<p>The present invention relates to methods for the exploitation of geological layers using shock waves and vibrations, wherein said invention can be used in down-hole seismic prospecting. The pressure in the liquid filling the well is simultaneously modified in two mutually perpendicular directions that lay on the plane of the well cross section. In a first direction, the pressure is increased on both sides of the intersection point of said directions, while in the second direction the pressure is reduced on both sides of said intersection point. The time for measuring the pressure up to an amplitude value is limited and the pressure modification directions are rotated about the axis of the well while repeating the pressure modification process.</p> |
