Title (EN) DEVICE FOR ULTRAFINE DISPERSION OF SOLID PHASE OF THE DRILLING MUD
(FR) DISPOSITIF DE DISPERSION ULTRA FINE DE LA PHASE SOLIDE D"UNE BOUE DE FORAGE
Abstract: front page image
(EN)A device for ultrafine dispersion of the solid phase of the drilling mud comprises an apparatus (1) of a rotary pulsative type the casing (3) of which has an inlet and an outlet for the drilling mud and houses a stator (6) and a rotor (12) with coaxially mounted and alternating cylindrical projections (15, 16) provided with a plurality of radially oriented slots intended for the drilling mud to pass from the inlet to the outlet. The device is provided with a pebble mill (2) the milling chamber of which contains inside freely movable milling bodies (29) and is divided into interconnecting sections (34, 35, 36) with discs (31, 32, 33) fixed on a driving shaft (30). The milling chamber (26) is provided with an inlet for the drilling mud connected with the outlet for the drilling mud in the casing (3) of the apparatus (1) of a rotary pulsative type and with an outlet. The apparatus (1) of a rotary pulsative type has at least one additional stator (7, 8) and at least one additional rotor (13, 14) dividing the casing (3) of the apparatus (1) of a rotary pulsative type into interconnected sections (9, 10, 11). Each section (34, 35, 36) of the milling chamber (26) of the pebble mill (2) is connected through a by-pass pipe (44, 45, 46) with the corresponding section (9, 10, 11) of the apparatus (1) of a rotary pulsative type.
(FR)Un dispositif de dispersion ultra fine de la phase solide d"une boue de forage comprend un appareil (1) du type rotatif a pulsations, dont le corps (3) possede une admission et un refoulement pour la boue de forage et contient a l"interieur un stator (6) et un rotor (12) avec des projections cylindriques coaxiales et alternatives (15, 16) pourvues d"une pluralite de fentes radiales destinees au passage de la boue de forage de l"admission vers le refoulement. Le dispositif est pourvu d"un broyeur de cailloux (2) dont la chambre de broyage contient des organes de broyage mobiles librement (29) et est divise en sections d"interconnexion (34, 35, 36) avec des disques (31, 32, 33) fixes sur un arbre d"entrainement (30). La chambre de broyage (26) est pourvue d"une admission de la boue de forage reliee au refoulement pour refouler la boue de forage dans le corps (3) de l"appareil (1) du type a pulsation rotatif. L"appareil (1) du type a pulsation rotatif possede au moins un stator supplementaire (7, 8) et au moins un rotor supplementaire (13, 14) divisant le corps (3) de l"appareil (1) du type rotatif a pulsations en sections reliees les unes aux autres (9, 10, 11). Chaque section (34, 35, 36) de la chambre de broyage (26) du broyeur de cailloux (2) est reliee par l"intermediaire d"un tube de derivation (44, 45, 46) a la section correspondante (9, 10, 11) de l"appareil (1) du type rotatif a pulsations.
