Substantiation of effectiveness of vibroseismic stimulation on deposit

Authors: A.V. Karaketov (Gubkin Russian State University of Oil and Gas, RF, Moscow)

Key words: enhanced oil recovery, vibroseis stimulation on formation, shock supplies of seismic waves.

The article presents a theoretical substantiation of positive effect of vibroseis impact on filtration processes and results of experimental researches on oil displacement in the elastic wavefield. The author has analyzed the physical mechanisms of vibroseis stimulation on the reservoir. Physical dependences for various types of wettability have been obtained. These conditions are in good agreement with experimental results. The author has developed a model of discrete movement clamped “dropping” oil during vibroseis impact on deposit, revealing some aspects oscillatory processes effect on the EOR. It is noted that apart from the effect on capillary-adhesion phenomena elastic waves also affect the rheological properties of oil, on the stress-strain state of the reservoir and on many other physical phenomena, directly and indirectly affecting the oil recovery processes. The results of research are recommended to use in selecting the optimal method of reservoir stimulation, in order to increase oil recovery.
