FIELD: construction.
SUBSTANCE: method of displacing a fluid in a wellbore comprises introducing a spacer fluid containing a set-delayed cement composition into the wellbore, so that the spacer fluid displaces one or more prior fluids from the wellbore. Wherein the set-delayed cement composition contains: pumice, hydrated lime, a set retarder, and water.
EFFECT: increasing the efficiency of fluid displacement and well construction.
