Abstract
Summary
The method of developing oil deposits, based on the injection of water into the reservoir, does not allow the extraction of oil from the bowels completely. This is due to the Saffman-Taylor instability phenomenon. The effect of superimposed nonstationary flow on the stability of the interface between two liquids (water and oil) is theoretically considered in the work. It is shown that there is a critical wave number, beyond which the interface of liquids is stable without the formation of "tongue". To confirm theoretical conclusions, it is necessary to establish and conduct experimental studies in a wide frequency range.
