INSTALLATION FOR CONNECTING BALL VALVE TO LOCK OF DRILL INSTRUMENT ON MOUTH OF GUSHER WELL

摘要

Installation for connection of ball valve to lock of drilling instrument on mouth of gusher well has connected to ball valve sub with drives of its translational and rotary motion of cable type. Lock of drill instrument is equipped with guide cone that is fixed at its outer side surface. Diameter of smaller base of inner conical surface of cone is made equal to outer diameter of lock of drill instrument. On face of cone placed at its larger base guide calibrated openings for branches of cable traction are provided, with formation of system for restriction of cable vibration at translational motion of sub and system for suppression of reactive forces at its rotary motion.
