Description
Technical field
The utility model relates to a kind of flowmeter prover, belongs to oil extraction in oil field injection flow field of measuring techniques.
Background technology
At present, separated-zone water infection oil field all adopts fixedly water nozzle Control section water injection rate, to realize multi-zone flow regulating amount.Well with packer sealing is adopted to testing flow meter downhole flow, to obtain each layer of down-hole injection rate IR.As each layer of injection rate IR and injection allocation amount are not inconsistent,, by changing water nozzle, make each layer of injection rate IR reach the requirement of injection allocation amount.Flow meter calibration is the key that zonal injection well surveying is adjusted, and the true and accurate of test result will directly affect the oil displacement efficiency of injected water.Therefore, when each oil-bearing stratum flooding recovers the oil, guarantee the accuracy of flowmeter under different liquids pressure and environment for use, detect the otherness of flow measurement value, will periodic calibrating flowmeter.At present, the measuring accuracy of existing flowmeter, because liquid body pressure influence can produce calibrated error, cannot meet the technological requirement of zonal injection.
Summary of the invention
The purpose of this utility model is to provide a kind of flowmeter prover, in order to improve the stated accuracy of flowmeter, meets the technical requirement of zonal injection to flowmeter.
Concrete technology contents of the present utility model is as follows:
The frame bottom both sides of this caliberating device are connecting working table and electric winch respectively, slide rail is equipped with on support top, and top is provided with pulley, and wire rope one end connects electric winch, one end is walked around pulley connection and is located at the liquid case on slide rail, and ultrasonic range finder is located on the worktable of slide rail below.Connecting fluid Xiang， lower end, flexible pipe upper end in succession connects front connector, the flowmeter with flow indicator, rear joint, the solenoid valve being located on worktable and is located at the container on electronic scales.Solenoid valve connects controller, and controller is connected with computer and electronic scales simultaneously.
The pressure of this caliberating device energy Accurate Determining fluid to be measured changes, accurately control flow, its measuring accuracy can detect by the difference of the changing value of fluid pressure and the flow of actual displayed and scale survey, and with the reading of the reading proving flowmeter of electronic scales, thereby improve the stated accuracy of flowmeter.The stated accuracy of this caliberating device is high, and working stability is reliable, easy and simple to handle, and calibrated flowmeter can truly reflect water injection rate, can accurately provide continuous data, meets on-the-spot real work needs, ensures the accurate-metering of water filling.
