Experimental Study of Four-electrode Electromagnetic Flowmeter in Oil-water Two-phase Flow in Horizontal Well
In the measurement of oil-water two-phase flow in horizontal wells,the traditional two-electrode electromagnetic flowmeter cannot measure accurate flow data when the flow is between 1～40 m3/d.In order to expand its application,the four-electrode electromagnetic flowmeter has been developed,which is composed of two 90° cross-arranged electromagnetic flowmeters.In a simulation horizontal well with oil-water two-phase flow,a full flow collection method was used to conduct experimental measurement and calibration.The results show that the four-electrode electromagnetic flowmeter solves the problems that the flow data cannot be accurately measured due to the measuring sen-sors are in the oil phase when the flow is between 1～5 m3/d and the water content is over 90% .When the flow is between 5～40 m3/d and the water content is 80%～90%,the four-electrode flowmeter solves the problem of measuring data fluctuation.Compared with the two-e-lectrode electromagnetic flowmeter,the four-electrode electromagnetic flowmeter expands the measurement range,improves the logging suc-cess rate and measurement accuracy.
