Description

The continuous self-measuring device of eliminator oil gas
Technical field
The utility model relates to oil recovery technique field, oil field, particularly a kind of oil gas metering device that is applied to oil field oil recovery measuring station.
Background technology
At present, the eliminator metering is adopted in the oil and gas production of old filed measuring station metering now.The structure of eliminator metering device is: be made up of gs-oil separator and flow meter.Gs-oil separator is a vertical tank, and vertical tank has a suction line and two outlet lines.On the outlet line on top, be equipped with one and cross air lock door and a gas flowmeter, an oily gate of mistake is installed on the outlet line of bottom.Method of measurement is: the well liquid of producing well output contains the gentle gs-oil separator vertical tank that enters of oil and carries out Oil-gas Separation.When needs measure, closed oily gate, open the survey air lock door, the record liquid level rising used time of certain altitude, calculate the unit interval gas production.The volume of output liquid is the production fluid amount of this this time of well in the time of oiling, and the tolerance of output is measured the flow of the gas of this time period by gas meter after eliminator separates.The shortcoming of the method is height and the time that must be risen by oil recovery worker on-the-spot record liquid level, and during one-well metering, the workman can not leave and will prevent also that simultaneously liquid level is too high, causes metering separator to build the pressure and the potential safety hazard that produces.The deficiency that exists is:
After a bite well had measured, refluence Cheng Kaiguan gate six times measured a bite well down again, and the program complexity causes employee's operate miss easily, and potential safety hazard exists.
The metering time is short, measures if exist when fuel-displaced intermittence of oil well, and there is very mistake in the accuracy of data admission.
Existing equipment is undergone technological transformation, adopt modern automation control equipment metering oil and gas production, at least several ten thousand, at most tens0000, costly.
The utility model content
The purpose of this utility model is: provide a kind of eliminator oil gas continuous self-measuring device, reach continuous metering, reduce error, improve the data admission accuracy of oil well.Alleviate working strength of workers, increase work efficiency, the purpose that eliminates safe hidden trouble.
The technical solution adopted in the utility model is: the continuous self-measuring device of eliminator oil gas is made up of gs-oil separator and flow meter.Gs-oil separator is a vertical tank, and vertical tank has a suction line and two outlet lines.On the outlet line on top, be equipped with one and cross air lock door and a gas flowmeter, an oily gate of mistake is installed on the outlet line of bottom.It is characterized in that: a fluid flowmeter is installed on the outlet line of bottom.Article two, the end of outlet line has a upright pipeline to be communicated with, and upright pipeline is connected with an oil gas vent.Even and between the oil gas vent liquid level equilibrium control device is arranged at upright pipeline.
In order to improve the well liquid temp, improve the flowability of well liquid, improve the sensitivity of fluid flowmeter, on the outlet line of bottom, be enclosed with electric heater and attemperator.
Be communicated with by upright pipeline in two outlet line ends of eliminator vertical tank, realize liquid gas continuous partial flow Balance Control liquid level.According to law of connected vessels, described liquid level equilibrium control device is that the entrance height scope is in the altitude range that the vertical tank content gauge can show; The height of the oil gas vent that connects is below the altitude range that the vertical tank content gauge can show.
Method is: the liquid oil-containing of producing well output is gentle to be entered the metering separator vertical tank by suction line and carries out Oil-gas Separation, and the oil gas vent pipeline connects outer petroleum pipeline.Cross the fuel tap door and cross air lock door and all be in opening, in vertical tank after the Oil-gas Separation, the liquid measure of the pressure differential fluid flowmeter operation record output that liquid level rising certain altitude produces and control liquid level automatically; The isolated gas of vertical tank is through air lock door and gas flowmeter, and the tolerance of record output writes down the metering time simultaneously.Fluid flowmeter and gas flowmeter flow are exactly this well yield in this time period.Because liquid gas continuously flows into and flows out the continuous self-measuring device of eliminator oil gas, avoided building the pressure in the metering separator vertical tank and the potential safety hazard that produces, can realize the work purpose of unattended continuous metering.
The continuous self-measuring device of this eliminator oil gas does not influence original metering method, to some exceptional wells such as well large-minded, that yield poorly, can measure the time method that oils with manually on duty yet.
Adopt dual mode metering oil and gas production simultaneously, when equipment breaks down, can not influence the accuracy of admission data.
The beneficial effects of the utility model: this device energy continuous metering oil well oil and gas production, operation sequence is simple, and maintenance of equipment is convenient, has eliminated potential safety hazard; Can reduce the fuel-displaced error in dipping of oil well, increase work efficiency and precision.Behind the continuous metering of oil well, by the two people metering of a measuring station, change the touring metering of two stations, one people or three stations, one people into, work efficiency improves three to six times.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
