Description
Technical field
The present invention relates to Oil-Gas Storage and Transportation Engineering underground oil storage cave depot monitoring of leakage technical field, especially a kind of leakage oil
On-Line Monitor Device.
Background technology
Underground oil storage cave depot is influenced by geological conditions and sealing structure defect, and in the operation phase, there may be certain storages
Oil leaks, and oil can be caused largely to lose when serious and endanger surrounding enviroment.
It is artificial to obtain water sample in monitoring holes at present by drilling on oil depot periphery in order to find the oil of leakage, take back reality
It tests in room analysis water and whether there is petroleum components, and then judge whether that Oil spills occurs.
Since that there are efficiency is low, big to water sample interference, human cost is high, cannot achieve real time on-line monitoring etc. for manual method
Deficiency, industry is interior, and there is an urgent need to find a kind of automatic on-line monitoring means.
The sensor monitored on-line to the oil in water sample generally uses optical means, specific by being irradiated to water sample
Light beam, analyze incident light 21 and differentiate whether contain oil in water sample by the emergent light 23 of water sample 22, basic principle is shown in
Fig. 1.
Current sensor operating principles are shown in that Fig. 2, this sensor 18 are directly anchored to water pipeline by ring flange 32
31 side walls are only applicable to be monitored the flowing flow 33 in water pipeline 31, the water sample monitoring being directly used in monitoring holes,
Following problem can be faced:
1. since the water body in monitoring holes is almost without mobility, there is lamination in water body in leakage petroleum components,
Oil sensor sensing face 17 is more difficult to touch petroleum components;
2. in the water body for lacking mobility in the wild, biology and mineral deposition, deposit are easy tod produce as the time increases
Being gathered in 17 surface of oil sensor sensing face can extreme influence measurement effect;
3. current operative sensor alleviates impurity by being equipped with electric cleaning brush wiping oil sensor sensing face 17
Aggregation or adherency, since cleaning brush needs to apply larger pressure and torque, the driving of cleaning brush to oil sensor sensing face
Axis is needed across sensor housing, and water power isolation is difficult, and the raising of sealing performance and water-resistant pressure to sensor is very
It is unfavorable, deep percolation oil in monitoring holes monitoring position often 100m or more under water, the sensing with electric cleaning brush at present
Device is difficult to meet water-fast pressure request;
The completion 4. monitoring holes are once constructed, peripheral optical environment are difficult to change, and sensor is easy by ambient light interference
And it influences to measure.
5. the water surface curve in monitoring holes will appear certain fluctuation by Effect of Underground Water Level, it is enriched in the petroleum components of the water surface
It also will appear variation in height, the fixed sensor in position is difficult to obtain true measurement result.
The presence of the above problem causes oil sensor to cannot be used directly for the leakage oil monitoring in monitoring holes, at present still
Manual method can only be used.
In order to realize that underground oil storage cave depot leaks the on-line monitoring of oil, need a kind of to can adapt to environment in monitoring holes
Monitoring device.
