Description
Technical field
The utility model relates to a kind of measuring apparatus, the specifically multistage cyclone gas-liquid two three phase metering device that is separated.
Background technology
From the output object that oil well comes out, be a kind of heterogeneous fluid that mixes by crude oil, sewage, rock gas etc., these multiphase mixtures are exactly that our the said three-phase that is mixed by Oil, Water, Gas flows.Wherein oil phase is meant the liquid hydrocarbon in the oil well output object; Gas phase is meant rock gas, lighter hydrocarbons, non-light hydrocarbon gas etc.; Water then is meant mineralized water, also has a spot of solid phase sometimes, as sand, wax, hydrate etc.
Our customary way is at present, and the Oil, Water, Gas three-phase mixed liquor with each oil well is transported in the common metering separator respectively, measures the flow of each phase fluid of after separating separately.Control for oil well, the shortcoming of this conventional process is: need make good use of several hrs usually and just can measure each oil well yield, yet generally each produce oil block all has the oil well that surpasses more than tens, therefore can not finish the measurement of all oil wells within one day;
The another one method is to adopt multi-phase flowmeter to substitute triphase separator.Multi-phase flowmeter must can provide information such as oily flow, discharge, airshed.Optimal multi-phase flowmeter is can be directly and the flow of independent measurement Oil, Water, Gas.Yet unfortunately, up to the present also there is not such multi-phase flowmeter.
Because each main oilfield reserves are all depleted in beginning, must find out more flexible, as to be suitable for a measurement supervisory system.The multi-phase flowmeter that much is used to measure the Oil, Water, Gas potpourri has been arranged in the market, but nearly all multi-phase flowmeter has adopted all the method for radioactive ray to measure.And utilizing the three-phase flow meter of single-stage spin current at present, separating effect still is not ideal enough.
Summary of the invention
Technical assignment of the present utility model is at above weak point, and a kind of multistage cyclone gas-liquid two that uses control convenience, high efficiency, good separating effect three phase metering device that is separated is provided.
The technical scheme that its technical matters that solves the utility model adopts is: this measuring apparatus comprises gas-liquid one-level separation pipeline section, the gas-liquid secondary separates pipeline section, gas-liquid is separated pipeline section for three grades, liquid level control pipeline section and three-phase flow metering controller, the gas-liquid one-level is separated pipeline section, the gas-liquid secondary separates pipeline section, gas-liquid three grades of separation pipeline section and liquid level control pipeline section are connected by pipeline respectively, the gas-liquid one-level separates pipeline section and the three-phase inflow entrance is connected, liquid level control pipeline section connects pressure unit by pipeline, gas meter, fluid level transmitter, mass flowmeter and gas-liquid three-way control valve, gas-liquid three-way control valve and three-phase flow export are connected, pressure unit, gas meter, fluid level transmitter, mass flowmeter and gas-liquid three-way control valve are connected with the three-phase flow metering controller by lead respectively;
Be provided with 45 ℃ of angle inside spins in the gas-liquid one-level separation pipeline section; Be provided with 30 ℃ of angle inside spins in the gas-liquid secondary separation pipeline section; Be provided with 60 ℃ of angle inside spins of power-assisted formula in three grades of separation of gas-liquid pipeline section; 60 ℃ of angle inside spins of power-assisted formula link to each other with motor.
Be provided with universal joint between 60 ℃ of angle inside spins of power-assisted formula and the motor.
45 ℃ of angle inside spins of design in the gas-liquid one-level is separated pipeline section, gas-liquid mixture fluid is because the momentum of self forms eddy flow on internal helical blades, because gas phase is different with the density of liquid phase, the centrifugal force that eddy flow produces is also different, the centrifugal force of gas phase is little, the centrifugal force of liquid phase is big, thereby the free gas phase of big portion is come out from liquid phase separation, and a part of solution gas is evaporated from liquid phase.
The gas phase that the gas-liquid one-level is separated after the pipeline section enters gas-liquid secondary separation pipeline section again, the effect that the gas-liquid secondary separates pipeline section is that the drop in the gas phase is separated as much as possible, therefore separate pipeline section at the gas-liquid secondary and also designed 30 ℃ of angle inside spins, the effect of this inside spin is to hinder liquid phase to move upward, make little drop on inside spin, be gathered into bigger drop, and move downwards along internal helical blades.
The liquid phase that the gas-liquid secondary separates after the pipeline section enters three grades of separation of gas-liquid pipeline section, 60 ℃ of angle inside spins of power-assisted formula have also been designed in three grades of separation of gas-liquid pipeline section, main effect is to increase the residence time of liquid phase in pipeline, thereby more solution gas can be separated from liquid phase.In order to improve gas-liquid separation effect, this inside spin can be rotated by the power that stand-by motor provides in addition.
Liquid phase is through after separating, enter liquid level control pipeline section, again a solution gas is separated from liquid phase, liquid level control pipeline section has been installed a two flange differential pressure fluid level transmitter in position, be used to measure the liquid level in the pipeline section, the three-phase flow metering controller carries out the PID computing according to liquid level signal, according to the aperture of PID operation result control gas-liquid three-way control valve, thereby uses liquid level to remain within certain scope.
Oil-water mixture through after the mass flowmeter metering, enters the gas-liquid three-way control valve mutually, mixes outer defeated with gas phase.
Gas phase enters the gas-liquid three-way control valve through after the gas meter metering, mixes outer defeated with liquid phase.
The multistage cyclone gas-liquid two of the present utility model three phase metering device that is separated is compared with prior art, have reasonable in design, simple in structure, use characteristics such as control convenience, high efficiency, good separating effect.
