Paper Abstract

With the continual advancement of oil field development, water cut is an extremely important parameter which determines the transmission characteristics of the oil production and provides a scientific basis for oil and gas optimization exploration and increase of reservoir recovery. A new water cut meter based on fiber optic interferometer is proposed, sound pressure signal on the pipe is generated when the acoustic wave is propagated in a mixture of the pipe, the fiber optic sensors wrapped closely around the outside wall of pipe is capable of sensing sound pressure signal, the use of phase-carrier technology aloud sound velocity is solved out through the method of Phase Generated Carrier(PGC)and sound pressure spectrum, then water cut can be solved according to the relationship between sound velocity and water cut.
