Abstract

"COMPOSIçãO DE CIMENTAçãO E SUA APLICAçãO PARA CIMENTAR POçOS PETROLìFEROS OU SIMILARES". Composição de cimentação para um poço petrolífero ou similar com porosidade de menos do que 50%, e com uma fase sólida constituída de 35% até 65% (em volume) de microesferas ocas, de 20% até 45% de cimento Portland Classe G, e de 5% até 25% de micro-cimento Portland Classe G. A invenção é usada para cimentar tubos condutores em zonas árticas ou em furos em águas profundas."CEMENTATION COMPOSITION AND ITS APPLICATION TO CEMENT PETROLEUM OR SIMILAR WELLS". Cementation composition for an oil well or similar with a porosity of less than 50%, and with a solid phase consisting of 35% to 65% (by volume) of hollow microspheres, from 20% to 45% of Portland G Class cement, and from 5% to 25% of Portland Class G micro-cement. The invention is used to cement conductive tubes in arctic zones or in deep water holes.
