COMPOSITIONS AND METHODS FOR WELL CEMENTING
The effectiveness of expansive cement systems may be diluted when, during a well cementing operation, commingling takes place between the cement slurry and a spacer fluid, a drilling fluid, or both. Incorporating expansive agents in the spacer fluid or drilling fluid may reduce or negate the loss of...

| description | The effectiveness of expansive cement systems may be diluted when, during a well cementing operation, commingling takes place between the cement slurry and a spacer fluid, a drilling fluid, or both. Incorporating expansive agents in the spacer fluid or drilling fluid may reduce or negate the loss of expansion at the cement slurry/spacer interface or the cement slurry/drilling fluid interface, thereby promoting zonal isolation throughout the cemented interval.
L'efficacité de systèmes de ciment expansif peut être diminuée lorsque, pendant une opération de cimentation de puits, un mélange se produit entre le laitier de ciment et un fluide tampon et/ou un fluide de forage. L'incorporation d'agents expansifs dans le fluide tampon ou le fluide de forage peut réduire ou éliminer la perte d'expansion au niveau de l'interface laitier de ciment/fluide tampon ou de l'interface laitier de ciment/fluide de forage, ce qui favorise l'isolation zonale dans tout l'intervalle cimenté. |
