Abstract

It is proposed to wholistically ensure reliable operation of downhole air hammers. The article describes testing of stresses of air hammer model P150, indicates ways to increasing strength of impacting parts, shows how thermal treatment regimes may influence strength of steel the parts are made of, and present a downhole air hammer design with reduced amount of stress risers in the impacting parts.
