Influence of Hblock Fine-Grained Material on Selected Parameters of Cement Slurry

Fine-grained materials are used to seal the microstructure and improve mechanical parameters of formed cement sheath. They in slurries designed casing columns at great depths geothermal boreholes thermal conductivity. Such additions shorten setting time transition from value initial final setting. This allows shortening needed bind slurry move on further work. Additionally, it helps eliminate possibility gaseous medium intrusion into structure slurry. The goal work is determine influence Hblock fine-grained material selected research ranging 1% 20% (bwoc (bwoc—by weight cement)), two types most commonly petroleum sector. Then technological fresh hardened were tested. Research rheological parameters, determined models flow curves performed. On basis obtained test results, additive discussed. results allow for then application
