Annotation:
Technological indicators of modern drilling fluids should be strictly regulated: the quality of transportation of cuttings to the surface and cleaning of the wellbore depends on this. However, in practice, the choice of design values of rheological parameters throughout the well section is often incorrect. Such important factors as well design and profile, borehole diameter, casing running depth, geological section, lithology, thermobaric conditions, design planned mechanical speed, etc. are not taken into account. The difference between the optimal values of rheological parameters of the mud for the lower and upper intervals of the well is not taken into account. In The authors of the paper calculate the real rheological parameters of the solution based on its actual movement in the annular space.
