Analyzing the Innovation Progress in Global Oil and Gas Pipeline Transportation

Based on statistics and analysis of globally granted patents in the oil and gas pipeline sector, this study presents a panoramic view of the technological development and innovation evolution in oil and natural gas pipelines for relevant enterprises and engineers. Currently, China and Russia are increasingly dependent on oil and gas pipeline technologies and are very active in innovation activities. With large-scale oil and gas pipeline infrastructure development and numerous research teams actively participating in innovation, China has emerged as a major source of knowledge in global oil and gas pipeline technology innovation. Technologically, control, protection, or monitoring devices for oil and gas pipeline systems have become the most common technical theme in the oil and gas transportation. Additionally, pipeline inspection robots, support devices for pipelines, and heating or cooling technologies for pipelines also represent fields with promising innovation potential.
