By means of the intelligent evaluation method for the integrity of the oil-gas pipe network, the integrity level of the oil-gas pipe network can be efficiently and accurately evaluated, a favorable theoretical basis is provided for maintenance of the oil-gas pipe network, and the safety and reliability of the oil-gas pipe network can be ensured.

Description

technical field [0001] The invention relates to a method for evaluating the integrity of a pipeline network, in particular to an intelligent method for evaluating the integrity of an oil and gas pipeline network based on a Gabor wavelet neural network optimized by an improved chicken flock algorithm. Background technique [0002] The construction process of oil and gas pipelines continues to deepen and has become the main transmission system for oil and gas energy. The number of lines of oil and gas pipelines continues to increase, and the safety problems of oil and gas pipelines are also becoming more and more prominent. During the operation of the pipeline, there are many risk factors, including pipeline manufacturing defects, welding defects, mechanical damage, soil corrosion, medium corrosion, etc. After long-term operation, the degree of damage to the pipeline will increase, and in severe cases, leakage and explosion will occur. Resulting in economic losses and casualt...
