Description
Technical field
The invention provides a kind of distributed monitoring leak from oil gas pipe system, belong to automatic control technology field.Especially distributed optical fiber Raman temperature sensor and peripheral unit is utilized to carry out the monitoring of oil and gas pipeline leakage, for the normal operation of oil and gas pipes provides safety guarantee.There is good economic benefit and social benefit.
Technical background
Energy industry is the basic industry of national economy, is also technology-intensive industries.China's production of energy amount and consumption figure all at the forefront in the world, wherein oil and natural gas accounts for greatly 30% of total energy consumption.Oil and natural gas is the energy of relative clean compared with coal, so the oil gas energy obtains comparatively faster development in recent years.By in October, 2013, the oil and gas pipes total length of China has reached 10.6 ten thousand kilometers, estimates will reach 150,000 kilometers in 2015.
But the security situation of Oil & Gas Storage is always comparatively severe.The accident taken place frequently and the casualty numbers constantly risen, also become the shade along with Chinese Petroliferous plumbing installations high speed development.PetroChina Company Limited. supervisor's magazine " Chinese Petroleum Enterprises " publishes the article title, and according to incompletely statistics, from nineteen ninety-five to 2012 year, various pipes security incident more than 1000 occurs altogether in the whole nation.Cause a tremendous loss of lives and huge property loss, the major coal accidents causing great ecocatastrophe happens occasionally, and these accidents have had a strong impact on economic construction and social stability.
For the yellow Pipeline Leak explosive accident in east of the Qingdao occurred recently " 11.22 " China Petrochemical Industry, cause that 62 people are wrecked, 136 people are injured altogether, road and a large amount of building of several kilometers are damaged, and substantial oil enters sea.Except economic loss cannot be estimated, the environmental nuisance caused may need the time of decades to eliminate.And this time the initial reason of accident is only Pipeline Leak.
No matter traditional oil and gas pipeline leakage detection method is artificial line walking, inner detection, or external detection, all needs the longer response time, usually between 1 hour to one day.Like this, even if found leakage, but also may cause larger loss.So be badly in need of a kind of efficient, real-time oil and gas pipeline leakage on-line measuring device, and distributed optical fiber temperature sensor can be competent at the equipment of this task just.
Summary of the invention
The object of this invention is to provide a kind of distributed monitoring leak from oil gas pipe system, Raman scattering sensed system can monitor the temperature of multiple spot on an optical fiber simultaneously, and optical time domain reflection technology can be utilized to carry out space orientation to temperature field, positioning precision can reach 1 meter.
Distributed optical fiber Raman temperature sensor is by the high-acruracy survey of temperature on sensor fibre optical cable and reference optical fiber optical cable, contrast and analysis is carried out to temperature, judge temperature anomaly point in time, i.e. contingent oil and gas leakage point, thus leakage point is positioned; Measurement time is short, continuous measurement no-blind area; Quick response is without sluggishness; The precision that is quick on the draw is high; Accurate addressing location is accurate.Send local sound, visual alarm when temperature exceeds setting value, remind operator on duty to note; Started by peripheral interface that fire-protection equipment carries out lowering the temperature, fire-fighting work; Remote alarm signal can also be launched by peripheral interface.
Beneficial effect: the signals collecting that a kind of distributed monitoring leak from oil gas pipe system changes pipe temperature is faster, and react sensitiveer, to the more accurate positioning of leakage point, spatial resolution is higher.One root optical fiber can be monitored the temperature of multiple spot simultaneously, and optical time domain reflection technology can be utilized to carry out space orientation to temperature field.Based on the oil and gas pipeline leakage system of distributed optical fiber Raman temperature sensor, temperature measurement time is short, continuous measurement no-blind area; Quick response is without sluggishness; The precision that is quick on the draw is high; Accurate addressing location is accurate.Greatly reduce the possibility of the accident such as fire, blast because of oil and gas pipeline leakage initiation, in commercial Application, have vast application prospect, there is good economic and social benefit.
