Title (EN) METHOD AND DEVICE FOR PREPARING A DRILLING MUD
(FR) METHODE ET DISPOSITIF DE PREPARATION D"UNE BOUE DE FORAGE
Abstract: front page image
(EN)A method for preparing drilling mud where the solid and the fluid phases of the drilling mud are mixed in a container (2) until a homogene suspension is obtained, after which the drilling mud is passed, under the pressure, through openings (5 or 6) provided in a piston-like mixing member (3 or 4), the diameter of the openings being bigger than the maximum size of a single particle of the solid phase, but lesser than the diameter of the particles aggregates before obtaining the dispersed drilling mud. A device for implementing the method comprises positive and negative electrodes separated from one another with a semipermeable partition which divides the container (2) into two chambers, one of them being intended for preparation of the drilling mud and another for collecting the products of oxidizing reaction
(FR)Dans une methode de preparation d"une boue de forage la phase solide et la phase liquide de la boue de forage sont melangees dans une enceinte (2) jusqu"a obtenir une suspension homogene, apres quoi la boue de forage passe sous pression au travers d"ouvertures (5 ou 6) amenagees dans un organe de melange en forme de piston (3 ou 4), le diametre des ouvertures etant superieur a la dimension maximum d"une particule de la phase solide, mais inferieur au diametre des agregats particulaires avant d"obtenir la boue de forage dispersee. Un dispositif pour mettre en application la methode comprend une electrode positive et une electrode negative separees l"une de l"autre par une cloison semi-permeable qui divise l"enceinte (2) en deux chambres, l"une d"elles etant destinee a la preparation de la boue de forage et l"autre etant destinee a recuperer les produits des reactions d"oxydation.
