The Importance of Oil and Gas Pipeline Leakage Monitoring

The transportation of oil and gas is generally carried out through pipeline transportation. Actualmente, pipeline transportation has become the main mode of transportation for hazardous substances such as oil and natural gas, as well as liquid materials. Especially after the adjustment of the national energy strategy and the successful operation of the West East Gas Pipeline Project, pipeline transportation has been widely used. Sin embargo, due to the large geographical span of transportation, especially in desert areas containing quicksand, the working environment is harsh, resulting in particularly severe pipeline losses and a generally lower service life than normal. This leads to problems such as pipeline exposure, desplazamiento, arching, retortijón, shearing, fuga, and even pipeline breakage, lo que resulta en incidentes cada vez más frecuentes en los oleoductos. Esto no sólo causa importantes pérdidas económicas a las empresas, pero también representa una gran amenaza para la vida de las personas, propiedad, y el medio ambiente. Obviamente, no es práctico que se produzcan problemas anormales durante el transporte por tubería., so for researchers, sólo pueden considerar desde la perspectiva de la prevención y el control, Monitoreo oportuno y eficiente de fenómenos anormales., and minimizing losses. Realizar análisis de tubería en la sección anormal de la tubería., obtain key information, determinar el modo de falla y el nivel de falla, y tomar medidas correctivas lo antes posible para remediar la falla.

¿Cuáles son los métodos para el monitoreo de tuberías basados en sensores distribuidos de fibra óptica and sound waves

Incluyendo los pasos de colocación. sensores distribuidos de fibra óptica en el área de monitoreo de tuberías, and installing acoustic sensing units at both ends of the pipeline or in sections on the pipeline, using distributed fiber optic sensors and acoustic sensing units to simultaneously monitor the pipeline in real time; The steps of configuring an optical power detection module for distributed fiber optic sensors and configuring a sound wave signal receiving and processing device for the sound wave sensing unit; The step of judging the leakage signal detected by the distributed fiber optic sensor and the acoustic sensing unit when the pipeline leaks. Monitor abnormal conditions of buried pipelines in desert areas due to sand dune movement, and visualize real-time monitoring of pipeline displacement, deformación, intrusión, exposición, arching, and leakage along the route; The use of distributed fiber optic vibration sensors and temperatura distribuida sensors for joint positioning and monitoring has the characteristics of more accuracy and efficiency; Distributed optical fiber is not limited by pipeline materials and can detect pipelines of all materials.
