Abstract
An oil well three-phase metering device is characterized in that on the basis of a traditional tipping bucket type flow meter, an oil cavity liquid level apparatus 6 is installed at internal upper part of a shell 10, and a float valve 13 is installed at the middle part thereof; the bottom part of the shell 10 is processed into a water cavity 16; and a water cavity liquid level apparatus 11 is installed between the water cavity 16 and the shell 10. The oil well three-phase metering device has the advantages of simple structure, convenient installation and reliable work, can be used for metering the single well production of oil wells, and can significantly improve the liquid metering accuracy compared with the tipping bucket type flow meter, simultaneously carry out the moisture content measurement, directly calculate the oil production rate, and facilitate the production management.
Description
Technical field:
The utility model relates to the use tricks device of volume production amount of a kind of oil field, especially for the oil well three phase metering device of one-well metering.
Technical background:
Before the utility model; each oil field adopts the tipping bucket type flow meter to carry out the metering of oil well output more; because this device is to be the basis of converting with the gravitational method; change and produce through the metered media water-bearing amount of regular meeting and air content than mistake; liquid measure after its metering also need be carried out the mensuration of moisture content simultaneously; could converse the oil production of oil well individual well at last, make troubles to production management.
Summary of the invention:
The purpose of this utility model is: for the metering of oil field individual well output provides a kind of oil well three phase metering device, because this device is on traditional tipping bucket type flow meter basis, the level gauging and the volumetric water content measurement function of oil-water mixture have been increased, not only can improve the well yield measuring accuracy, also can be according to the measurement of water-content coefficient result, directly converse oil production, made things convenient for production management.
The purpose of this utility model realizes by following measure: a kind of oil well three phase metering device, comprise thermometer, pressure gauge, gas flowmeter, gas outlet, safety valve, eliminator, liquid trap, tipping bucket, shell, inlet, liquid outlet, sewage draining exit, and have in the jar shape shell of thermometer, pressure gauge, gas flowmeter, gas outlet, safety valve and inlet, liquid outlet, sewage draining exit eliminator, liquid trap, tipping bucket also are installed, it is characterized in that the shell internal upper part is equipped with radar type oil pocket liquid level instrument, the middle part is equipped with float valve; Water cavity is processed in the bottom, and radar type water cavity liquid level instrument and connecting pipeline are installed between water cavity and shell internal upper part.
The utility model is simple in structure, easy for installation, and reliable operation is used for oil well well yield metering, can obviously improve the liquid volume measurement precision than the tipping bucket type flow, and can carry out measurement of water-content coefficient simultaneously, directly converses oil production, has made things convenient for production management.
Description of drawings:
Fig. 1 is the structural representation of oil well three phase metering device.
The specific embodiment:
A kind of oil well three phase metering device, comprise thermometer 1, pressure gauge 2, gas flowmeter 3, gas outlet 4, safety valve 5, eliminator 7, liquid trap 8, tipping bucket 9, shell 10, inlet 12, liquid outlet 14, sewage draining exit 15, and have in the jar shape shell 10 of thermometer 1, pressure gauge 2, gas flowmeter 3, gas outlet 4, safety valve 5 and inlet 12, liquid outlet 14, sewage draining exit 15 eliminator 7, liquid trap 8, tipping bucket 9 also are installed, shell 10 internal upper parts are equipped with radar type oil pocket liquid level instrument 6, the middle part is equipped with float valve 13; Shell 10 inner bottom parts are processed into water cavity 16, and between water cavity 16 and shell 10 internal upper parts radar type water cavity liquid level instrument 11 and connecting pipeline are installed.
The operating principle and the using method of oil well three phase metering device are: this device is installed between oil well measurement locates earlier, be that inlet 12 connects the individual well production flow line, liquid outlet 14 connects petroleum pipeline, gas outlet 4 connection gas transmission lines (or emptying), water cavity 16 planted agents are full of water, liquid outlet 14 and are under float valve 13 effects and close shape, just can open the well yield metering that inlet 12 carries out oil well this moment.Three-phase mixed liquor from oil well is in inlet 12 enters shell 10, and contained gas can pass through eliminator 74 discharges from the gas outlet at its top under the effect of gravity, and carries out the metering of gas production by thermometer 1, pressure gauge 2, gas flowmeter 3; Through the oil-water mixture of inlet 12 from oil well, after then falling into tipping bucket 9 meterings by liquid trap 8, fall into bottom gathering in the shell 10 again, in the regulation unit interval, the liquid level lifting height that accumulates in bottom oil-water mixture in the shell 10 by 6 pairs in oil pocket liquid level instrument is measured, and just can converse the individual well production fluid amount (with reference to tipping bucket 9 metering results) of this oil well; At this moment, also can measure,, obtain profit liquid level H, water liquid level h, oil density γ simultaneously again according to oil pocket liquid level instrument 6 measurement results by 11 pairs of shells of water cavity liquid level instrument, 10 inner bottom part water cavities, 16 middle water level liquid level lifting heights
Oil, water density γ
Water, and moisture content by volume
Then can converse the oil output per well of this oil well according to the result of moisture content calculating.
