Deflectors for sidetracking in casing strings

TU 3668-002-00147588-2002 (OKP 36 6831) Designed for drilling sidetracks in casing with a diameter of 146 mm and 168 mm without the installation of cement bridges. The diverters are a special wedge device that is lowered into the production string on the pump-compressor or drill pipes to the intended depth, fixing it to the walls of the production string. When lifting a string of drill pipe, the pins are cut off and the diverter remains at a predetermined depth. Cutting the window in the casing produced by the existing technology.
