An oil storage tank is fixed on the truck, and a wire separation metering device is fixed on the truck; the on-line separation metering device consists of a tank-shaped cyclone separator, a gas flowmeter, a mass flowmeter, an inlet valve, an outlet valve and a pipeline. An inlet valve is fixed on an inlet pipeline of the tank-shaped cyclone separator, and a separated gas outlet of the tank-shaped cyclone separator is connected with a gas flowmeter through a pipeline; the separated liquid outlet of the tank-shaped cyclone separator is connected with a mass flow meter through a pipeline, the outlet pipelines of the gas flow meter and the mass flow meter are connected together through a tee joint, and the other end of the tee joint is connected with an outlet valve. The other end of the outlet valve is connected with an oil storage tank through a pipeline. The effect is as follows: the normal oil collecting process of the oil-gas mixture produced by the oil well in the oil well metering process by the pressure of the oil well is realized.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly a kind of oil well daily fluid production rate, water content metering device are a kind of oil well metering devices of movable type.
Background technology
In oil field development, reason causes oilwell produced fluid amount normally not measure owing to measurement flow imperfection, measuring equipment fault, metering cycle be inaccurate etc.Usually adopt the movable metering device of oil well to measure, as portable individual well three phase separation continuous metering device.To be a kind of novel packaged type carry out the device of three phase separation continuous metering to individual well or many mouthfuls of oil wells to portable individual well three phase separation continuous metering device, its maximum feature is all to be installed in workplace, three phase separator, flow process and parts such as measuring instrument and support on the motor vehicle, this device measuring accuracy height, mobility is good, can realize the simplification of the layout of oil and gas gathering system, operation in the open air throughout the year reduces the production investment cost greatly.
But this metering device adopts the volumetric method metering, because this metering device oil storage volume is limited, usually after 1～2 mouthful of oil well of metering, crude oil is full of this metering device, must carry out emptying to unloading oil drop, therefore one-well metering unloads oil require driving in 1～2 hour distance, and the one-well metering underaction is motor-driven, has increased the traffic safety risk simultaneously.
The utility model content
The purpose of this utility model is: a kind of portable oil well quality metering device is provided, can realize that oilwell produced fluid amount accurately measures, overcome the movable metering device of conventional oil well and must carry out emptying, unload oil require driving in 1～2 hour distance, the drawback that has security risk in the emptying process makes that crude oil can advance normal oil-collecting flow process in the oil well online activity metering process.
The technical solution adopted in the utility model is: portable oil well quality metering device, and mainly by the ON-LINE SEPARATION metering device, truck, fuel reserve tank and flexible pipe are formed, and it is characterized in that: be fixed with fuel reserve tank on truck, fix wired separate measurement device on truck; The ON-LINE SEPARATION metering device is made up of jar shape cyclone separator, gas flowmeter, mass flowmenter, imported valve, outlet valve and pipeline.Be fixed with imported valve on the suction line of jar shape cyclone separator, the divided gas flow outlet of jar shape cyclone separator has pipeline to connect gas flowmeter; The separating liquid outlet of jar shape cyclone separator has pipeline quality of connection flow meter, and the outlet line of gas flowmeter and mass flowmenter links together by threeway, is connected with outlet valve at the other end of threeway.The other end of outlet valve has pipeline to connect fuel reserve tank, and fuel reserve tank has outlet line.Be mainly used in low permeability oil field stripper well simple wellhead production metering of oil wells.Oil well produced next gas mixture carries out gas-liquid separation by jar shape cyclone separator in the metering process, isolated liquid carries out liquid measure, moisture metering by mass flowmenter, gas measures by gas flowmeter, and the gas after the metering mixes laggard normal flow mutually with liquid.
Described ON-LINE SEPARATION metering device is fixed on the top of fuel reserve tank.
Sketch the portable oil well quality metering device course of work.Consult Fig. 1.Stop well recovery earlier, close well head and produce gate 1, single amount gate 3, infiltrate gate 4, open emptying gate 5 and carry out emptying; Take well head then apart and produce the union 2 that valve 1 connects, union 2 is connected on the inlet line of ON-LINE SEPARATION metering device 6 by flexible pipe.Open during metering and produce gate 1 and infiltrate gate 4, close emptying gate 5.The outlet line of ON-LINE SEPARATION metering device 6 is connected the suction line of infiltrating gate 4 by flexible pipe.Then, start oil pumper and recover the oil, oil well produced mixture enters portable oil well quality metering device and measures.The gas mixture of metering back oil well output carries out the oil-collecting flow process by the pressure of oil well.In metering process, because at the last fuel reserve tank 8 that is fixed with, can store oil well produced mixture, and oil well produced mixture can be transported in time in the gathering line, do not influence the process of metering.
The beneficial effects of the utility model: the portable oil well quality metering device of the utility model, be connected to well head by middle pressure flexible pipe in the metering process, realize that the gas mixture of oil well output in the oil well measurement process leans on the pressure of oil well to carry out normal oil-collecting flow process.Compare with the movable metering device of original volumetric method, do not need emptying after the metering, one-well metering reduces by 1～2 hour emptying driving distance, can carry out the activity metering for a long time between well group, has flexible characteristics.
