Distributed fiber optic sensors and acoustic pipeline monitoring-INNO

The Importance of Oil and Gas Pipeline Leakage Monitoring

The transportation of oil and gas is generally carried out through pipeline transportation. Pada masa ini, 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. Namun begitu, 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, anjakan, arching, twisting, shearing, kebocoran, and even pipeline breakage, mengakibatkan insiden saluran paip semakin kerap. Ini bukan sahaja menyebabkan kerugian ekonomi yang ketara kepada perusahaan, tetapi juga menimbulkan ancaman besar kepada kehidupan orang ramai, property, and the environment. Jelas sekali tidak praktikal untuk masalah abnormal berlaku semasa pengangkutan saluran paip, jadi untuk penyelidik, mereka hanya boleh mempertimbangkan dari sudut pencegahan dan kawalan, pemantauan yang tepat pada masanya dan cekap terhadap fenomena abnormal, dan meminimumkan kerugian. Menjalankan analisis saluran paip pada bahagian saluran paip yang tidak normal, mendapatkan maklumat penting, tentukan mod kerosakan dan tahap kerosakan, dan mengambil langkah-langkah pembaikan seawal mungkin untuk membetulkan kesalahan.

Apakah kaedah pemantauan saluran paip berdasarkan pengesan gentian optik yang diedarkan dan gelombang bunyi

Termasuklah langkah-langkah meletakkan pengesan gentian optik yang diedarkan di kawasan pemantauan saluran paip, 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, ubah bentuk, pencerobohan, exposure, arching, and leakage along the route; The use of distributed fiber optic vibration sensors and suhu teragih 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.
