Abstract
An oil-water interface measuring device of an oil well crude oil metering tank belongs to a metering device which determines yield by measuring an oil-water interface. The oil-water interface measuring device comprises a signal processor and a measuring barrel communicated with a metering tank. The measuring barrel is equipped with an oil pipe and a water pipe which are communicated with the upper portion and the bottom portion of the metering tank, an oscillator is arranged in the measuring barrel, the lower portion of the oscillator is connected with a detector bar for extending below an oil-water interface in the measuring barrel when measuring, and an output signal of the oscillator is outputted to the signal processor via a lead wire. The oil-water interface measuring device is further provided with a driving mechanism for enabling the detector bar to move upwardly or downwardly. The oil-water interface measuring device has the advantages of high sensitivity and high measuring precision.
Description
Technical field
The utility model relates to apparatus for measuring charge level, thereby especially oil well crude oil water-oil interface is measured the device that calculates the oil well crude output capacity.
Background technology
From the crude oil of oil mining certain water cut is arranged, must pump to earlier in the volume, shape certain " test tank ", carry out the profit gravity separation, then its interphase be measured, converse shared separately volume ratio, thereby the oil yield of this day of oil well is estimated.At present domesticly generally adopt magnetic turnover panel water-oil interface measurement mechanism, but precision is low, error is big, up to the high precision instrument appearance that also not have at present to be suitable for.
The principle of magnetic turnover panel water-oil interface measurement mechanism is: with the ball float of the suitable interior amount magnet steel of density, it floats on the surface, and is in below the crude oil, and the interphase of profit has been represented in the lifting with water surface fluctuation of its position.Row's little turnover panel of magnetic (two sides color difference) upset that the ball float magnet steel promotes vertically to install, the junction of two kinds of colors is exactly the profit boundary.Because viscosity of crude is big, the interval of magnetic turnover panel is big, causes that this instrumental sensitivity is low, measuring accuracy is low.
The utility model content
The purpose of this utility model provides a kind of water-oil interface of following the tracks of and changes, carries out automatically continuous coverage, high-precision oil well crude oil measurement jar water-oil interface measurement mechanism.
This novel purpose is achieved in that an a kind of oil well crude oil measurement jar water-oil interface measurement mechanism, comprises signal processor, also has the measurement tube that is communicated with test tank: measure tube and be provided with oil pipe and the water pipe that is communicated with test tank top and bottom; Oscillator is arranged in the measurement tube and the bottom is connected with a detector bar that is used as below the water-oil interface that stretch into when measuring in the measurement tube, and the output signal of oscillator is transported to described signal processor through lead; Also has the driving mechanism that is used to make the detector bar upstream or downstream.
This is novel to comprise that water-oil interface detector bar, signal removable and that send signal send device and signal processor again.The interface detector bar can move up and down, and when the rod folder moves to the profit interface, sends signal.Measure rod and be contained in and can accurately provide in the gear train of displacement, therefore, the distance that moves from gear train just energy measurement goes out the position of water-oil interface.
This novel ultimate principle is: make the vibration of detector bar generation certain frequency, amplitude is different in the very big former coil neutralization water of viscosity, as long as measure sudden change place of detector bar amplitude, just energy measurement goes out the position of oil water surface.
During use, start driving mechanism and detector bar is slowly inserted (it is suitably slow that speed is wanted) from oil reservoir top down, its amplitude is constant in oil, when passing oil reservoir when touching the water surface, amplitude has the sudden change of a rising, sends signal this moment, write down the distance that gear train moves, can with standard signal (for example 4～20mA) transmission are come out, shown, or with the computing machine communication.
This novel beneficial effect is:
1, solves the viscosity of crude height, influenced the difficult problem of sensor movement.
2, measuring accuracy height is of great importance to improving the daily flow estimation precision.
3, long-range demonstration is exported in measuring process robotization, standard signal, can with computer networking.
This is novel to provide real-time monitoring to create advantage for oil well crude oil yield estimation.
Description of drawings
Fig. 1 is this novel structural representation.
Embodiment
Fig. 1 illustrates, and this novel signal processor that comprises also has the measurement tube 2 that is communicated with test tank 1: measure tube 2 and be provided with oil pipe 8 and the water pipe 7 that is communicated with test tank top and bottom; Oscillator 4 is arranged in the measurement tube and the bottom is connected with a detector bar 3 that is used as below the water-oil interface that stretch into when measuring in the measurement tube, and the output signal of oscillator is transported to described signal processor through lead; Also has the driving mechanism that is used to make detector bar 3 upstream or downstream.Driving mechanism consists of: gear 5 is installed on the step motor shaft, and tooth bar 6 bottoms of meshing with gear 5 are fixed on the oscillator 4.Top, profit separatrix is former oil reservoir 1a in the test tank 1, and the bottom is a water layer.Oil pipe 8 and water pipe 7 should satisfy in the position on the test tank: oil pipe is positioned at more than the profit separatrix at the height on the test tank, the height of water pipe on test tank be positioned at the profit separatrix with next can, preferably, the two is all away from the profit separatrix.Detector bar (metal bar) upstream or downstream driving mechanism can adopt existing alternate manner.Oscillator can adopt TFB-YW (east area of the Liao River, coextensive with eastern and southern Liaoning Province instrucment and meter plant).
