The present invention relates to well bore operations, and more particularly, to contained micro-particles, and methods for using such contained micro~particles in cementing operations. An exemplary method of facilitating the use of micro~particles in a well bore fluid comprises the steps of providing contained micro-particles, and adding the contained micro-particles to the well bore fluid. In an exemplary embodiment, the well bore fluids of the present invention comprise encapsulated micro-particles. In another exemplary embodiment, the well bore fluids of the present invention comprise pelletized micro-particles.
La présente invention concerne des opérations de forage de puits, plus particulièrement, des micro-particules contenues, ainsi que des procédés permettant d'utiliser de telles micro-particules contenues dans des opérations de cimentation. Un procédé exemplaire consistant à favoriser l'utilisation de micro-particules dans un fluide de forage de puits comprend les étapes qui consistent à apporter des micro-particules contenues puis à ajouter ces micro-particules contenues au fluide de forage de puits. Dans un mode de réalisation décrit dans cette invention, les fluides de forage de puits contiennent des micro-particules. Dans un autre mode de réalisation décrit dans cette invention, les fluides de forage de puits comprennent des micro-particules sous forme de granulés.
