Description
Technical field
The utility model belongs to the device of oilfield multiphase flow metering, the more particularly to improvement to its structure.
Background technology
The oil-water-gas three-phase metering device that existing oil field individual well metering is used, mostly starts pump to discharge in knockout drum
Liquid.Because pump is chronically at operating condition, so often breaking down, and usually to repair, change, not only cost increases
Plus, and influence gas-liquid separation is not thorough, and measuring accuracy is low.The oil-water-gas three-phase metering device of this structure in use, consumes
Electric rate is also very high, has accordingly increased cost payout.
The content of the invention
In order to overcome the defect of existing product, the utility model provides a kind of new oil-water-gas three-phase metering mechanism.
A kind of oil-water-gas three-phase metering device, it is characterised in that knockout drum sets imported valve, and bottom is sequentially communicated
Mass flowmenter, liquid non-return valve, outlet valve；Bottom connects blowoff valve by the liquid mouth of pipe, and gas-liquid separation tank top passes through
The gas mouth of pipe connection ultrasonic flowmeter, ultrasonic flowmeter connection cooling gas check valve, cooling gas check valve connection outlet valve；Gas-liquid
Knockout drum inner chamber sets big ball float；Ball float net buoyancy>100N；
Ultrasonic flowmeter, mass flowmenter connect constant setpoint controller by cable respectively.
The utility model is simple in construction, the big ball float control completely in knockout drum, and ball float is in self gravitation and liquid
Under the buoyancy of body, the control of height of liquid level in knockout drum can be achieved, while equipped with constant setpoint controller, can read in real time
The signals such as liquid level, pressure, temperature, oil-water-gas three-phase flow are taken, and all of above signal and data are handled；With other controls
Form processed is compared, the scheme controlled using big ball float, and without the movable member such as motor-driven valve and pump, being floated upwards by ball float to close
Hold one's breath the body mouth of pipe, now liquid is pressed down away naturally, therefore can cancel pump, and being floated downwards by floating ball component can closing liquid
The mouth of pipe, now liquid flowing cut-out, it is not necessary to increase motor-driven valve in addition to cut off liquid flowing, greatly reduce the failure of equipment
Rate, while the control mode is purely mechanic control, eliminates automatically controlled produced program error and electronic component failure is produced
The possibility of raw problem, it is safer reliable；Simultaneously because having lacked electronic component, the effect of energy-conserving and environment-protective is served.
Brief description of the drawings
Accompanying drawing 1 is the utility model structural representation.
1 imported valve, 2 knockout drums, 3 ball floats, the 4 liquid mouths of pipe, the 5 gas mouths of pipe, 6 ultrasonic flowmeters, 7 mass flows
Meter, 8 safety valves, 9 constant setpoint controllers, 10 cooling gas check valves, 11 liquid non-return valves, 12 outlet valves, 13 blowoff valves, 14 pressure
Table, 15 locating dowels.
Embodiment
A kind of oil-water-gas three-phase metering device, knockout drum 2 sets imported valve 1, and bottom is sequentially communicated mass flow
Meter 7, liquid non-return valve 11, outlet valve 12；Bottom connects blowoff valve 13 by the liquid mouth of pipe 4, and gas-liquid separation tank top passes through
The gas mouth of pipe 5 connection ultrasonic flowmeter 6, ultrasonic flowmeter connection cooling gas check valve 10, cooling gas check valve connection outlet valve；
Knockout drum inner chamber sets big ball float 3；Ball float net buoyancy>100N；Ball float net buoyancy=ball float buoyancy-floating ball component weight.
Ultrasonic flowmeter, mass flowmenter connect constant setpoint controller 9 by cable respectively.
Described ball float realizes that transverse shifting is spacing by least three locating dowels 15, and locating dowel two ends are fixed on gas-liquid point
From on inwall above and below tank inner chamber.
It can be accurately positioned to ensure that ball float fluctuates, it is effective to close and open the liquid mouth of pipe 4 and the gas mouth of pipe 5, can
At least three locating dowels 15 are set, and locating dowel 15 is that locating dowel 15 is welded in knockout drum along every 120 degree one of ball float one week
Fixed in 2；For whole system safety, knockout drum top sets pressure gauge 14, and top sets safety valve 8.
Gas-liquid mixture is entered by imported valve 1, gas-liquid separation is then carried out in knockout drum 2, now liquid in tank
Position is low, and ball float 3 blocks the liquid mouth of pipe 4 due to deadweight, and gas gas mouth of pipe 5 above knockout drum is discharged, by ultrasonic flowmeter 6
Flow measurement is carried out, gas flow data uploads to constant setpoint controller 9；When the liquid of knockout drum 2 reaches certain altitude, float
Buoyancy suffered by ball 3 is more than deadweight, and ball float is floated, and the liquid mouth of pipe 4 is opened, and liquid is carried out by following pipeline by mass flowmenter 7
Simultaneously upstream data signal is to constant setpoint controller 9 for flow measurement and oil-water ratio measurement, and then gas and liquid combine together again row
Go out；When liquid moment carrys out amount greatly in knockout drum 2, liquid level rises, and ball float 3 continues to float up to the closing gas mouth of pipe 5, makes liquid level
Decline, all circulated until recovering air-liquid.
