Title (EN) DEVICE FOR ELECTROKINETIC SEPARATION OF THE DRILLING MUD INTO LIQUID AND SOLID PHASES
(FR) DISPOSITIF DE SEPARATION ELECTRO CINETIQUE D"UNE BOUE DE FORAGE EN PHASE LIQUIDE ET SOLIDE
Abstract: front page image
(EN)A device for electrokinetic separation of the drilling mud into liquid and solid phases comprises a casing (1) with inlet (2) and outlets (3, 13) for separated phases and electrodes placed inside it, one of them being connected to a negative pole of a direct current source (8) and the other to its positive pole. The electrode connected to the negative pole of the direct current source (8) is executed as a screw (4) provided with a cylindrical (5) and a conical (6) successive sections. The casing (1) serves as an electrode connected to the positive pole of the direct current source (8) and has, correspondingly, a cylindrical (10a, 10b, 10c) and a conical (11) section. The outlet (13) for the solid phase of the drilling mud is situated on the butt-end side of the conical section of the casing (1). The device is provided with a reservoir (14) for collecting the solid phase of the drilling mud connected with the outlet (13) in the casing (1) for the solid phase of the drilling mud.
(FR)Un dispositif de separation electro cinetique d"une boue de forage en phases liquide et solide comprend une enveloppe ou corps (1) ayant une admission (2) et des refoulements (3, 13) pour les phases separees ainsi que des electrodes placees a l"interieur, l"une d"elles etant connectee a un pole negatif d"une source de courant continu (8) et une autre a son pole positif. L"electrode connectee au pole negatif de la source de courant continu (8) se presente comme une vis (4) formee de sections successives cylindriques (5) et coniques (6). Le corps (1) sert d"electrode connectee au pole positif de la source de courant continu (8) et possede, de maniere correspondante, des sections cylindriques (10a, 10b, 10c) et coniques (11). Le refoulement (13) de la phase solide de la boue de forage est situe du cote de l"extremite large de la section conique du corps (1). Le dispositif est pourvu d"un reservoir (14) pour la recuperation de la phase solide de la boue de forage connecte au refoulement (13) du corps (1).
