The specific embodiment
A kind of individual well three-phase metering mechanism is characterized in that,
The bore of convergent divergent channel 14 two-port dwindles, and is tapered, and an end is communicated with the mixed liquor inlet tube 15 of well head, and the other end is communicated with tapered cyclone separator 11, and one time the convergent divergent channel top is communicated with quadratic extension pipe 8;
Tapered cyclone separator 11 is fixed in fluid reservoir 13 inner chamber tops, is communicated with a convergent divergent channel 14;
Bottom at the top of storage tank interior cyclone separator is provided with umbellate form oil-gas separating plate 12;
Lateral wall at fluid reservoir is provided with upper and lower two liquid-level switches 9,10;
In the bottom of fluid reservoir, be communicated with successively control valve 5, mass flowmenter 2 and mixture export pipe 16 by liquid pipe 6;
Two liquid-level switches, gas duplex rotor meter 1, mass flowmenter 2, control valves 5 connect controller 3 by cable respectively.
Be provided with safety valve 7 at the top of fluid reservoir.
The specific works process:
Individual well output mixed liquor at first enters a convergent divergent channel 14 from mixed liquor inlet tube 15 and carries out the expansion separation first time, gas, the heavy difference of liquor ratio, in the container of a sudden enlargement, flow velocity reduces rear in the process that main flow turns to, trickle drop sinks and separated from the gas in the gas, the gas upwelling is once expanded separation to quadratic extension pipe 8 again according to primary principle; The gas of separating rises and enters gas phase pipeline 4, and isolated liquid falls to entering tapered cyclone separator 11.The mixing material of separating by convergent divergent channel 14 simultaneously also enters tapered cyclone separator 11.
The mixed liquor that enters tapered cyclone separator 11 carries out rotational flow separation next time again, liquid is at tapered cyclone separator 11 High Rotation Speeds, the ratio of oil is great to flow downward at tube wall, and specific gravity of gas gently upwards flows in the middle of tapered cyclone separator, forms centrifugal force separate; Isolated gas rises and enters equally quadratic extension pipe 8, once expands equally again separation.
Mixed liquor after the process rotational flow separation falls bump umbellate form oil-gas separating plate 12 at Action of Gravity Field, forms bump and separates, and isolated gas rising enters quadratic extension pipe 8 and expands separation.
Mixed liquor has entered fluid reservoir 13 after above-mentioned separation, after liquid level reached liquid-level switch 9 in the fluid reservoir 13, controller 3 was opened control valve 5 automatically, and liquid flows out from liquid pipe 6, and container inner pressure diminishes, and mixed liquor is isolated gas; After liquid level arrives lower liquid-level switch 10, controller 3 closed control valves 5; Controller 3 is by the switch of the level switch signal valve of feedback.Above-mentioned action reaches the purpose of gas, liquid separation repeatedly.
Liquid is through mass flowmenter 2 online density and the quality of surveying oil, water after expansion separation, eddy flow centrifugation, baffle plate bump separate, and liquid enters the next stop through mixture export pipe 16.
The gas that separates through quadratic extension pipe 8 enters gas duplex rotor meter 1 through gas phase pipeline 4, and gas duplex rotor meter 1 is measured the volume of gas; Gas is measured by mixture export pipe 16 and is entered the next stop.
Each instrument signal carries out acquisition and processing by controller 3, obtains the related datas such as liquid level in separator switching signal, individual well liquid outlet quantity, oil-containing, moisture, gassiness, temperature; So far finish the three phase metering of oil field individual well oil, gas, water.Controller 3 can adopt conventional PLC control module.
