    The quality and efficiency of sealing the casing is significantly conditioned by proper sealing slurry for the casing as well as entire cementing procedure. The selection of slurry parameters depends on individual conditions and the well to be cemented. Sealing slurries should have certain properties so that they can well perform in the well. Sealing slurries should have a strictly defined time of bonding and be pumpable oper the entire time of cementing procedure. Their technological parameters should be considerably stable in high temperatures and pressure conditions which are present at great depths. Hardened cement stone cannot be corroded, cannot be permeable. It should be adhesive to the drilled rocks and casing. It should also have time-unchangeable strength parameters over the whole period in which the field is exploited through a given well. The results of laboratory experiments on the influence of various concentrations of superplastifier Glenium/R SKY 503 on technological parameters of fresh and bonded sealing slurry based on metallurgical cement CEM III/A 32,5 R are presented in this paper.
