Method of cementing in a subterranean formation, method for activating a composition of cement curing time, cement composition on drying time and grouting system

摘要

Summary "method of cementing in a subterranean formation, method for activating a composition of cement curing time, cement composition on drying time and grouting system" are disclosed in this document cement compositions and methods for using up The provisions of the cement curing time in underground formations.A method of cementing in a subterranean formation, can understand to provide a composition of cement curing time which includes water, pumice stone, hydrated lime, and a drying retarder, activate the composition of cement curing time with an activator of drying of Ci Chin,When the activator of drying of cement comprises at least an activator selected from the group consisting of nanosu00edlica, a polyphosphate, and combinations of the same, introduce the composition of cement curing time in an underground formation, and allow the composition of cement dry Gem slow drying in the underground formation. 1 / 1
