Water Content Monitoring of Two-Phase Flow in Oil Pipeline Based on Electromagnetic Induction

Oil energy is very important for national development, but with the exploitation of oil resources, the emergence of high water content oil reduces the combustion efficiency. Therefore, timely monitoring of oil moisture content is very important for subsequent oil exploitation. Based on the principle of electromagnetic induction, a sensor array consisting of 8 excitation coils and 12 detection coils is designed to monitor the oil water content in the pipeline. The experiment verifies that the induced voltage is proportional to the moisture content. The experimental results show that the presence of pipeline defects increases the value of induced voltage, but does not change the trend of induced voltage. At the same time, when the number of coils in the sensor array is between 500 and 1000 turns, the sensitivity of the overall monitoring system reaches the best, and too much or too little will affect the result. This is of great significance for improving the efficiency of oil extraction and ensuring energy supply.
