CA 2398393

The invention relates to geotechnical processes for extracting mineral products, in particular to methods for effecting productive strata by controlled physical waves and can be used for extracting liquid and gaseous hydrocarbons, water and other liquid and gaseous mineral products from the interior of the earth and also for geophysical studies. The aim of the invention is to increase the transmission efficiency for a vibroseismic signal sent from the source thereof arranged on the earth surface to a productive stratum by increasing the density, specific mass and the rigidity of a ground in the volume of the added mass thereof. The inventive method consists in a wave effect performed on the productive strata with the aid of a seismic vibration source whose radiation platform is arranged on the surface of the ground, and means modifying physical and mechanical properties of the ground in the volume of the added mass thereof.

L'invention relève des processus géotechniques destinés à l'extraction de produits minéraux et notamment des procédés pour traiter des couches productrices par ondes physiques commandées; elle peut s'utiliser dans l'extraction d'hydrocarbures solides et liquides, de l'eau et d'autres produits minéraux solides et liquides du sous-sol ainsi que dans le cadre des recherches géophysiques. L'invention vise à augmenter l'efficacité de transmission du signal vibrosismique depuis sa source, installée à la surface du sol, jusqu'à la couche productrice, et ce grâce à l'augmentation de la densité, de la masse spécifique et de la rigidité du sol dans le volume de la masse ajoutée. Le procédé de l'invention consiste à traiter par ondes la couche productrice, au moyen d'une source de signaux vibrosismiques montée sur une plate-forme de rayonnement à la surface du sol. Selon le procédé de l'invention, on modifie les propriétés physico-mécaniques du sol dans le volume de sa masse ajoutée.
