time, so it needs to connect different pipelines through welding technology. Welding quality plays an important role in the construction of pipeline engineering. If the welding technology is not qualified, the connection at the interface is poor or the welding process is not meticulous enough, it is easy to cause accidents such as seismic cracking in the process of oil transportation, which has a great adverse impact on the safety of oil pipeline transportation. In China, there have been many safety accidents in the process of oil pipeline transportation caused by welding problems. We must pay attention to this problem to avoid the recurrence of accidents.
Protective measures for oil pipeline transportation
Ensure pipeline quality
During the construction of oil transportation pipeline project, we must carefully detect the quality and safety performance of the required materials, strictly control them, resolutely refuse to put unqualified products into the construction, do not use inferior materials in order to save costs, let alone steal work and materials, and always remember to be responsible for the safety of society and people’s lives and property.
Do a good job of protection
As the oil pipeline is easy to be corroded, it has increasingly affected the development of China’s oil pipeline transportation industry. Therefore, how to protect the transportation pipeline from corrosion is also the top priority. At present, the most important protective measure in this regard is to coat the pipeline with anti-corrosion paint, which can not only reduce the corrosion degree of the transportation pipeline, but also greatly prolong the service life of the pipeline and save part of the cost for the pipeline construction project. It is an extremely effective protective measure for oil transportation pipeline.
Guarantee welding technology
The welding technology of oil transportation pipeline must pass the test. The technicians who carry out welding work must receive professional welding technology skills training, meet the requirements of national professional standards, have a certain sense of professional ethics and work responsibility, be conscientious and careful in the welding process, and strictly control the welding quality of oil transportation pipeline, Avoid quality problems caused by individual or group negligence and non-standard technical level; In addition, it is necessary to clearly divide the responsibility attribution, so that someone can bear and dare to bear the problems, and can make up for and solve them in time.
Improve the management system of oil pipeline transportation industry
As the saying goes, “no rules, no radius”. Any enterprise or project needs a perfect and complete system to restrict relevant workers, so as to achieve the purpose of supervision and supervision, and finally realize the high efficiency and high completion of the work. Similarly, for the oil pipeline transportation industry, in order to ensure the safety and efficiency of the oil pipeline transportation process, it is necessary to set up a relatively perfect and complete management system, divide in detail the important details, detailed responsibilities and obligations in the pipeline construction project and even the oil transportation process, and enhance the professional level and sense of professional responsibility of employees, Make everyone clearly realize the importance of oil pipeline transportation safety. Enterprises and individuals should be careless and careless. Only in this way can we really ensure the safety of oil pipeline transportation.
Taking Lanzheng Changcheng oil pipeline as an example, a brief analysis is made
Lanzheng Changcheng product oil pipeline is the longest product oil pipeline in China at present. It starts from Lanzhou City, Gansu Province, passes through five provinces and 67 cities and counties such as Gansu, Shaanxi, Henan, Hubei and Hunan, and ends in Changsha City, Hunan Province. The whole line has a total length of 3214km. It adopts 3PE anti-corruption scheme. It was started on August 18, 2007 and mechanically completed on December 31, 2008 after more than a year, It is a major construction project of CNPC. During its construction, it has adopted the construction methods of inclined shaft crossing, pipe well dewatering crossing and directional drilling crossing, successfully crossed more than 70 large and small rivers, 74 railways, 234 high-grade highways and 15 tunnels, and overcome many complex terrain such as water network swamp, loess hilly area, Loess Plateau and Liupan Mountain, It is an important milestone project in the construction of China’s refined oil pipeline transportation. It reflects the preliminary results of the “west to East oil transmission” strategic project of the State Council and the strategic deployment of the western development. At the same time, it is also an important factor in building a harmonious society. It can be described as far-reaching and of great significance.
As the most common and practical oil transportation mode in China, oil pipeline transportation is of great significance to China’s economic development and scientific and technological development. More in-depth and pioneering research on the management of oil pipeline transportation is the most basic requirement of China’s modernization, an important factor for building a harmonious society, and an important issue valued by the party and state leaders. It helps to reduce the cost of China’s oil transportation, improve the efficiency of China’s oil transportation, and solve the shortage of China’s oil resources Limited development technology and other issues, so that China can further realize internationalization.
