Annotation:
The article presents the results of modeling a well horizontal section cleaning from cuttings in the ANSYS Fluent software package. The properties of drilling fluids described by means of using the Herschel-Bulkley rheological model were used as fluid parameters. When modeling a two-phase flow, the Euler-Euler model was used. It is assumed that the particles of the solid phase have the same size and spherical shape. As a result of CFD calculations, data were obtained on the effect of the drill string rotation and the rheological properties of the drilling flushing fluid on the concentration of granular particles on the bottom wall of the well.
