Title (EN) METHOD OF SEPARATION OF SOLID PHASE IN THE DRILLING MUD
(FR) PROCEDE DE SEPARATION DE LA PHASE SOLIDE D"UNE BOUE DE FORAGE
Abstract: front page image
(EN)A method of separation of the solid phase in the drilling mud consisting in forming with the drilling mud, an adhesive layer (2) on a curved closed surface (3) by way of its partial immersing into the drilling mud and simultaneously rotating it. Then a part of that layer is transferred onto another rotating curved closed surface (5) so located that it contacts with a part of the adhesive layer (2). The linear velocity of the adhesive layer (2) and that of the other rotating curved closed surface (5) are maintained essentially equal at their contact point.
(FR)Un procede de separation de la phase solide dans une boue de forage consiste a former avec la boue de forage une couche adhesive (2) sur une surface fermee incurvee (3) en immergeant celle-ci partiellement dans la boue de forage et en la mettant en rotation simultanement. Ainsi, une partie de cette couche est transferee sur une autre surface fermee incurvee (5) situee de telle sorte qu"elle est en contact avec une partie de la couche adhesive (2). La vitesse lineaire de la couche adhesive (2) et celle de l"autre surface circulaire en rotation (5) sont maintenues sensiblement egales en leur point de contact.
