Abstract

Water cut is one of the key parameters in the process of oil and gas production. In the present study, wepropose a microwave resonant cavity sensor(MRCS) which can work in both TM010 and TM110 modes, andestablished a water cut measurement of vertical upward oil–water two-phase flow in the range of 0-100 %. The response characteristics of the two resonant modes to water cut are analyzed by the coupling simulation offlow field and electromagnetic field using COMSOL finite element simulation software. A flow experimentisconducted with the designed MRCS measurement system. The sensitivity of the two modes resonantfrequency in different water holdup range is compared. The results show that 95 % of the experimental points’ relative errors is less than ± 5 %.It is indicated that the model can predict water hold with high accuracy, which may provide a solution for wellhead water cut measurement of oil field.
