Increase of the downhole mud motor operating characteristic when gassy mixtures are used as a working substance

Authors: V.M. Plotnikov (Perm National Research Polytechnical University, RF Perm)

Key words: PDM (downhole screw motor), drilling, pressure drawdown.

The article presents the results of bench testing of PDMs using mixtures and method of their efficiency increase while pressure drawdown drilling of wells. Authors developed and patented a new design of PDM for well drilling using liquid-gas mixture. New PDM design is characterized by torque rating higher than traditional one when.
