Annotation:
The article presents the results of measuring the values of the coefficient of friction, the coefficient of differential sticking of weighted water-based drilling fluids (WBDF) and oil-based drilling fluids (OBDF), containing oil and various lubricant additives. A computer program for calculating the efforts of getting free from sticking is considered.
