   The effectiveness with which a rotary drilling rig performs affects on economical profitability of whole oil and gas production process. The nature of the bottom-hole cleaning for rotary drilling is still not sufficiently elucidated. To achieve good bottom-hole cleaning an optimal drilling mud circulation program (hydraulics program) is required. Discussion presented in this paper is focused on bit hydraulic horsepower and impact force criterions. A mathematical model of drilling hydraulics and its computer application for use in fieid practice is presented. Selected data are included in tabular form and some hard copy protocols from computer are attached.
