  • Method and device for measuring visco-elastic fluid parameters
    Patent number: 8396676
    Abstract: The invention relates to measuring visco-elastic fluid parameters, in particular, in the oil production industry, for defining heavy oil parameters during field development. The method involves the excitation of a hollow resonance device oscillations by sending a continuous variable-frequency signal to two transmitting transducers located on the outer surface the said resonance device. Oscillations are recorded by a receiving transducer. Amplitude-vs-frequency response curve is plotted and effective resonance frequency ?r is determined. Thereafter, a cavity of the said resonance device is filled with a medium under examination, and oscillations are excited to obtain associated amplitude-vs-frequency response values. An axially symmetric capacity placed in a thermostabilized chamber is used as the resonance device.
