FIELD: construction.
SUBSTANCE: invention relates to a method of cementing in a subterranean formation comprising: providing a slow-hardening cement composition comprising water, pumice stone, slaked lime, a dispersing agent and a retarder, wherein the retarder comprises a phosphonic acid derivative and dispersing agent contains a dispersing agent based on a polycarboxylate ether; activation of slowly solidifying cement composition; introduction of slowly solidifying cement composition into subterranean formation; and allowing slowly solidifying cement composition to set in a subterranean formation. Invention also relates to a slowly solidifying composition used in said method of cementing. Invention is developed in subclaims of formula of invention.
EFFECT: technical result is slower setting of composition, higher viability thereof.
