Embodiment 1

[0024] With the wave of urbanization, for places that used to belong to the suburbs, due to the change of town planning, the original pipelines have been on the ground or there are already ground buildings, the excavation of artificial rivers and the manufacture of artificial landscapes, causing stress around the pipelines to occur. Variety. The multiple factors of human activities, especially infrastructure and farming or unintentional exploration activities, have caused various terrain and landform changes around the oil pipeline. This series of activities makes the original assessment of oil pipeline risk factors, which are limited to the corrosion factors of the pipeline itself, unable to accurately reflect the actual risk.

[0025] Based on engineering practice, we found that with the popularity of automobiles and mobile tools, the analysis of traffic and traffic knowledge, combined with the investigation of oil pipeline risks, we believe that traffic volume and traffic a...

Abstract

The invention discloses a quantitative analysis method for leakage of an oil pipeline. Traffic passing factors and communication factors are fused to reflect risks, the above parameters are applied tothe proposed probability model for fitting normal distribution, and the risk of the network oil pipeline is differentially evaluated through the risk probability fitting model in combination with topographic factors according to the mapped communication traffic parameters and traffic volume parameters for representing the risk of the oil pipeline, so that the rapidity and accuracy of risk evaluation are improved.

Description

technical field [0001] The invention relates to the field of oil and gas pipeline transmission, and is specifically applicable to a method for quantitative risk assessment of oil pipelines. Background technique [0002] Long-distance oil pipeline refers to the pipeline used to transport semi-finished crude oil or refined oil between the storage warehouse in the production area and the user unit. It plays an increasingly important role in the construction of the national economy. With the rapid development of my country's economy and With the substantial improvement of people's living standards, the number of pipeline users and the scale of the pipeline network are constantly increasing. However, the information management technology of oil pipelines in most pipeline companies has not improved accordingly. There may be varying degrees of damage in each case. [0003] In the existing technology, there are various qualitative or quantitative risk assessment methods. However, var...
