Title (EN) WELL COMPLETION SPACER FLUIDS CONTAINING FIBERS AND METHODS
(FR) FLUIDES ESPACEURS DE COMPLETION DE PUITS RENFERMANT DES FIBRES ET PROCEDES ASSOCIES
Abstract:
(EN) Well completion spacer fluids containing flbers and methods of using the spacer fluids are provided. A method of the invention for displacing a first fluid from a well bore with an incompatible second fluid comprises the following steps. A spacer fluid is placed between the first and second fluids to separate the first and second fluids and to remove the first fluid from the walls of the well bore. Thereafter, the first fluid and the spacer fluid are displaced from the well bore with the second fluid. The spacer fluid comprises water, a weighting material, a dispersing agent, a suspending agent and friction reducer and fibers. The spacer fluid containing the components mentioned above is preferably also foamed.
(FR) L'invention concerne des fluides espaceurs de complétion de puits renfermant des fibres et des procédés d'utilisation de ceux-ci. L'invention concerne également un procédé permettant de déplacer un premier fluide d'un puits de forage au moyen d'un second fluide incompatible et comprenant les étapes consistant: à placer un fluide espaceur entre les premier et second fluides, de manière à séparer ceux-ci et à éliminer le premier fluide des parois du puits de forage; puis à déplacer le premier fluide et le fluide espaceur du puits de forage, au moyen du second fluide. Le fluide espaceur comprend de l'eau, un matériau de pondération, un agent de dispersion, un agent de suspension et un réducteur de frottement, ainsi que des fibres. Le fluide espaceur comprenant les composants mentionnés ci-dessus est, de préférence, également moussé.
