Abstract Aiming at the problems of low automation and large error of existing oil well measurement methods, an oil well liquid phase correlation metering system was designed by using coaxial line phase method water content meter. In order to realize the synchronous measurement of both flow rate and water content, the correlation flowmeter was constructed by the coaxial line phase method water content meter. Moreover, the measurement model was established by cross-correlation method. Through the analysis of the upstream and downstream water content meter signals under different circumstances, it can be seen that there is a correlation between the two signals, to meet the conditions for the use of the correlation flowmeter. Compared with the turbine flowmeter in field tests, the average error of the system was 11.36%. The results proved the feasibility of the system in practical applications.

Key words： multiphase flow measurement;oil well measurement water content meter coaxial line phase method correlation flowmeter cross-correlation algorithm
