Method for determining spilled oil diffusion range of oil pipeline on high and steep slope and calculation system

Abstract

The invention provides a method for determining an oil spill diffusion range of a high and steep slope oil pipeline and a calculation system, and the method comprises the steps: determining basic data of an area where a target pipe section of the oil pipeline is located, the seepage distance of the oil product in the vertical direction after spilled oil diffusion happens to the target pipe section and the oil spilling area and the oil spilling distance of the oil product along the surface of the mountain land are calculated, and the oil spilling area and the oil spilling distance of the oil product along the surface of the mountain land are calculated through a ZM model; and according to the seepage distance, the oil spilling area and the oil spilling distance of the oil product, the control range of oil spilling diffusion of the target pipe section is determined. The system for calculating the oil spill diffusion range of the high and steep slope oil pipeline can realize the method for determining the oil spill diffusion range of the high and steep slope oil pipeline. The method has the advantages of being high in calculation accuracy, convenient to use on site, capable of planning and making management decisions according to the change situation of soil of different types of high-consequence pipe sections on the whole oil conveying pipeline and the like.

Description

technical field [0001] The invention relates to the technical field of oil pipeline protection, in particular to a method and a calculation system for determining the oil spill diffusion range of an oil pipeline on a high and steep slope. Background technique [0002] In recent years, many oil and gas pipelines in my country have been put into operation one after another, and the number is increasing rapidly. Their safe operation plays a decisive role in the development of national life and economy. However, it is not difficult to find that the China-Myanmar oil and gas pipeline under the jurisdiction of the Southwest Pipeline Company is the "main artery" that ensures the smooth operation of the social economy. The China-Myanmar oil and gas pipeline crosses the Hengduan Mountains, the Yunnan-Guizhou Plateau, crosses international rivers such as the Lancang River and the Nujiang River, and passes through many fourth-level areas. When the rainy season comes, geological disaste...

AI Technical Summary

Problems solved by technology

In addition, the China-Myanmar pipeline is also facing the following problems: (1) The contradiction between local economic development and pipeline protection is prominent; (2) There is no effective detection method for the complex stress of the pipeline; (3) The inspection method is difficult to meet the requirements of weld quality control. Social and technical problems and the special geological and hydrological conditions of the China-Myanmar pipeline seriously threaten the safe operation of the China-Myanmar pipeline; (4) Large terrain fluctuations: there are many large-drop pipeline sections, and the oil leakage distance is long and the scope of influence is large

[0004] To sum up, there is no calculation method for the oil spill range of high and steep slope oil pipelines in the prior art, and there is no pipeline control method based on the calculation of oil spill range. The calculation method of the impact area of ​​the oil spill in the consequence area can effectively intercept and rescue the oil spilled in the pipeline, reduce the pollution of the water, soil and vegetation in the environment by the oil spilled in the pipeline, and improve the control efficiency of the oil pipeline
