Nagorniy, I.I. Denisyuk, Ya.O. Yushytsyna Subbotin Institute of Geophysics, NAS of Ukraine, 63g, B. Khmelnilzky Str., Kiev, 01054, Ukraine, e-mail: vgv_nagornyi@ukr.net Purpose. It is well known that viscosity of oils significantly affects their filtration into oil-gas-bearing strata. In order to reduce viscosity and to increase velocity of forwarding fluids along the fractures, the well- known methods of wave action upon strata are widely used. However, while choosing the frequency range of strata wave processing, the fracture distribution by width is not taken into account, which decreases the effectiveness of the wave effect. In order to reveal new possibilities for choosing the most effective regime of impulse loading of the rock bed, the authors consider the problem of determining velocity and variation of kinematic viscosity during the movement of the liquid in the flat smooth fracture of the rock bed while being wave-loaded by harmonic signal. Design\/methodology\/approach. In solving this problem we used a differential equation which describes the movement of viscous liquid between two parallel planes modulating an endless fracture of arbitrary width. Findings. Here we suggest formulae to determine the average velocity of movement through the fractures and the change in kinematic viscosity of the liquid versus the frequency of harmonic action on the rock bed in the case of different values of the fracture width. It has been found that during the process of action of harmonic signal on the flat smooth fracture filled with viscous liquid, the average stationary velocity of the movement of the liquid reaches its maximal values and kinematic viscosity reaches its minimal values in the case of definite frequency of harmonic action. Practical value\/implications. The results obtained could be useful in elaborating new wave methods of oil-gas-bearing strata processing aimed at increasing effectiveness of hydrocarbons extraction via decreasing fluid viscosity and in\u00adcreasing the velocity of its forwarding to the bottom hole of the producing wells. Keywords: cavity, fluid, frequency, layer, liquid, velocity, viscosity, wave. \u00a0The full text of papers will be available after 01\/04\/2019 References: Afanasenkov I.I., Zhujkov E.F.
