The Importance of Oil and Gas Pipeline Leakage Monitoring
The transportation of oil and gas is generally carried out through pipeline transportation. Currently, 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. بهرحال, 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, displacement, arching, twisting, shearing, leakage, and even pipeline breakage, resulting in increasingly frequent pipeline incidents. This not only causes significant economic losses to enterprises, but also poses a huge threat to people’s lives, property, and the environment. It is obviously impractical for abnormal problems to occur during pipeline transportation, so for researchers, they can only consider from the perspective of prevention and control, timely and efficient monitoring of abnormal phenomena, and minimizing losses. Conduct pipeline analysis on the abnormal pipeline section, obtain key information, determine the fault mode and fault level, and take remedial measures as early as possible to remedy the fault.
What are the methods for pipeline monitoring based on distributed fiber optic sensors and sound waves
Including the steps of laying distributed fiber optic sensors in the pipeline monitoring area, 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, deformation, intrusion, exposure, arching, and leakage along the route; The use of distributed fiber optic vibration sensors and distributed temperature 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.
