Description
Technical field
The utility model relates to a kind of Crude Oil Transportation detecting instrument, in particular, is a kind of seabed oil transmission line stolen detection device.
background technique
At present, increase along with marine petroleum exploitation amount, depend merely on pleasure boat transportation and cannot meet conveying needs, therefore pipeline under the ocean becomes the main path of remote conveying crude oil gradually, due to ocean platform and land distant, therefore off-shore pipeline is generally laid apart from larger, oil transport pipeline is buried in seabed again, residing environment is conventionally complicated and changeable and cannot estimate intuitively, this steals oil to lawless person chance is provided, monitoring means mainly relies on pressure sensing technology to judge at present, because pipeline distance is large, pressure parameter changes not obvious, if small flow stolen, just be difficult to monitor, and the variation of leakage point or fluid can not be detected in time, cannot locate accurately leakage point or stolen position.
Due to crude oil pipeline borough chief apart from conveying, crude oil mixed liquor cognition becomes three bed boundarys to flow gradually, separation gas, crude oil, water from top to bottom successively, exactly because this feature, the punching of stolen molecule destroys generally from the top of pipeline, to punch steals oil, in the process of draining the oil, first gas overflow, thereby cause oil-water interfaces to rise.Therefore, utilize this feature a cheap performance simple in structure of design and reliable oil level detecting device for detecting having very important significance of stolen.
Summary of the invention
The utility model is intended to solve the technical deficiency that existing pressure sensing detection mode exists, for the separation characteristic of crude oil in submerged pipeline, provide a kind of have structure simple and direct rationally, detect accurate and highly sensitive, can accurately to locate leakage point seabed oil transmission line and steal and survey detection device.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of seabed oil transmission line stolen detection device, special way is to comprise the petroleum pipeline 1 that is embedded in seabed, and be positioned the flotation device 2 on sea, described flotation device 2 is built-in with signal transmitter 2-1, and between the emitter antenna 2-2 that described signal transmitter 2-1 carries by it and ground base station, signal and communication is connected; Between described flotation device 2 and described petroleum pipeline 1, draw and be provided with for locating the connecting body 3 of described flotation device 2; Described petroleum pipeline 1 inner shaft is to being laid with several upright post type sensor base 4, wherein each upright post type sensor base 4 is longitudinally stood the inside of being located at described petroleum pipeline 1, and interval is provided with several liquid level sensors 5 on its column, between the signal transmitter 2-1 of described flotation device 2 inside and the liquid level sensor 5 of described petroleum pipeline 1 inside, via submerged cable 6, be electrically connected to and carry out the transmission of signal;
Described connecting body 3 can be connect steel wire or connecting band, and its quantity can arrange one or arrange as required a plurality of;
In order to reduce wave, the impact of submerged cable 6 is pullled, described submerged cable 6 and described connecting body 3 are tied together by fixing cingulum;
The laying quantity of described upright post type sensor base 4 and the distance of being separated by can arbitrarily be set according to actual needs, and the distance between two adjacent upright post type sensor base 4 can be in the scope of 100-300 rice;
The quantity of described liquid level sensor 5 is determined according to the diameter of different petroleum pipelines, and the distance between two adjacent liquid level sensors 5 can be at 3-8 centimetre.
A kind of seabed of the utility model oil transmission line stolen detection device, reasonable in design is simple and direct, use safe and reliable, gas, crude oil, the water three-decker state of the utility model based on crude oil mixed liquor body, utilize level sensing technology, and binding signal transmitter is connected with the communication between ground base station, can the variation by oil liquid level leakage point be detected in the very first time, and according to the specified place that is laid in different local transmitters and accurately locates leakage, compare with traditional Pressure testing mode, there is the many advantages such as timely, accurate, efficient.
