1.Measurement principle

The liquid from oil well enter into gas-liquid cyclone separation unit of the equipment, the separation unit process the gas-liquid to high efficient multistep separation,then gas freeing.The liquid after separation is output to the lower stage,the liquid phase is more pure through the secondary separation after buffer stability.The separation control unit adjustment and control the liquid phase and gas hydraulic differential.Finally realize gas-liguid two phase stable output,The gas after separation is output from upper gas pipeline of the equipment,the liguid after separation is output from bottom liquid pipeline of equipment.In the end,gas liquid mixed flow out.

2.Main advantages

1. The measurement method is environmentally friendly and conducive to use and promotion;

2. Wide range of applications. It is suitable for multi-phase flow measurement of single well in various complex environments such as land, sea and desert under different working conditions and different medium flow patterns.

3. Adopts the pipeline structure design matching with the process, no pressure device, reliable use;

4. Real-time measurement of liquid, oil, gas, water, temperature, pressure and other production parameters can be achieved;

5. High accuracy of measurement data, obvious comparative advantages;

6. With continuous automatic online measurement and tracking description function;

7. Reliable operation, long service life, easy operation, less maintenance, low operating costs;

8. Real-time collection, calculation and analysis of on-site data can be realized, and liquid, gas, water (oil) measurement curves and various production reports can be generated;

9. Can achieve pressure, temperature, liquid and other data abnormal alarm function;

10. Can realize the remote transmission and transmission of on-site data;

11. Skid mounted structure design, fixed on the drag tool, easy to move, flexible use.

3.Structure

The main body of the device, measuring instruments (mass flow meter, gas flow meter, pressure transmitter, pressure gauge), high pressure connection hose and connecting parts, the device electric thermal temperature control and external insulation system, driving flat car (optional), data acquisition and analysis and processing system, data remote transmission and transmission system (optional).

4.Device classification and selection

Mobile oil and gas continuous metering devices can be divided into hand-pushed mobile devices and pallet mobile devices.
