- the periodic pulsation of the pressure of the flow of gas generally excites in it the acoustic vibrations, which are in the last place, cause the cavitational phenomena. Disintegration and stiffening of a cavernous cavity in the flow of a suspended suspension causes an active dispersing phase of a liquid.
- Dispersion of a solid phase of a drilling fluid with a liquid allows grinding of clay particles to a large extent, but for a small number of disks. This is explained by the fact that, by phasing out the water suspension, a part of various sizes is not available. If the suspension is suspended after the active zone of the pulsed device has been reduced for one hour, there is a greater reduction in particle size. However, after each dispersal cycle, there are a few particles that have not reached a predetermined large value.
- the desired set value of the additional phase of the liquid phase should be obtained by changing the voltage

Abstract
Une methode de preparation d'une boue de forage consiste a melanger les phases solide et fluide puis a disperser la phase solide dans la phase fluide jusqu'a former la boue de forage colloidale avec les particules de la phase solide, La dispersion s'effectue en plusieurs etapes. A chaque etape on ajoute une partie de la phase fluide preparee prealablement au melange, le pH de cette phase etant inversement proportionnel au degre de reduction de la dimension des particules de la phase solide a cette etape. Un dispositif de preparation de la boue de forage comprend un electrolyseur a diaphragme (19) dont l'enceinte (22) possede une entree et des sorties (29, 30, 31) pour les parties supplementaires de la phase fluide et, placees dans l'enceinte, une anode (20) et une cathode (21) separees l'une de l'autre par un diaphragme (24) et connectees a une source de courant continu (23). Un dispositif (1) est prevu avec un stator supplementaire (5) et un rotor supplementaire (11) divisant l'enceinte en sections consecutives (6, 7, 8) communiquant entre elles par l'intermediaire d'orifices de deversement (15) amenages dans la region centrale de chaque stator (5) et communiquant egalement avec les sorties correspondantes (29, 30, 31) de l'electrolyseur a diaphragme (19).
