Introduction
Torque Gaurd can automatically adjust the drilling torque in real time and adjust the cutting depth of the bit, so as to realize the "peak and trough" of the fluctuation of bit torque, when PDC bit encounters low service life and low rate of mechanical drilling in hard and soft and hard staggered strata.
Torque Gaurd realizes the cutting depth control of the bit and greatly expands the application scope of the PDC bit.The ability to manage drilling vibrations and stick-slip at deep depths can be used to optimize the use of PDC type drill-bits and mud motors in hot, compacted rock.This tool is similar to Baker Hughes' TerrAdapt drill bit.
Features & Benefits
- Speed up more than 30%;
- Improve mechanical drilling speed and bit footage;
- Reduce stick-slip effect and bit stall;
- Routinely used in HTHP operations;
- Configured for regular vertical as well as deviated drilling;
- Improve measurement accuracy of MWD instrument.
