MULTIPHASE FLOW RATE MEASUREMENT USING A NOVEL CONDUCTANCE VENTURI METER EXPERIMENTAL AND THEORETICAL STUDY IN DIFFERENT FLOW REGIMES

Abstract:

Multiphase flow rate measurement is a challenging task in oil and gas production industries. In this study, a novel conductance venturi meter is proposed for multiphase flow rate measurement. The meter is based on the principle of conductance measurement, and it is designed to measure the flow rate of gas, oil, and water in a pipeline. The experimental study is conducted to evaluate the performance of the meter in different flow regimes, including stratified, slug, and annular flow. Theoretical analysis is also performed to validate the experimental results and to investigate the effect of different parameters on the meter performance.

The results show that the conductance venturi meter can accurately measure the flow rate of gas, oil, and water in different flow regimes. The meter has a high sensitivity to changes in the flow rate, and it can detect small changes in the flow rate with high accuracy. The experimental results are in good agreement with the theoretical analysis, and the meter performance is found to be independent of the flow regime.

The study also investigates the effect of different parameters on the meter performance, such as the pipe diameter, the venturi throat diameter, and the fluid properties. The results show that the meter performance is affected by these parameters, and they should be considered in the meter design and calibration.

In conclusion, the conductance venturi meter is a promising technology for multiphase flow rate measurement in oil and gas production industries. The meter has a high accuracy, sensitivity, and robustness, and it can be used in different flow regimes and fluid properties. The results of this study can be useful for the development of new multiphase flow meters and for the improvement of existing ones
