Description
Technical field
The utility model relates to oil-gas metering device in oil exploitation process, specifically the automatic servicing unit of a kind of gauging.
Background technology
Gauging is important process of oil gas metering, but along with oil field is continually developed, oil well gas production reduced year by year, after having measured oil, need first liquid level in metering device to be gone out by gas compression, because the little reason of gas causes liquid level discharge slower, cannot grasp individual well production fluid amount every day, to the measure of production, bring impact, cause closing away well oil well simultaneously and stop well time lengthening, affect oil well output, reduce rate while recovering the oil.
Summary of the invention
The purpose of this utility model is to provide a kind of gauging automatic servicing unit, the narrow-minded fast-descending that also can realize metering device liquid level of oil well.Reduce pipeline internal pressure or reduce crude oil loss, avoid polluting progressive expansion.Shortening is closed away well and is stopped the well time, increases oil well well yield.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, the automatic servicing unit of a kind of gauging, comprise interconnective tubing pump, metering device, described tubing pump has tubing pump import and tubing pump outlet, tubing pump import connects metering device outlet line by tubing pump inlet line, described tubing pump inlet line and metering device outlet line junction arrange inlet valve, between described inlet valve and tubing pump, electromagnetic valve is set, described tubing pump outlet is connected with the outlet line of metering device by tubing pump outlet line, tubing pump outlet line is being disposed with outlet valve and bypass valve towards metering device direction.
On described metering device, be provided with content gauge, described tubing pump is also connected with motor.
Also comprise control device, the upper and lower side of described content gauge arranges respectively top Magnetic Sensor, bottom Magnetic Sensor, and described electromagnetic valve, motor, top Magnetic Sensor, bottom Magnetic Sensor are all connected with control device.
Described control device comprises PLC controller and is connected to motor switch circuit, less electromagnetic valve switch circuit, top magnetic sensor signal receiving circuit, the bottom magnetic sensor signal receiving circuit on PLC controller.
Described motor is connected with motor switch circuit, and described electromagnetic valve is connected with less electromagnetic valve switch circuit, described top Magnetic Sensor and top magnetic sensor signal receiving circuit, described bottom Magnetic Sensor and bottom magnetic sensor signal receiving circuit.
Compared to prior art, the utlity model has following beneficial effect:
(1) control cabinet can be realized the unlatching of delivery valve and pump automatically, reduces labor intensity.
(2) the narrow-minded fast-descending that also can realize metering device liquid level of oil well.
(3) reduce pipeline internal pressure or reduce crude oil loss, avoiding polluting progressive expansion.
(4) shorten and to close away well and stop the well time, increase oil well well yield.
When the complete oil of metering device amount, its internal liquid need be discharged, when tolerance is not enough, start pump operation, meanwhile, electromagnetic valve is opened automatically, and liquid is discharged, and metering device liquid level is reduced to lower graduation mark.When liquid level sensor obtains signal, transfer to control cabinet, pump is shut down, it is comprised of pump terminal valve, tubing pump, electromagnetic valve, liquid level sensor, control cabinet etc.The automatic servicing unit of gauging is installed on flow line, automatically realizes the start and stop of pump according to the variation of liquid level.Meanwhile, when individual well perforation maybe needs to put cleared-out oil pipeline overbottom pressure, can manually open pump, pipeline internal pressure or crude oil are expelled to main pipe line.
