Title (EN) EMULSIFIED DRILLING FLUIDS AND METHODS OF MAKING AND USE THEREOF
(FR) FLUIDES DE FORAGE ÉMULSIFIÉS ET LEURS PROCÉDÉS DE FABRICATION ET D'UTILISATION
Abstract:
(EN) Drilling fluids and methods of making and using drilling fluids are provided. The drilling fluid contains an aqueous phase, an oleaginous phase, and at least one surfactant having the formula R-(OC2H4)x-OH, where R is a hydrocarbyl group having from 8 to 20 carbon atoms and x is an integer from 1 to 10. Methods of producing drilling fluids include mixing an aqueous phase, an oleaginous phase, and at least one surfactant, and shearing the mixture. Methods of using drilling fluids to drill subterranean formations include mixing an aqueous phase, an oleaginous phase, and at least one surfactant to produce a mixture, which is sheared to form a drilling fluid, and pumped through a drill string in a drill bit located in a subterranean formation. Rock cuttings are transported from the drill bit to a surface of the subterranean formation and the drilling fluid is circulated in the subterranean formation.
(FR) L'invention concerne des fluides de forage et des procédés de fabrication et d'utilisation de fluides de forage. Le fluide de forage contient une phase aqueuse, une phase oléagineuse et au moins un tensioactif de formule R-(OC2H4)x-OH, où R représente un groupe hydrocarbyle comprenant de 8 à 20 atomes de carbone et x représente un nombre entier de 1 à 10. Les procédés de production de fluides de forage comprennent le mélange d'une phase aqueuse, d'une phase oléagineuse et d'au moins un tensioactif, et le cisaillement du mélange. Les procédés d'utilisation de fluides de forage pour forer des formations souterraines comprennent le mélange d'une phase aqueuse, d'une phase oléagineuse et d'au moins un tensioactif pour produire un mélange, qui est cisaillée pour former un fluide de forage, et pompée à travers un train de tiges de forage dans un trépan situé dans une formation souterraine. Les déblais de forage sont transportés du trépan vers une surface de la formation souterraine et le fluide de forage est mis en circulation dans la formation souterraine.
