Abstract: By using the independently developed ultrasonic generator, natural cores with different permeability
are selected to carry out the indoor core displacement experiment under the simulation of the temperature and
pressure of the actual formation, and the effect of ultrasonic action on the removal of reservoir water sensitive
damage has been evaluated during seepage. The results show that for removing reservoir water sensitivity,
ultrasonic frequency has an optimal range, there is a certain compensation relationship between frequency and
power, and there is a certain relationship between the optimal processing time of ultrasound and the physical
properties of the reservoir. The relationship between permeability recovery rate and the physical properties of
reservoirs presents a complex relationship. The results are helpful to understand the mechanism of ultrasonic
water sensitivity removal.
