The "Infrared Holographic Sensing Oil and Gas Pipeline Intelligent In-Detection Instrument" project, developed by the Research and Development Innovation Center of Shenyang Institute of Instrument Science, Liaoning Province, has won first place in the national finals of the China Innovation Method Competition. The team, led by Song Huadong, Ma Yinan, and Wang Zhongwei, also received multiple other awards for their groundbreaking work.
Oil and gas pipelines are often referred to as the "energy bloodline" of a country, playing a crucial role in the national economy. In-pipe inspection is an internationally recognized method for ensuring pipeline safety. However, before this innovation, China's oil and gas pipeline monitoring market was dominated by foreign companies from Europe and the United States. This not only came with high service costs—approximately 3 million yuan per 100 kilometers—but also posed serious risks, as sensitive information such as pipeline operation details and geographic coordinates could be exposed, threatening national security.
Recognizing the potential in the field of intelligent pipeline detection, the Shenyang Institute's R&D center adopted an inter-enterprise cooperation model to secure funding for its research. While working on intelligent internal inspection technology for terrestrial pipelines, the team also focused on marine in-service oil and gas pipelines. They jointly applied for a major scientific research instrument development project with Northeastern University and CNOOC Energy Development Equipment Technology Co., Ltd., which was successfully approved by the National Natural Science Fund.
Through continuous research, the Shenyang Institute has made significant progress in applying "three-axis magnetic flux leakage and pulse eddy current composite heterogeneous field detection technology" for detecting wall defects in oil and gas pipelines. Their efforts have focused on breakthroughs in electromagnetic holographic imaging technology, pipeline robot integration, positioning systems, and defect evaluation. These innovations have enabled the successful development of an intelligent holographic sensing oil and gas pipeline inspection instrument.
The first National Finals of the China Innovation Method Competition were co-sponsored by the China Association for Science and Technology, the Ministry of Science and Technology of China, and the Hunan Provincial People’s Government. With the theme “Innovative Entrepreneurship, Method First,†150 teams from 32 regional competitions participated, representing 39 industries including machinery, electronics, materials, chemicals, new energy, and transportation. The competition aimed to identify and promote outstanding innovative projects and teams.
Innovation methods refer to effective theories, techniques, and tools that people develop through practical activities in invention creation, scientific research, or problem-solving. This competition aims to encourage scientific and technological workers to innovate more actively, promote the broader and deeper application of innovative methods, and drive development through innovation.
