DEVICE FOR ORIENTATION OF FLEXIBLE PIPE IN BRANCH HOLE Russian patent published in 2012 - IPC E21B7/08 

FIELD: mining.

SUBSTANCE: device for orientation of flexible pipe in branch hole is made so that it can be fixed on tubing string and includes hollow housing assembly in which spring-loaded sleeve is arranged with possibility of back-and-forth movement, drive providing the translational movement of spring-loaded sleeve at action of flexible pipe on it, hollow swing spindle in the lower part of which there rigidly fixed is housing with deflection element and longitudinal opening for passage of flexible tube into the well shaft, mechanism providing the conversion of translational sleeve movement to rotational movement of the spindle through discrete angle, as well as it includes the additional sleeve made so that it can centre the flexible pipe and restrict the back movement of spring-loaded sleeve.

EFFECT: higher reliability of the device for orientation of flexible pipe in branch hole and processibillity of operation of such devices.
