Technical field
The utility model relates to a kind of gas-liquid two-phase separating controlling measuring apparatus, especially a kind of volume metering device that is used for oil field, oil well individual well oil, gas, aquatic products amount.
Background technology
At present, to ask and produce metering mainly be in order to try to achieve the output of well liquid phase medium to domestic oil field individual well.Usually the device that adopts is that gas-liquid two-phase separator adds measuring instrument, the middle part of gas-liquid two-phase separator is a fluid intake, and fluid enters separation vessel thus, through simple separation, gas phase media is discharged by its upper side outlet, incorporates the outlet manifold into after the metering of screw type vortex shedding flow meter; Liquid phase is then discharged by the device bottom outlet, incorporates the outlet manifold into after the mass flowmeter metering.Since the separation vessel continuous working, and the content of the flow of inlet fluid, gaseous component all is random variation, always contains certain entrained gas in the liquid phase component that the liquid phase outlet is discharged, and the tolerance of carrying secretly also changes.Thereby all kinds of mass flowmeters that caused domestic Oilfield using have had a strong impact on the accuracy of liquid phase component metering in the oil well to the very difficult accurately metering of the fluid of entrained gas in the liquid phase, make troubles to management.In addition, what mass flowmeter adopted usually in the gauging instrument is import instrument, also need be equipped with other utility appliance such as filtrator, costs an arm and a leg, and must clean once every certain operating cycle.Therefore, the existing apparatus metering accuracy is poor, and the equipment cost performance is unreasonable, the maintenance cost height.
Summary of the invention
The purpose of this utility model is for a kind of positive displacement volume metering device is provided, this device is determined the metering of liquid phase medium in the process of oil production in the mode of constant volume, realize the output of oil, gas, water each component in the accurate metering medium, and be not subjected to the influence of oil gas variation and impurity in the oil well.
The purpose of this utility model can realize by following measure:
A kind of positive displacement volume metering device comprises that gas-liquid two-phase separator, gas flow take into account the oil gas variable valve, and gas meter links to each other with the top of gas-liquid two-phase separator with oil gas variable valve serial connection back; The upper side wall of described gas-liquid two-phase separator links to each other with the fluid intake valve sets; It is characterized in that establishing high and low fluid level transmitter in gas-liquid two-phase separator, be connected with pressure unit on the top of this gas-liquid two-phase separator, link to each other with solenoid valve in its bottom, solenoid valve also with density tester links to each other.
Described gas meter, pressure unit, two position transmitter, solenoid valve and density tester all partly link to each other with computer control.
Described two position transmitter is a liquid level sensor.
The utility model has following advantage compared to existing technology:
The utility model adopts volume metering method, promptly determine the two position of measured medium by test simulation, thereby set a volume constant, reach the oil well liquid phase and ask the product purpose by the number of times that fills that calculates measured medium, can directly obtain oil, aquatic products amount by density tester simultaneously, accuracy of measuring height, measuring accuracy can reach more than 2 grades.Simultaneously, can different volume constants be set at any time, realize the controllability and the dirigibility of metering according to the operating mode of different well locations.Control section adopts computer technology, make this device not be subjected to the influence of fluid state, no temperature, pressure, the isoparametric compensation of viscosity, be not subjected to the influence of aspects such as medium impurity, viscosity, gas enclosure, need not filtrator, avoided to greatest extent asking the error of producing metering, have good stable and repeatability, easy and simple to handle, maintenance is little, and is simultaneously reliable for the easy switching of each well.The application of this device has greatly reduced field staff's labour intensity.
