    Abstract:

    Low-frequency resonant wave-based oil recovery and polymer gel technology have been widely used in production stimulation. To avoid the possible disturbance between the two technologies when combining the two technologies in application, the analysis of the effect of low-frequency vibration on the gel properties is conducted. Based on the viscosity method, the experiment is conducted to evaluate the vibration parameters in the influence on the crosslink of gel. The results show that the low-frequency resonant wave can improve the crosslink with the acceleration from 0.05 G to 0.08 G while it will lead to inhibition in the range of 0.08 G to 0.19 G, and the frequency between 12 Hz and 30 Hz will damage the gelation. Therefore, when combining the two techniques in the oilfield, the frequency and acceleration of vibration should be cautiously chosen in order to avoid the reduction of performance.
