Title (EN) METHOD AND DEVICE FOR PREPARATION OF DRILLING MUD
(FR) PROCEDE ET DISPOSITIF DE PREPARATION D"UNE BOUE DE FORAGE
Abstract: front page image
(EN)A method of preparation of this drilling mud comprises dosage of a bulk material into a vacuum zone (A), mixing it with a dilution liquid in a capacity (1) and simultaneous dispersion of particles of the solid phase in a dispersion zone (B). The vacuum zone (A) and the dispersion zone (B) are created with adhesive layers (4, 5, 20 and 21) formed by way of rotating curved closed surfaces (2, 3, 16 and 17) partially immersed into the dilution liquid. The vacuum zone (A) is created within the area of the adhesive layers (4, 5, 20 and 21) approaching each other, whereas the dispersion zone (B) is created within the area of divergency of the adhesive layers (4, 5, 20 and 21) from each other. The vacuum degree and the degree of dispersive effect are controlled by adjusting the linear velocity of the said adhesive layers (4, 5, 20 and 21). The method is implemented with a device comprising a mechanism for mixing the bulk material with the dilution liquid, containing at least two driven drums (2 and 3), the adhesive layers (4 and 5) of the dilution liquid being created on the surface of those drums during their rotation. The axes of rotation of the driven drums (2 and 3) are located within the same horizontal plane.
(FR)Un procede de preparation de la boue de forage consiste a doser un materiau en vrac dans une zone de vide (A), a le melanger avec un liquide de dilution dans un reservoir (1) et a disperser simultanement les particules de la phase solide dans une zone de dispersion (B). La zone de vide (A) et la zone de dispersion (B) sont materialisees par des couches adhesives (4, 5, 20 et 21) formees par rotation de surfaces courbes fermees (2, 3, 16 et 17) partiellement immergees dans le liquide de dilution. La zone de vide (A) est creee dans la region des couches adhesives (4, 5, 20 et 21) s"approchant les unes des autres, tandis que la zone de dispersion (B) est creee dans la region de divergence entre des couches adhesives (4, 5, 20 et 21). Le degre de vide et le degre de l"effet de dispersion sont commandes en reglant la vitesse lineaire desdites couches adhesives (4, 5, 20 et 21). Le procede est mis en oeuvre a l"aide d"un dispositif comprenant un mecanisme de melange du materiau en vrac avec le liquide de dilution, comprenant au moins deux cylindres entraines (2 et 3), 1es couches adhesives (4 et 5) du liquide de dilution etant formees sur la surface de ces cylindres pendant leur rotation. Les axes de rotation des cylindres entraines (2 et 3) sont situes dans le meme plan horizontal.
