VIBRATORY STIMULATION OF FLUID FLOWS IN POROUSMEDIUM OF COAL SEAM
Pavlenko M. V.
pages 455 - 458, full text

The present article describes the results of research related to vibration wave impact on the coal array and the coal seam in particular, which is used to increase the methane recovery in the seam. The known methods of vibrating wave impact on coal array do not always successfully ensure the necessary methane recovery. For experimental research, the effects obtained in laboratory conditions through vibratory simulations of fluid flows in porous medium of coal seam are also considered. A highly recommended method of well treatment is the method of low-frequency effects on the coal seam through wells drilled from the surface. A vibration facility developed with direct participation of the author of this article allows a near-well zone to work in several hydrodynamic regimes without changing the wellhead. Complex research of vibrating wave impact based on a wide range of seam thickness, methane content, pressure and temperature is also needed to account for the impact on the dynamic features of the array. This research allows us to select optimal working parameters of technological facilities using the vibrating wave impact and thereby reduce energy costs and increase the duration of their effectiveness.
