The hottest oil and gas pipeline Guardian pipeline

Oil and gas pipeline "Guardian"! The application of unmanned aerial vehicles for pipeline inspection has gradually become the norm

] in the face of thousands of kilometers of oil and gas pipelines, it is not easy to do a good job of inspection. However, now inspectors in many countries have welcomed a powerful assistant, that is, the growing pipeline inspection

guardian of oil and gas pipelines! The application of unmanned aerial vehicles for pipeline inspection has gradually become the norm

with the rapid advancement of urbanization and the accelerated development of Dongqing company in the transportation field and industrial manufacturing industry around the core key technologies that affect and restrict the production site, energy consumption is increasing. In order to further optimize the energy structure, reasonably allocate energy resources and improve the efficiency of energy transportation, countries have built a large number of oil and natural gas pipelines. As the national energy artery, the security of these pipelines is naturally very important

in the past, the maintenance and patrol of oil and gas pipelines were mostly carried out manually. However, due to the wide distribution of oil and gas pipelines and most of them in remote areas, manual inspection is time-consuming and laborious, and there are certain safety hazards. In case of natural disasters or accidents, the safety of oil and gas pipelines is often not known in time

especially with the increasing expansion of the energy industry, the process of oil and gas pipelines continues to grow, and the grinding surface loses its light, resulting in increasing pressure on manual inspection and maintenance. In order to improve the efficiency of oil and gas pipeline inspection, ensure the safety of oil and gas pipelines, and promote the application of science and technology has become an inevitable trend. Nowadays, the civil UAV industry is developing rapidly, and UAVs are gradually applied to the inspection of oil and gas pipelines, which is highly favored by energy enterprises

UAV assisted pipeline inspection has gradually become an often strict technical standard state

China's oil and gas fields are mostly located in the western region, and the imported pipelines are also mostly located in the West and North, so the oil and gas transmission pattern has always been dominated by the west east gas transmission and west east oil transmission. However, due to the large changes in terrain, different construction cycles, continuous growth of total mileage, and the possibility of damage by natural disasters and man-made damage, the demand for pipeline safety patrol and maintenance is becoming increasingly urgent

oil and gas pipelines are different from general pipelines. Once they are broken or damaged maliciously, it will not only cause huge property losses, but also threaten the life safety of surrounding people. Obviously, the traditional manual inspection mode can no longer adapt to the constantly changing reality. We must actively apply UAV and other technical equipment to better meet the growing needs of inspection and maintenance tasks

at present, China's Sinopec, CNOOC and other energy giants have used unmanned aerial vehicles for oil and gas pipeline inspection. Sinopec Northwest Oilfield not only uses unmanned aerial vehicles for daily patrol tasks, but also realizes night pipeline inspection; CNOOC Guangdong has actively built a 24-hour ground air integrated prevention and control system, and UAV assisted pipeline inspection has achieved phased results

in foreign countries, the application of unmanned aerial vehicles for pipeline inspection is also becoming the norm. Not long ago, French grtgaz company reached a cooperation with airmarine, which will build a natural gas pipeline cruise project, using unmanned aerial vehicles to assist in inspecting grtgaz's 80 km long natural gas pipeline in southern France

application advantages of pipeline inspection UAV

at present, in order to cope with many challenges brought by oil and gas pipeline inspection, energy enterprises and management departments in various countries have increased investment in the research, development and application of pipeline inspection UAV. Compared with the traditional manual inspection method, the inspection UAV equipped with professional equipment obviously has multiple advantages

first, the UAV can be carried and used flexibly, with strong mobility and fast flight speed. It can be separated from the influence of terrain, climate and other factors, cover a wide range of inspection areas, and reach places that are difficult for inspectors to reach, so as to greatly improve the efficiency of oil and gas pipeline inspection, save time and labor costs, reduce the safety risks of inspectors, and timely find, feed back and deal with emergencies

second, UAV is not only an inspection raider, but also an important data collection platform. The UAV can directly obtain the image of the inspection object or see that we have developed a dryer frequency information, and transmit it to the on-site inspection personnel or rear management personnel, technical experts, so as to provide an important reference for solving difficult problems and making comprehensive decisions. Moreover, the data collected by UAVs can form professional reports through accumulation and analysis, which is conducive to relevant enterprises to grasp the overall situation of oil and gas pipelines

at present, although the application of pipeline inspection UAV is still in the stage of popularization and has not yet achieved large-scale commercial use, with the upgrading of relevant technologies and the maturity of the market system, UAV will play an increasingly critical role in the field of oil and gas pipeline inspection and become a powerful assistant and guardian of oil and gas pipelines
