In recent years, the frequency of oil and gas long-distance pipeline accidents in our country is higher and higher, posing new challenges to its safety and reliability. Therefore, an accident risk assessment and analysis technology for long-distance oil and gas pipelines has been established to improve pipeline safety. Firstly, this paper briefly introduces the related contents of risk and risk assessment. According to the types of risk assessment, this paper presents risk analysis methods such as tree model and data model, analyzes and sorts the risk of oil and gas long-distance pipeline accidents, promptly puts forward protective measures, Minimize the number of accidents and serious consequences.
