    Abstract
  • By means of the principle that ultrasonic reaction can change the flowing of fluids through porous media and fluid rheological behavoirs,the changes of the curves of core permeability and pressure gradient before and after ultrasonic reaction have been researched.The efficient distance of ultrasonics in the oil layer was discussed in the paper.The study results show that the apparent viscosity of crude oil after ultrasonic reaction decreased greatly,and that the sound rheological behavior of the oil is obvious.The bigger the ultrasonic reaction power is,the stronger the effect on viscosity reduction of crude oil is.The lower the ultrasonic frequency is,the greater the extent of viscosity reduction of crude oil is.The higher the oil viscosity is,the greater the extent of viscosity reduction of crude oil is.
