Abstract
Disclosed is a single-well metering device. A mixture inlet is communicated with a reducer. A reed switch liquid level meter, an electric contact pressure gauge and a visible glass tube level meter are arranged on the outer wall of a separation tank, a safety valve is arranged at the top, and a drainage valve is arranged at the bottom. A measurable gas flow meter is communicated with the top of the separation tank through a gas phase pipe, and a mass flow meter is communicated with the bottom of the separation tank through a liquid phase pipe. The device is characterized in that a primary cyclone separation pipe and a secondary cyclone separation pipe which are in a tapered structure are arranged on the upper portion of an inner cavity of the separation tank and are arranged vertically, and inner cavities of the primary cyclone separation pipe and the secondary cyclone separation pipe are communicated. The reducer is communicated with the primary cyclone separation pipe and the secondary cyclone separation pipe respectively. According to the device, multiple cyclone separation, heating separation and gas-liquid flow adjustment structures are used for prompting gas and liquid to be separated from the mixture fully, and accordingly, accurate metering of single-well three phases of oil, gas and water of the oil field is achieved.
Description
Technical field
The present invention is the heterogeneous metering device of a kind of oil field individual well, the particularly improvement to its structure.
Background technology
A separating cyclone tube is only housed in the knockout drum chamber of existing single well metering device, and it measures on gas phase and liquid phase pipeline without control valve.The shortcoming of this single well metering device structure is that a separating cyclone tube can cause gas-liquid separation thorough not; Knockout drum is positioned at outdoor, and under natural conditions, the temperature of knockout drum changes with the variation of natural temperature, if outside air temperature is lower, and the easy condensation of pot liquid, the gas-liquid separation effect of mixed liquor is just undesirable.Moreover different oil well gas-liquid ratio difference are very large, if on gas phase and liquid phase pipeline without control valve, this single well metering device just cannot be applicable to the oil well of different gas-liquid ratios.This single well metering device that at present oilfield uses has caused one-well metering oil, gas, water not accurate enough.
Summary of the invention
In order to overcome the defect of prior art, the present invention adopts a kind of improved single well metering device, can be applicable to range of flow widely, and more thoroughly makes gas-liquid two-phase separate.
A kind of single well metering device, mixed liquor import is communicated with reducer pipe, is provided with tongue tube content gauge, electro connecting pressure gauge, visual glass-tube liquid level meter, electric contact thermometer on knockout drum outer wall, and top is provided with safety valve, and bottom is provided with blowoff valve; Can survey gas flowmeter 9 and be communicated with knockout drum top by gas phase pipeline; Mass flowmenter is communicated with knockout drum bottom by liquid phase pipeline;
It is characterized in that, knockout drum inner chamber top is provided with separating cyclone tube, swirl flow separator tube; Separating cyclone tube and swirl flow separator tube are all tapered structure, and two pipes arrange up and down, and inner chamber is communicated with;
Reducer pipe is communicated with respectively separating cyclone tube and swirl flow separator tube.
Can be communicated with control valve by gas phase pipeline at the entrance point that can survey gas flowmeter; The entrance point of mass flowmenter can be communicated with control valve by liquid phase pipeline.When application, can regulate according to concrete situation the size of gas-liquid flow by control valve, therefore this single well metering device is just applicable to the oil well of different gas-liquid ratios.
Bottom at knockout drum arranges electric heater, and an electric contact thermometer is set on the outer wall of knockout drum.Can use electric heater according to the difference of outside temperature like this, accelerate gas separating rate, guarantee that gas-liquid separation is thorough.
It is unstable that the present invention has overcome current popular single well metering device metering, the shortcomings such as gas-liquid separation is not thorough, adopted repeatedly rotational flow separation, added thermal release, the structure such as gas-liquid Flow-rate adjustment, impel gas-liquid fully to separate from mixed liquor, thereby reach the object to oil field individual well oil, gas, the accurate measurement of water three-phase; And can be applicable to air content height various oil wells not etc., there is applied range.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is that the present invention uses control structure schematic diagram.
1 mixed liquor import, 2 reducer pipes, 3 electric heaters, 4 tongue tube content gauges, 5 electro connecting pressure gauges, 6 visual glass-tube liquid level meters, 7 electric contact thermometers, 81 control valves, 82 control valves, 9 can be surveyed gas flowmeter, 10 blowoff valves, 11 mass flowmenters, 12 separating cyclone tubes, 13 swirl flow separator tubes, 14 knockout drums, 15 safety valves, 16 gas phase pipelines, 17 liquid phase pipelines, 18 controllers.
specific embodiment mode
A kind of single well metering device, mixed liquor import 1 is communicated with reducer pipe 2, on knockout drum 14 outer walls, be provided with tongue tube content gauge 4, electro connecting pressure gauge 5, visual glass-tube liquid level meter 6, electric contact thermometer 7, top and be provided with safety valve 15, bottom is provided with blowoff valve 10; Can survey gas flowmeter 9 and be communicated with knockout drum 14 tops by gas phase pipeline 16; Mass flowmenter 11 is communicated with knockout drum 14 bottoms by liquid phase pipeline 17; In the bottom of knockout drum 14, electric heater 3 is set.
Reducer pipe 2 is communicated with respectively separating cyclone tube 12 and swirl flow separator tube 13.
Be communicated with control valve 81 at the entrance point that can survey gas flowmeter 9 by gas phase pipeline 16; Entrance point at mass flowmenter 11 is communicated with control valve 82 by liquid phase pipeline 17.
Specific works principle of the present invention:
Oil gas aqueous mixtures enters into reducer pipe 2 from mixed liquor import 1 and expands separation, and the gas containing liquid after separation enters into separating cyclone tube 12 one time, carries out rotational flow separation at this; Isolated gas rises, and enters gas phase pipeline 16; Isolated liquid drops to swirl flow separator tube 13 and carries out rotational flow separation again, and the gas of separating rises, and enters gas phase pipeline 16, and isolated liquid drops to the bottom of knockout drum.
In above-mentioned separation process, to expand the isolated liquid containing gas from reducer pipe 2 and enter swirl flow separator tube 13 and carry out rotational flow separation, isolated liquid drops to the bottom of knockout drum, and isolated gas enters gas phase pipeline 16.
The above-mentioned liquid of separating enters mass flowmenter 11 through liquid phase pipeline 17 by control valve 82 and measures.The above-mentioned gas of separating is entered and can be surveyed gas flowmeter 9 and measure by control valve 81 through gas phase pipeline 16.
When the present invention applies, can survey gas flowmeter 9, mass flowmenter 11, electric heater 3, tongue tube content gauge 4, electro connecting pressure gauge 5, electric contact thermometer 7 and all be connected with controller 18 by circuit.
