"Although the accidents are handled more timely and effectively, the issue of the incident should be highly regarded by relevant parties. Otherwise, even more serious incidents of similar nature may still occur in the future," said Liu Tiemin, dean of the China Academy of Production Safety, and other experts. The “12·30†incident cannot be treated as a single case. It is from this incident that the deep-seated problems in China’s oil and gas pipeline safety work should be discovered and corrected.
Liu Tiemin said that from the analysis of the causes of many oil and gas pipeline accidents in the country in recent years, the proportion of third-party damage has continued to increase. Large-scale project construction and the illegal drilling and stealing of gas along pipelines have all triggered oil and gas pipeline accidents. . He believes that this requires that all levels of government must strengthen project planning and supervision, increase the publicity and law enforcement of the people's legal system, and work together with oil and gas pipeline operators to establish and improve the mechanisms and systems for protecting the safety of oil and gas pipelines.
According to reports, compared with developed countries, China's oil and gas pipeline safety still lacks fundamental legal and institutional guarantees. Although the "Oil and Gas Pipeline Protection Law (draft)" has been submitted to the Standing Committee of the National People's Congress for consideration, it has not yet been formally introduced. In addition, some local governments have not cracked down on the illegal elements of stealing oil and gas and damaging oil and gas transmission facilities, eventually leading to a rising trend of third-party destruction of oil and gas pipelines.
Professor He Guangxuan of Xi'an Petroleum University agreed with Liu Tiemin. He said: “To carry out extensive propaganda and education for the public and constantly improve the awareness of the people and the legal system is the key to ensuring the safety of oil and gas pipelines.â€
He Guangxuan told reporters that in recent years, the “contribution rate†of third-party damage to China’s oil and gas pipeline accidents has reached 40%, followed by corrosion, pipe quality, construction quality, and sudden natural disasters. According to He Guanglu, after 10 years of rapid development, the total mileage of China's oil and gas pipelines has now exceeded 50,000 kilometers, and in 2015 it will reach 100,000 kilometers, forming a major underground artery connecting east and west, across the north and south, and throughout the country. Although pipeline transportation has the advantages of less land occupation, less loss, low cost, large volume, and convenience, it also has long pipelines, many cross-regions, geological conditions along the way and the complex and varied natural environment, as well as quality, construction quality and monitoring of pipe materials. The level of safety and security requirements are high.
Compared to before the 1990s, China has already possessed world-class oil and gas steel pipe manufacturing enterprises such as Baoji Petroleum Pipe Co., Ltd., and the oil and gas pipeline transmission projects have all been constructed by large domestic companies such as PetroChina and Sinopec, and they have implemented Strict project quality is responsible for the system. Especially in the last eight years, the domestic pipeline and pipeline projects have all installed advanced automated monitoring systems. Both the enterprises and the government have formulated relatively sound and complete emergency rescue systems and plans. Therefore, at present, China's pipeline transportation and pipeline safety protection capabilities have risen to a relatively high level. However, compared with developed countries, the safety of oil and gas pipelines in China still has a certain gap. The average accident rate of oil and gas pipelines is 3 times per 1,000 km·year, which is much higher than the 0.5 times in the United States/1000 km·year and 0.25 in Europe. Times/1000 km·year.
Analyze the reasons for the high rate of accidents in domestic pipelines. He Guangxuan believes that the old pipeline has intrinsic safety problems because of the material, pipeline processing, welding, corrosion protection, construction quality, and monitoring level at that time; second, in recent years, China The construction speed and scale of pipelines are fast, but the construction of laws and regulations and supporting facilities for pipeline safety are lagging behind. The third and most important point is that we have failed to keep up with the people’s publicity and education work, and the people’s sense of legal protection for oil and gas pipelines is weak. Or do not understand the law at all.
For example, he said that all the people in the country now know that it is illegal to excavate and destroy highways and railways at will. However, a considerable number of people do not believe that the destruction of oil and gas pipelines must bear legal responsibility, and over 40% of the people do not know that the "Oil and Gas Pipeline Protection Ordinance" has been implemented. In some rural areas, they invade the pipeline at will, illegally construct buildings on the pipelines, construct extruded pipelines, and dig sand and earth outside the pipelines, resulting in the occurrence of bare and suspended pipelines crossing rivers.
The experts therefore appealed that, first of all, the legislature should formulate and promulgate the "Oil and Gas Pipeline Protection Law" as soon as possible, and local governments should formulate local laws and regulations for the protection of oil and gas pipelines, and widely publicize it so that the general public can understand the law. Secondly, it is imperative that those unscrupulous acts and persons responsible for destroying or jeopardizing the safety of pipelines be openly dealt with, and let the masses bear in mind that the destruction of the pipeline must be punished severely by law. Finally, we must clarify the duties and authorities of the pipeline operators, local governments, and social stakeholders. Oil and gas pipeline transportation often spans different provinces and regions, and its planning, environmental assessment, safety assessment, construction, and joint processing across provinces and regions after an accident all require a special agency to coordinate and coordinate.
Third Party Destruction Repeatedly Needs Legislative Remediation
On January 10, the reporter learned from the Environmental Protection Department of Shaanxi Province and the Environmental Protection Department of Henan Province that, after concerted efforts by various parties, the China National Petroleum Corporation (Land)-Zheng (State)-Changsha (Sand) finished products occurred on December 30 last year. A decisive victory has been achieved in the disposal of diesel leaks from oil pipelines on the southern branch of the oil pipeline. From 15:00 on January 5th, the concentration of oil contaminants in the Weihe River returned to normal levels before the accident. From 12:00 on January 6th, the concentration of oil in the water of the Sanmenxia Reservoir reached Class IV standard for surface water, and the drainage quality under the reservoir Continuously maintained in Class III standard of surface water, the water quality of the Yellow River returned to normal. At present, the parties concerned are properly handling the oil adsorbent and the contaminated soil to ensure that it does not cause secondary pollution.
