The essence of development. Purpose and scope
In roller bit the new system of grease is used , which prevent intrusion in bearing cavity of mud solution with abrasive materials under big pressure to 60 atm, which is presented by formation processing. The R & D project is designed for efficient utilization in mining.
The main advantages
The service life increases multiply , that does not require frequent upswing and pulling down of drilling rig from great deepness.
The degree of readiness. Protection of intellectual property
Experimental studies were conducted in lab conditions. The design is protected by inventor certificate.
