The invention relates to a method of drilling a bore hole into a stratum, wherein via the drill hole drilling fluid is introduced and fed to the drill head. In order to avoid dilution or leak-off of the drilling fluid the same is in accordance with the invention a magnetorheological drill~ing fluid, and when an undesirable pressure difference occurs between i) the drilling fluid at the height of the drill head and ii) a fluid present in the stratum surrounding the drill head, a magnetic field is applied. The inventions also provide a permanent solution.
L'invention porte sur un procédé de forage d'un trou de forage dans une strate, le fluide de forage étant introduit à travers le trou de forage et conduit vers la tête de forage. Un champ magnétique est appliqué afin d'éviter la dilution ou la fuite du fluide de forage, ce dernier étant un fluide de forage magnétorhéologique, et lorsqu'une différence de pression indésirable se produit entre i) le fluide de forage à la hauteur de la tête de forage et ii) un fluide présent dans la strate entourant la tête de forage. L'invention porte également une solution permanente.
