How to apply distributed fiber optic sensing in oil pipelines-INNO

The application of optical fibers in pipelines

Saluran pipa adalah fasilitas transportasi material yang penting untuk sistem penting seperti gas alam, minyak, pemanasan perkotaan, dan gas. Ini sangat penting bagi perkembangan perekonomian nasional dan transportasi energi dan material. Pada saat yang sama, fasilitas pipa mempunyai investasi yang besar dan sebagian besar terletak di parit atau terkubur di bawah tanah. Mereka memiliki tingkat penyembunyian tertentu di ruang angkasa. Jika rusak karena sebab manusia atau alam, sulit untuk mendeteksinya secara tepat waktu. Kebocoran bahan yang mudah terbakar dan meledak akan menimbulkan bahaya keselamatan yang besar. Jika hal ini menyebabkan kecelakaan kebakaran atau ledakan, hal ini akan membawa kerugian ekonomi yang sangat besar, dan bahkan menimbulkan banyak korban jiwa dan kekacauan sosial.

The existing pipeline monitoring methods can only be disposed of by monitoring the pressure changes in pipeline sections or detecting problems such as pipeline deformation or leakage. Karena itu, pipeline disposal is mostly after an event has occurred, which has caused certain consequences. Saat ini, there is no reliable technical measure for effective monitoring of pipeline accidents in the early stage. If existing monitoring devices such as electromagnetic sensors are used, pipeline leakage may cause safety accidents such as fires or explosions, and it is not possible to achieve comprehensive monitoring of the entire pipeline. Karena itu, it is necessary and urgent to develop a comprehensive and timely monitoring system and method that is less prone to other adverse reactions with pipeline media.

Itu fiber optic monitoring device for pipeline vibration can monitor and analyze municipal pipelines such as natural gas in real time, and can realize the detection and warning of natural gas pipeline infringement events and the detection and analysis of damage and leakage points. Including induction devices, sensing devices, monitoring controllers, and warning devices; The sensing device is fixed on the pipeline, and the sensing device includes fiber optic cables laid along the pipeline and clamps used for installing fiber optic cables and forming a fixed connection with the pipeline; The sensing device includes a vibration collector for monitoring the vibration of fiber optic cables and a fiber optic thermometer for monitoring the temperature changes of fiber optic cables; The vibration collector and fiber optic thermometer are both connected to the monitoring controller signal, which is connected to the warning device signal and transmits warning information and sends warning commands to the warning device.

Sistem Pengukuran Suhu Serat Optik Terdistribusi Pipeline Fiber Optic Leakage Technology

The advantages of pipeline transportation are obvious, and people’s production and life are already inseparable from pipelines. Namun, due to the corrosion of the natural environment and transportation medium, defects in materials and construction, as well as the impact of human excavation damage and natural disasters such as earthquakes, pipelines may experience leaks, ledakan, and even explosions. Besides considering the serious economic losses caused by pipeline leakage or explosion, it can also cause the leakage of harmful substances, pollute the environment, and even lead to poisoning and explosion accidents, endangering personal safety. Karena itu, early leakage monitoring of pipelines, as well as early warning of geological hazards, mechanical and manual construction, and even malicious damage to pipelines, drilling and theft that endanger pipeline safety, are particularly important. The traditional leakage monitoring methods cannot monitor pipeline leaks, let alone determine the location and area of the leakage point, and cannot provide real-time monitoring and early warning for various natural disasters, mechanical operations, and human operations that endanger pipeline safety. Selain itu, the shortcomings of existing technologies in monitoring pipeline safety hazards include: point sensors, which cannot meet the needs of long-distance pipeline safety monitoring; Sensors require power supply and are not suitable for leak monitoring in flammable and explosive pipelines.

Itu fiber optic composite pipeline and its monitoring system solve the problem of existing technologies being unable to implement pipeline leakage monitoring, pipe burst and excavation damage warning. It can fully cover long-distance pipelines, without monitoring blind spots in time and space, Dan serat optik terdistribusi sensors are passive. It solves the problem of no power supply along long-distance pipelines, is not affected by electromagnetic and lightning interference, has good monitoring effect, high monitoring accuracy, and accurately locates the location of safety hazards. The fiber optic unit can simultaneously monitor the leakage, getaran, and strain of pipelines, and the composite judgment of multiple monitoring results improves the accuracy of pipeline warning.
