Description
One, technical field: oil well three phase metering device is a kind of measuring apparatus that is used for oil well oil, gas, water.
Two, background technology: at present, the domestic separation vessel glass tube oil gauge that generally adopts, error in dipping is big.Adopt two-phase to separate the instrument metering method, the difficult control of separation vessel is made troubles to production management.
Three, summary of the invention: the purpose of this utility model is exactly, production management inconvenient phenomenon big at existing metering method error in dipping, proposes a kind of convenience, oil well three phase metering device accurately.Its technical scheme is: mainly by oil-gas separator be installed in gas-liquid import on the separation vessel and temperature transmitter, penetron, gas vent, liquid outlet, and the gas meter that is installed on the gas vent is formed with the liquid flowmeter that is installed on the liquid outlet, it is characterized in that: the gas-liquid import the inner in oil-gas separator is equipped with whirlwind flaring shunt and stabilier, in the inner, gas outlet the liquid level pressure control valve is installed.Described whirlwind flaring shunt comprises central authorities' inlet, whirlwind flaring tube, lamina tecti and the pipe composition of breathing hard that overflows, and central authorities' inlet is connected with the gas-liquid import, and whirlwind flaring tube is shape in the shape of a spiral.Described liquid level pressure control valve comprises valve seat, spool, valve body, air admission hole, positioning disk, valve rod, pivoted arm, rotating shaft, ball float and float connecting rod composition, valve body is communicated with gas vent and is fixed on oil-gas separator top, and ball float is fixed on rotating shaft by floating ball rod.The bottom external at oil-gas separator is equipped with blowoff valve, and the bottom is equipped with the two flanges of one group of pressure therein, at its top vent valve is installed.
The pressure control valve that the utility model adopts, the direct pilot-gas flow of discharging, the controlling liquid flow of discharging indirectly again, realization is to the control of liquid level and pressure; Whirlwind flaring separation vessel and stabilier can fully satisfy separating of gas and liquid.After oil-gas separator and gas meter, liquid flowmeter, temperature transmitter, the supporting installation of penetron, be connected control with computing machine, will be combined into the complete oil well three phase metering device of a cover, simplified equipment, compact conformation, reliable, failure-free operation for a long time need not maintenance.
Four, description of drawings:
Fig. 1 is one-piece construction figure of the present utility model;
Fig. 2 is the sectional view of the pressure control valve among Fig. 1;
Fig. 3 is the whirlwind flaring separation vessel decomposing schematic representation among Fig. 1.
Five, embodiment:
With reference to accompanying drawing 1, oil-gas separator comprises ectosome 5, gas-liquid import 8, gas outlet 13, liquid outlet 2, compositions such as door 27, supporter 28, blowoff valve 29, vent valve 30, whirlwind flaring shunt 10, stabilier 9, self-operated type liquid level/pressure control valve 12.Self-operated type liquid level/pressure control valve 12 is installed in the inner of oil-gas separator gas outlet 13.Whirlwind flaring shunt 10 and stabilier 9 are installed in the inner of gas-liquid import 8, and are fixed by fixed block 7 and 6.The two flanges 4 of one group of pressure are installed in the middle and lower part of oil-gas separator ectosome 5.
With reference to accompanying drawing 2, liquid level pressure control valve 12 comprises valve seat 15, spool 16, valve body 17, air admission hole 18, positioning disk 19, valve rod 20, pivoted arm 21, rotating shaft 22, ball float 1 and float connecting rod composition.Before normal liquid level was not set up, gas was through import 13 and from drain separator between the spool 16 opened and the valve seat 15.When rising to the scope of compromise lower limit gradually and continue, liquid level rises, ball float 1 drives float connecting rod 14 clockwise rotates rotating shaft 22, and drive pivoted arm 21 also clockwise rotates, valve rod 20 is upwards lifted, spool 16 turns down, and the tolerance of discharging from gas vent 13 reduces, and pressure rises gradually, after reaching the required pressure of discharge opeing, liquid level will be controlled on the height of design code.Then gas and liquid are distinguished drain separator.After this, if come tolerance, come liquid measure and defeated pressure to change outward, cause liquid level to rise or decline, self-operated type liquid level/pressure control valve 12 is under the effect of ball float 1 and float connecting rod 14, the capital is controlled at liquid level on the normal height, and pressure control on the required numerical value of discharge opeing.Liquid on the straight barrel in separation vessel 5 bottoms, was measured liquid aqueous rate and density with crude oil water content/densitometer detector before discharged liquid outlet 2, measure the temperature of liquid with temperature transmitter.With gas meter and liquid flowmeter, measure the gas flow and the fluid flow of drain separator respectively.The above-mentioned gas flow of measuring, signals such as the flow of liquid, density, water percentage, temperature, the input microcomputer through handling and computing, can get the output of producing well and production crew's oil, gas, water.
With reference to accompanying drawing 3, whirlwind flaring shunt comprises central authorities' inlet 23, whirlwind flaring tube 24, lamina tecti 25 and overflows pipe 26 compositions of breathing hard.Central authorities inlet 23 is connected with gas-liquid import 8, and whirlwind flaring tube 24 is shape in the shape of a spiral.Whirlwind flaring shunt 10 and stabilier 9 are installed on the inner of gas-liquid import 8, and on the top of whirlwind flaring shunt 10 gas outlet 11 are installed.Its central authorities inlet 23 is communicated with gas-liquid import 8, along whirlwind flaring tube 24 high speed rotating, obtains maximum centrifugal force, makes most gas collection to central, enters separation vessel top along overflow nipples 26, proceeds to collide and sedimentation separation; Liquid is along 24 downward mild the falling on the stabilier 9 of whirlwind flaring tube, and a small amount of remaining gas is further separated out, and then liquid is mild drops down bottom into separation vessel, and remaining minor diameter bubble is further upwards separated out.Crude oil water content/density tester and temperature transmitter are installed in the testing conduit 4 of bottom of oil-gas separator 5 cylindrical shells, before the liquid drain separator, finish the measurement of crude oil water content, density and temperature.
This measuring apparatus has gas liquid high-efficiency and separates air capacity, lifting rate, the control of pressure and liquid level, the multiple functions such as detection of crude oil water content, density and temperature.It is the guardian technique of this utility model.With gas meter, the supporting installation of liquid flowmeter, the complete oil well three phase metering device of a cover will be combined into.
