Product Description

The oriented bent sub is a major power deflection tool having a fixed angle deviated from the low end thread of the bent sub to the axial line of drill stem. Under the application of oriented bent sub the power drill tool give the bit a constant lateral force to ensure that the bit can cut on the well wall laterally and further drill into a curved well trace.

Operation method

• After the bit and oriented sub are connected and screwed, measuring of the angle between the nozzle of bit and oriented key of oriented bent sub shall be done;

 

• After run in drill tool, calculate out the azimuth of nozzle of bit according to the azimuth of oriented key determined at a single point by drift indicator;

 

• Change the nozzle of the bit into required azimuth, then lock in rotary and start pump drilling to cut in;

 

• During deflecting, using this approach that deflects while lightly pressing and crowning the drill to help deflection;

 

• After deflected for 2 to 3 meters, drill in 4 to 5 meters with light pressure and slow rotation;

 

• Repeat above mentioned operations for several times, when the angle of deviation is up to the expected requirement deflecting in can be done smoothly by reducing drill pressure and increasing rotation speed.
