Measurement of water holdup in oil-in-water emulsions in wellbores using microwave resonance sensor

In order to adapt to the reality that a large number of wells are dispersed in the oilfield and the measured output fluid inside the wells contains less gas, and at the same time accurately obtain the water holdup parameter that affects the key factors of oil production. The numerical simulation model of the permanently dynamic and static water holdup measuring device is established by using the finite element, and its structural parameters, electrical characteristics, sensitivity distribution, and response characteristics are analyzed and optimally designed, to determine the optimal structure and the best performance indexes of the measuring device. On this basis, a permanently dynamic and static water holdup measuring device was developed, and experimental research was carried out on the built measuring platform. It was verified that the measuring devices showed good linearity between measurement results and standard values. The experimental results are analyzed for multi-phase flow conditions such as the water flow rate range of 5-70m3/d and water holdup range of 50%-95%, the measurement error of the phase holdup is within 5%. Both practice and simulation prove that measuring device has good performance.
