Title (EN) CHEMICALLY BONDED PHOSPHATE CERAMIC SEALANT FORMULATIONS FOR OIL FIELD APPLICATIONS
(FR) FORMULATIONS D'ETANCHEITE EN CERAMIQUE DE PHOSPHATE A LIANT CHIMIQUE DESTINEES A DES APPLICATIONS DE CHAMPS DE PETROLE
Abstract:
(EN) A sealant for an oil or geothermal well capable of setting within about 3 to about 6 hours at temperatures less than about 250 °F for shallow wells less than about 10,000 feet and deep wells greater than about 10,000 feet having MgO present in the range of from about 9.9 to about 14.5 %, KH2PO4 present in the range of from about 29.7 to about 27.2 %, class C fly ash present in the range of from about 19.8 to about 36.3 %, class F fly ash present in the range of from 19.8 to about 0 %, boric acid or borax present in the range of from about 0.39 to about 1.45 %, and water present in the range of from about 20.3 to about 21.86 % by weight of the sealant. A method of sealing wells is disclosed as are compositions for very high temperature wells is disclosed as is a composition for treating oil field wastes.
(FR) L'invention concerne un matériau d'étanchéité pour puits de pétrole ou puits géothermique pouvant prendre en environ 3 à 6 heures à des températures inférieures à environ 250 °F pour des puits peu profonds inférieurs à environ 10.000 pieds, ainsi que pour des puits profonds supérieurs à environ 10.000 pieds présentant un MgO compris entre environ 9,9 et 14,5 %, un KH2PO4 compris entre environ 29,7 et 27,2 %, de la cendre légère de classe C comprise entre environ 19,8 et 36,3 %, de la cendre légère de classe F comprise entre environ 19,8 et 0 %, de l'acide borique ou du borax dont la teneur est comprise entre environ 0,39 et environ 1,45 %, et de l'eau dont la teneur est comprise entre environ 20,3 et 21,86 % en poids du matériau d'étanchéité. On décrit un procédé d'étanchéification de puits, ainsi que des compositions destinées à des puits de température très élevées. On décrit en outre une composition de traitement de déchets de champs de pétrole.
