Study on Safety Evaluation of Oil and Gas Pipeline Based on Unascertained Measure Theory

Abstract

As one of the basic supply systems to maintain the normal operation of cities, oil and gas pipelines are directly related to social stability and economic development, and are the lifeblood of cities. In view of the lack of discussion on oil and gas pipeline leakage prediction and the deficiency of related evaluation methods in China, this paper evaluates the safety of oil and gas pipelines based on the previous research results and the unascertained measure theory as the core. Combined with the unascertained measure model, the factors affecting the safety of oil and gas pipelines are systematically analyzed and evaluated. According to the engineering practice of an oil pipeline, the measured data are collected, the safety evaluation index is determined, and the model is used to calculate and solve the example, and the safety level of seven sections of the pipeline is evaluated. After investigation and inspection, the evaluation results are in line with reality. This method aims to evaluate the safety of oil and gas pipelines more effectively and provide the basis for relevant departments to take safety measures.
