Description
Technical field
This application involves crude oil transmission apparatus field more particularly to a kind of crude oil pipeline drop measurement devices.
Background technique
The description of this part only provides and discloses relevant background information to the application, without constituting the prior art.
In oil field ground technique, crude oil transmission process is in occupation of highly important status.Oilfield enterprise usually can be to original
The pressure drop parameter of oil-piping is measured to grasp the operating condition in oil field, guarantees the safe and highly efficient operation in oil field.Specifically, pipe
Road pressure drop is able to reflect pipeline fluid flow inside situation, the consumption of computer tube stream energy, tube wall deposit thickness etc..And oil field
Enterprise can find in time operation problem according to the unusual variation 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 the setting at gathering line first and last end
Hole is pressed to measure piping loss.However, very likely will appear crude oil in crude oil pipeline due to the characteristic of crude oil complexity
Depositional phenomenon.Once crude oil sedimentary occurs, it can not only make the valid circulation area of pipeline reduce, table tracting pressuring hole but will be caused
Blocking.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 that the condition of production is monitored and is handled by the voltage drop value of measurement, seriously affected the safe operation of pipeline.
And block part is cleared up, it only just can be carried out when pipeline is overhauled or stops managing defeated operation, to increase
The expense and human cost of operational management are taken.
Especially current China's major part oil field all comes into the production later period, and moisture content increases in oil field produced object
Add.Pipeline medium is high water-content crude oil, and the difference of grease density moves oil-water stratified flow in pipeline, and crude oil is straight with tube wall
Contact.Compared to general crude oil pipeline, the pipeline Crude Oil for conveying high water-content crude oil is more likely formed crude oil during exercise and sinks
The measurement of lamination, pressure drop is more difficult.
