Abstract

As of today, oil and gas wells are 6,000 m deep or more. In view of this, increased requirements are imposed on the grouting materials used in wells. Grouting fluids must have rheological properties with low values of dynamic shear stress ( τ ) and plastic viscosity ( η ). Reducing the values of τ and η will provide a turbulent flow regime of cementing fluids, which is favourable in terms of complete replacement of the washing fluid with the cementing fluid. In the course of the research, it was found that the Melamine-Formaldehyde Anionic-active Resin superplasticiser is a reagent that has a multifunctional effect on cementing dispersions. This makes it possible to use it in difficult geological and technical conditions for well cementing.
