Base cement compositions comprising particle-size distribution-adjusting agents, and methods of using such base cement compositions in subterranean operations and surface applications are provided. An example of a method comprises: providing a base cement composition comprising water, a hydraulic cement, a set retarder, and a particle-size distribution-adjusting agent, the base cement composition having a density; adjusting the density of the base cement composition on-the-fly with a density modifying agent to provide a density-adjusted cement; activating the density-adjusted cement composition; placing the density-adjusted cement composition in a subterranean formation; and permitting the density- adjusted cement composition to set in the subterranean formation. Another example of a method comprises: providing a base cement composition comprising water, a hydraulic cement, a set retarder, and a particle-size distribution-adjusting agent, the base cement composition having a density; and adjusting the density of the base cement composition at the job site by variably injecting a density modifier into the base cement composition.

La présente invention concerne des compositions de ciment de base comprenant des agents ajustant la distribution des dimensions de particules et des procédés utilisant de telles compositions de ciment de base dans des opérations souterraines et des utilisations en surface. Un exemple d'un procédé consiste à : proposer une composition de ciment de base comprenant de l'eau, un ciment hydraulique, un retardateur de durcissement et un agent ajustant la distribution des dimensions de particules, la composition de ciment de base ayant une densité ; ajuster la densité de la composition de ciment de base à la volée avec un agent modifiant la densité pour proposer un ciment de densité ajustée ; activer la composition de ciment de densité ajustée ; placer la composition de ciment de densité ajustée dans une formation souterraine ; permettre à la composition de ciment de densité ajustée de durcir dans une formation souterraine. Un autre exemple d'un procédé consiste à : proposer une composition de ciment de base comprenant de l'eau, un ciment hydraulique, un retardateur de durcissement et un agent ajustant la distribution des dimensions de particules, la composition de ciment de base ayant une densité ; et ajuster la densité de la composition de ciment de base sur le site de travail en injectant de manière variable un modificateur de densité dans la composition de ciment de base.
