Abstract
The utility model discloses a gas-liquid separator of an oil field single-well metering device. Calibers of two end openings of an expanding pipe are reduced and cone-shaped, a pressure spraying nozzle is arranged at the upper end of the interior of a separation tank, the pressure spraying nozzle is communicated with the expanding pipe, and the top portion of the separation tank is communicated with a gas phase pipeline. The gas phase pipeline is communicated with a gas phase outlet, an upper liquid level switch and a lower liquid level switch are arranged on the upper side wall of the separation tank, and a pump is communicated with the bottom of the separation tank through a liquid phase pipeline, and the liquid phase pipeline is communicated with a liquid phase outlet. Two liquid level switches and the pump are respectively connected with a controller through cables. When the gas-liquid separator conducts gas-liquid separation for mixed liquid generated by an oil field single well, the structure of combining of separation of the expanding pipe, impacting and separation of the pressure spraying nozzle and exhausting decompression and separation of the pump is applied. The gas-liquid separator overcomes the defects that in the prior art, a popular single-well is not thorough in metering gas-liquid separation and the like and has the advantages of being wide in flow range, thorough in gas-liquid separation and the like.
Description
Technical field
The utility model is a kind of metering device gas-liquid separator of oil field individual well metering usefulness, the particularly improvement of structure of gas liquid separator.
Background technology
The oil field individual well metering is an important process in the field production management, measures accurately oil well is grasped the oil reservoir situation, formulates production decision, has important directive significance.What mainly adopted in each oil field at present is cyclone separation device, utilizes effect divided gas flow and the liquid of centrifugal force; But this device is in actual use because every mouthful of well situation is different, even same well is at different time, and its fluid is all different with the situation of giving vent to anger, that have in addition the fluctuation very large, therefore, its gas-liquid separation is abundant not, often can not produce a desired effect, cause measuring unstable.
The utility model content
In order to overcome not fully defective of prior art oil field individual well metering gas-liquid separation, the utility model provides a kind of novel gas-liquid two-phase separator, can be applicable to widely range of flow, and gas-liquid two-phase is separated.
A kind of oil field individual well metering gas-liquid separation device, it is characterized in that: the bore of convergent divergent channel two-port dwindles, and is tapered; The knockout drum inner upper end is equipped with pressure nozzle, and pressure nozzle is communicated with convergent divergent channel; The knockout drum top is communicated with the gas phase pipeline; Gas phase pipeline communication gaseous phase outlet;
Lateral wall at knockout drum is provided with upper and lower two liquid-level switches;
In the bottom of knockout drum, be communicated with pump by liquid pipe; Liquid pipe is communicated with liquid-phase outlet;
Two liquid-level switches, pumps connect controller by cable respectively.
When the utility model was used, the oil field individual well inlet pipeline was communicated with the convergent divergent channel other end.Operating principle of the present utility model is, the first step, and the production fluid that comes from oil field individual well reduces pressure by convergent divergent channel, carries out the gas-liquid separation first time.Second step adopts pressure nozzle, and mixture is dispersed as molecule, accelerates separating rate in the gas from liquid; The 3rd step, adopt pump control tank internal pressure, when liquid level arrived upper liquid-level switch, controller started pump automatically, extracted mixed liquor in the knockout drum out, relied on environment under low pressure, reduced gas solubility, and gas is fully separated; When liquid level arrived lower liquid-level switch, controller stopped pump automatically, and the liquid level of knockout drum is by upper and lower liquid-level switch automatic controlling liquid level; The action in above-mentioned the 3rd step is carried out repeatedly, reaches the purpose of gas, liquid separation.After oil field individual well output mixed liquor used this separator to carry out gas-liquid separation, oil-water mixture entered liquid pipe, and gas enters the gas phase pipeline, entered respectively the metering of next stage.
The utility model is when carrying out gas-liquid separation to oil field individual well output mixed liquor, used convergent divergent channel separation, the separation of pressure nozzle bump to take out pressure release with pump and separate the structure that combines, the shortcomings such as present popular one-well metering gas-liquid separation is not thorough have been overcome, the advantages such as it is wide to have range of flow, and gas-liquid separation is thorough.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Liquid-level switch on 1 inlet pipeline, 2 convergent divergent channels, 3 knockout drums, 4 pressure nozzles, 5 controllers, 6 gas phase pipelines, 7 liquid pipes, 8 pumps, 9,10 times liquid-level switches, 11 liquid-phase outlets, 12 gaseous phase outlets.
The specific embodiment
A kind of oil field individual well metering gas-liquid separation device, it is characterized in that: the bore of convergent divergent channel 2 two-port dwindles, and is tapered; Knockout drum 3 inner upper end are equipped with pressure nozzle 4, and pressure nozzle 4 is communicated with convergent divergent channel 2; Knockout drum 3 tops are communicated with gas phase pipeline 6; Gas phase pipeline 6 is communicated with gaseous phase outlet 12;
Lateral wall at knockout drum is provided with upper and lower two liquid-level switches 9,10;
In the bottom of knockout drum, be communicated with pump 8 by liquid pipe 7; Liquid pipe is communicated with liquid-phase outlet 11;
Two liquid-level switches, pumps connect controller 5 by cable respectively.Controller can adopt conventional prior art.
The utility model specific works process: when the utility model was used, oil field individual well inlet pipeline 1 was communicated with the convergent divergent channel other end.The production fluid that comes from oil field individual well enters convergent divergent channel 2 by import 1 and carries out the gas-liquid separation first time, and after low-pressure gas-liquid separated for the first time, portion gas entered gas phase pipeline 6 from rear rising of pressure nozzle 4 ejections.
During residual mixed liquor process shower nozzle, shower nozzle is dispersed as molecule with gas-liquid mixture, the speed that can accelerate to separate in the gas from liquid like this, thus realize for the second time gas-liquid separation, and the portion gas of separating for the second time enters gas phase pipeline 6 from rear rising of shower nozzle ejection.
Residual mixed liquor out drops to knockout drum 3 afterwards from shower nozzle, mixed liquor constantly increases in the knockout drum 3, liquid level constantly rises, when liquid level arrives upper liquid-level switch 9, upper liquid-level switch 9 signals of controller 5 by collecting start pump 8 automatically, and the liquid of knockout drum 3 is pumped out, pressure moment of knockout drum 3 diminishes, and impels the gas in the mixed liquor to separate fully in the process of pressure release.Mixed liquor in the knockout drum 3 is pumped away and enters liquid pipe 7; Liquid level descends, and is same when liquid level arrives lower liquid-level switch 10, the stopping of controller 5 automatic control pumps 8.In the process that liquid level rises, the pressure in the knockout drum 3 increases simultaneously, and gas is squeezed into gas phase pipeline 6 in this process.Liquid level repeatedly rises and falls in the knockout drum 3 like this, impels the gas in the mixed liquor fully to separate, thereby realizes for the third time gas-liquid separation.
