Title (EN) CEMENTING COMPOSITIONS AND APPLICATION OF SUCH COMPOSITIONS FOR CEMENTING OIL WELLS OR THE LIKE
(FR) COMPOSITIONS DE CIMENTATION ET APPLICATION DE TELLES COMPOSITIONS DANS LA CIMENTATION DE PUITS DE PETROLE OU SIMILAIRE
Abstract: front page image
(EN)The present invention provides cementing compositions for an oil well or the like, comprising an hydraulic binder, dense particles with a density higher than the density of the hydraulic binder, and reinforcing particles with a density of less than 1.5 g/cm?3¿, preferably less than 1.2 g/cm?3¿, constituted by a flexible material or rubber, of low compressibility and with an average grain size of less than 600 $g(m)m. The compositions of the invention are of particular advantage when cementing zones which are subjected to extreme stresses, such as perforation zones and the junctions of a multi-branch lateral well. They are also highly suitable for producing plugs.
(FR)La présente invention concerne des compositions de cimentation pour un puits de pétrole ou similaire, lesdites compositions renfermant un liant hydraulique, des particules denses dotées d'une densité supérieure à celle du liant hydraulique, et des particules de renforcement dotées d'une densité inférieure à 1,5 g/cm?3¿, de préférence inférieure à 1.2 g/cm?3¿, constituées d'une matière flexible ou de caoutchouc, de faible compressibilité et d'une taille moyenne de grain inférieure à 600 $g(m)m. Les compositions de cette invention présentent un avantage particulier, lorsque des zones de cimentation, telles que des zones de perforation et les intersections d'un puits latéral à plusieurs branches, sont soumises à des contraintes extrêmes. Elles sont également très adaptées à la fabrication de tampons.
