Research on ultra short wave method to measure water content of crude oil

The full measuring range and real-time on-line measurement are new requirements for measuring the water content of the crude oil in oil pipeline with the application of the water flooding technique. The ultra short wave method made best use of the relationship between the ultra short wave transmission property in the crude oil medium including the amplitude attenuation and phase difference and the crude oil physical parameters including the electrical conductivity and permittivity to measure the water content of the crude oil. This method can measure the high and low water content of the crude oil in oil pipeline. The parallel conductor sensor was chosen according to the real workstation and the relationship of the amplitude attenuation, phase difference and the water content. The experimental results prove the ultra short method is feasible. The method has the advantages of the wide measurement range, simple sensor structure and easy installation.
