Embodiment
As shown in Figure 1; Differential pressure type oil-gas-water three-phase metering device of the present invention comprises constant temperature oven, gas-liquid separator, oil-water separator and computer acquisition control processing system; Be connected with check valve, gas meter and differential pressure pick-up 2 on the said gas-liquid separator; Be connected with differential pressure pick-up 1, solenoid valve and balance on the oil-water separator, gas-liquid separator links to each other with oil-water separator.
As shown in Figure 2, gas-liquid separator employing transparent material is processed and is convenient to observe, and a positive umbrella shape device is adorned in the upper end, and the lower end is the device of falling the umbrella shape.When gas and liquid mixture when inlet end gets into separation vessel; Liquid flows to the lower end of separation vessel through umbrella shape device appearance; Gas shows to get into gas meter in the umbrella shape device, make gas-liquid separation more thoroughly gas measure by flowmeter, through the RS232 interface by computer data acquisition.
As shown in Figure 3, oil-water separator adopts ring pipe version, and clear glass is processed, and selects the oil-water separator of different volumes according to the volume of output liquid, and the separation vessel of the different ranges of system configuration supplies experimental selection, 50mL; 80mL; 120mL; 150mL; 200mL; 300mL; Each 5 of 500mL.The left side of separation vessel is output liquid and emulsion end, and the right side is a test lead.Before experiment, must demarcate the pairing volume of promptly different differential pressure value to oil-water separator.
Differential pressure pick-up has two, adopts the U.S. STD924 of Honeywell company product; Range is respectively 0-2KPa; 0-5KPa, precision is 0.1%.Power supply 9-36V, output 0-5V is through the communication of A/D change-over panel and computing machine.Differential pressure value is respectively through the secondary instrument demonstration and through RS-232 communication interface and computing machine communication.Electronic balance adopts German Sai Duodesi import balance, range 1200g; Precision 1%.Data acquisition system (DAS) comprises the instant numerical value of gathering 7 groups of pressure, temperature, balance flow and constant-flux pump pressure etc.
For guaranteeing the reliability of measuring accuracy and control, adopt C168H digital collection control card, thereby realize the digital collection transmission.Software moves under the Windows2000/XP environment, adopts the Delphi programming.The instrument workflow is presented on the interface, can realize man-machine conversation, after operating personnel configure parameter; Just can unmanned; Computing machine can be gathered all pressure, flow automatically, the treated raw data form that generates of the data of computer acquisition, analytical statement and curve map; Generate the database file form simultaneously so that user flexibility is used, as shown in Figure 4.
The important technological parameters of differential pressure type oil-gas-water three-phase metering device of the present invention: constant temperature oven operating room size: 600 * 600 * 1000; Working temperature: 100 ℃ of maximum temperatures; Temperature measurement precision: ± 0.5 ℃; Pressure measurement scope: ⊿ P 10-2KPa ⊿ P 20-5Kpa; Pressure measurement precision: 1 ‰; Gas dosing precision: 2ml; Oil gas metering precision: 0.1g; Check valve controlled pressure: 2-60Mpa; Back pressure control accuracy≤0.02; Supply voltage: AC220V; Dissipated power: 3.5KW.
The workflow of differential pressure type oil-gas-water three-phase metering device of the present invention is following:
Oil, gas, water three-phase get into from separator inlet, because oil, water and emulsion density have nothing in common with each other, oil rises to the oil-water separator upper end, and emulsion rests on the centre of gauge line left side oil and water.The liquid-column height that differential pressure pick-up 1 records in the fine pipeline is a liquid measure, and when surpassing the upper end liquid level, computing machine is opened through D/O input/output board enabled instruction solenoid valve, and water flows on the electronic balance through solenoid valve in the bottom.No matter come in from gas-liquid separator is water or oil, and overflowing through solenoid valve all is water, and promptly metering is water.What differential pressure pick-up 2 measured is that oily increment is an oil mass, the BVO that the ring pipe volume requirement is displaced greater than model.Before doing experiment, to carefully demarcate the volume of ring pipe, promptly at the volume of differing heights.
High precision differential pressure pick-up 2 is measured oil, water termination and accurate position, can record the volume of oil and water in the separation vessel exactly through this potential difference.When separator inlet is come in water; Oil, water termination rise, and computing machine becomes big through the value of the differential pressure pick-up that the A/D change-over panel collects, and computing machine sends instruction and opens motorized valve through the D/O input/output board; Make its oil, water termination get back to initial interface, close motorized valve automatically.At this moment, the value that balance increased is exactly the volume that flows into profit from separator inlet.
