Title (EN) DEVICE FOR ELECTROPHORETIC RECTIFICATION OF DRILLING MUD
(FR) DISPOSITIF DE RECTIFICATION ELECTROPHORETIQUE D"UNE BOUE DE FORAGE
Abstract: front page image
(EN)A device for electrophoretic rectification of the drilling mud from a fine-grain solid phase, comprising a reservoir (1) for the drilling mud to be rectified and an electrode (2) sunk into the drilling mud and connected to a direct current source (3) and designed as an endless moving belt (4). The device is provided with a mechanism (5) for cleaning the belt (4) from the solid phase deposited thereon. The endless moving belt (4) is made of an electrically insulating material and is covered on the outer (8) and inner (9) sides with an electroconductive material. The direct current source (3) is connected with its negative pole to the outer side of the belt (4) and with its positive pole to the inner side of the belt (4). The mechanism (5) for cleaning the belt (4) is so mounted as to remove the solid phase from the inner side of the belt (4).
(FR)Un dispositif de rectification electrophoretique d"une boue de forage comportant une phase solide a granulation fine, comprend un reservoir (1) pour la boue de forage a rectifier et une electrode (2) noyee dans la boue de forage et connectee a une source de courant continu (3) et concue sous forme d"une bande sans fin mobile (4). Le dispositif est pourvu d"un mecanisme (5) de nettoyage de la bande (4) de la phase solide deposee sur celle-ci. La bande sans fin mobile (4) est faite avec un materiau electro isolant et elle est recouverte du cote exterieur (8) et du cote interieur (9) avec un materiau electroconducteur. La source a courant continu (3) est connectee par son pole negatif au cote exterieur de la bande (4) et par son pole positif au cote interieur de la bande (4). Le mecanisme (5) de nettoyage de la bande (4) est monte de maniere a enlever la phase solide du cote interieur de la bande (4).
