| description | The invention relates to an improved method for injecting and transporting small particles in a natural porous medium. The method is characterized in that, in a first step, the porous medium is conditioned by means of an aqueous solution containing a hydrocarbonaceous compound, polymers or surface-active agents, in a second step, a plug of suspended particles is injected in the aqueous medium containing at least one hydrocarbonaceous compound, polymer or surface-active agent and, in a third step, the plug of particles is pushed by an appropriate aqueous medium. The method is particularly useful for implantation of bacteria in a porous medium.
L'invention a pour objet un procédé amélioré d'injection et de transport de particules de petites tailles dans un milieu poreux naturel. Le procédé est caractérisé en ce que, dans une première étape, on conditionne le milieu poreux au moyen d'une solution aqueuse contenant un composé hydrocarboné, de polymères ou tensio-actifs, dans une deuxième étape, on injecte un bouchon de particules mises en suspension dans un milieu aqueux contenant au moins un composé hydrocarboné, polymère ou tensio-actif et dans une troisième étape, on pousse le bouchon de particules par un milieu aqueux convenable. Le procédé est notamment utilisable pour l'implantation de bactéries dans un milieu poreux. |
