Comprehensive oil and gas pipeline leakage monitoring system

Abstract

A comprehensive oil and gas pipeline leakage monitoring system mainly comprises infrasonic wave sensors, an acoustics monitoring terminal, a clock server and a leakage monitoring server; two infrasonic wave sensors are mounted at each of an upstream detecting point and a downstream detecting point of a pipeline that needs monitoring; an infrasonic wave signal is generated when the pipeline leaks; whether leakage occurs or not can be judged through comparing the infrasonic wave signal with normal background noise; the infrasonic wave sensors preprocess and amplify the collected infrasonic wave signal generated due to leakage of the pipeline, convert the collected infrasonic wave signal into a multichannel sound wave signal of the numeric field, and transmit the multichannel sound wave signal to a signal acquisition and analysis system; and the signal acquisition and analysis system determines the leakage position according to the difference of time when the infrasonic wave signal reaches the upstream detecting point and the downstream detecting point and the propagation velocity data of a sound wave in a fluid. The comprehensive oil and gas pipeline leakage monitoring system adopts the clock server to solve the time synchronization problem of upstream monitoring equipment and downstream monitoring equipment and provides time marks for all data.

Description

technical field [0001] The invention relates to a comprehensive monitoring system for leakage of oil and gas pipelines, which can locate the leakage positions of gas, liquid and multiphase flow pipelines, thereby reducing the impact on pipeline transportation. Background technique [0002] Sonar technology was first invented by the British Navy in 1906. It has a history of more than 100 years. Sonar is the main technology used by navies for underwater surveillance. It is used to detect, classify, locate and track underwater targets; Underwater communication and navigation, to ensure the tactical maneuvering of ships, anti-submarine aircraft and anti-submarine helicopters and the use of underwater weapons. In addition, sonar technology is also widely used in torpedo guidance, mine fuze, fish detection, offshore oil exploration, ship navigation, underwater operations, hydrographic survey and survey of seabed geology and landforms. In addition to the military field, sonar tech...
