Single well metering multiphase flow meter

STRUCTURE COMPOSITION AND  MEASUREMENT PRINCIPLE

1.Structure composition

Gas liquid cyclone separator, gas-liquid separation controller, measuring instrument, data acquisition and processing system, data remote transmission system, remote data access and distribution

system (optional).

2.Measurement principle

Liquid from oil well realizes the efficient separation of gas liquid two phase flow through gas-liquid cyclone separator. The gas liquid two-phase liquid level and pressure difference are controlled by the gas-liquid separation controller to ensure that the cyclone separator of gas and liquid separation's effect reaches the best. The gas and liquid after separation realizes accurate measurement of liquid volume, water cut and air volume through mass flow meter and vortex gas flow meter respectively. Field pressure data can be measured by pressure transmitter.

MAIN ADVANTAGES AND TECHNICAL CHARACTERISTICS

1.The non-radioactive measuring method is more environmentally friendly, safe and reliable.

2. It has a wide range of application. t can be applied to multiphase flow measurement of single well and total oil field under different working conditions and different media flow conditions in various complex environments, such as land, sea and desert.

3. The design of pipeline structure matches the process, with no pressure devices, used more safely

4.It can be used to measure liquid, oil, gas, water, temperature and pressure.

5. The accuracy and repeatability of measurement data are obvious.

6. With the function of 24 hours' continuous online measurement, it can generate liquid, gas, water (oil) measurement curve and various production reports according to customers' requirements.

7.With the function of abnormal data alarming of pressure, temperature and liquid.

8. Simple manipulation, reliable operation, long service life, less repair and maintenance.

9. It has functions of real-time data acquisition, remote transmission and distribution. It can conve-niently, timely, comprehensively and completely monitor the work site, providing the basis for scientific decision-making.

10. Unique skid mounted design is more convenient to use and move.
