Summary:The present invention relates to improved well fluids that include hollow particles, and to methods of using such irnproved well fluids in subterranean cementing operations. The present invention provides methods of cementing, methods of reducing annidar pressure, and well fluid compositions. While the compositions and methods of the present invention are useful in a variety of subterranean applications, they may be particularly useful in deepwater offshore cementing operations. La présente invention se rapporte à des fluides de forage perfectionnés comprenant des particules creuses, ainsi qu'à des procédés de mise en oeuvre de fluides de forage perfectionnés de ce type dans les opérations de cimentation souterraine. La présente invention propose des procédés de cimentation, des procédés de réduction de la pression annulaire, et des compositions de fluide de forage. Bien que les compositions et procédés selon la présente invention sont utilisables dans différentes applications souterraines, ils sont tout particulièrement utiles dans les opérations de cimentation en eau profonde.
