DR-106.NGT.5/6.53.М2

Description

PDM DR-106.NGT.5/6.53.M2 is a new universal hydraulic downhole motor used for:

  • drilling of oil and gas wells with 120.6 – 149.2 mm bits,
  • well reconstruction by sidetracking with rock bits, PDC bits, including bicentric ones;
  • well workover operations.

An adjustable bent sub is placed between bearing section and power section. The adjustment range is between 0° and 2° or between 0° and 3°.

Bearing section has axial multi-row rolling bearing and radial hard alloy bearings. Due to a very short shoulder up to the point of axes misalignment (only 1214 mm) drillers can:

  • perform tripping without significant pressing of a bit to internal walls in the production string;
  • perform sidetracking of complex profile where it is required to alternate deviated intervals of more than 5°/10 m built rate and stabilization intervals with rotation of a drill string without the assembly tripping-out to replace the bend angle.
  • minimize risk of leaving the motor parts in the well, as all the threads are screwed applying Loctite glue, and each motor is completed with safety sub.
  • do a large volume of work with one motor (it is especially important for hard-to-reach regions) as the overhaul life reaches approximately 200 hrs.
