Description
Technical field
The application is related to crude oil transmission apparatus field, more particularly to a kind of crude oil pipeline drop measurement device.
Background technology
The description of this part only provides the background information related to disclosure, without forming prior art.
In oil field ground technique, crude oil transmission flow is in occupation of highly important status.Oilfield enterprise generally can be to original
The pressure drop parameter of oil-piping is measured to grasp the running situation in oil field, ensures the safe and highly efficient operation in oil field.Specifically, pipe
Road pressure drop can reflect pipeline fluid flow inside situation, the consumption of computer tube stream energy, tube wall deposit thickness etc..And oil field
Enterprise can find operation problem in time according to the unusual change of pressure drop, adjust operating condition.Therefore accurate measurement gathering line
Pressure drop it is particularly important for oilfield enterprise.
Oil field manufacturing enterprise usually uses gauge measurement piping loss at present, is drawn by being set at gathering line first and last end
Hole is pressed to measure piping loss.However, due to the complicated characteristic of crude oil, crude oil very likely occurs in crude oil pipeline
Depositional phenomenon.Once crude oil sedimentary occurs, it can not only cause the valid circulation area of pipeline to reduce, can more cause table tracting pressuring hole
Block.Tracting pressuring hole once block, it will cause the failure of drop measurement equipment so that measurement result with actual result deviation compared with
Greatly, cause to be difficult to the condition of production is monitored and handled by the voltage drop value of measurement, had a strong impact on the safe operation of pipeline.
And block part is cleared up, it could be carried out only when pipeline is overhauled or stops managing defeated operation, so as to add
The expense and human cost of operational management are taken.
Especially current China's major part oil field all comes into the production later stage, and moisture content increases in oil field produced thing
Add.Pipeline medium is high water-content crude oil, and the difference of profit density make it that oil-water stratified flow moves in pipeline, and crude oil is straight with tube wall
Contact.Compared in general crude oil pipeline, the pipeline Crude Oil for conveying high water-content crude oil is more likely formed crude oil in motion and sunk
