Audited Supplier The oriented sub is a major power deflection tool having a fixed angle (a) deviated from low end
thread of the bent sub to axial line of drill stem, the power drill tool under the application of oriented
sub 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, detecting of the angle
between the big water hole of bit and oriented key of oriented sub shall be done;After run in drill tool,
calculate out the azimuth of big water hole of bit according to the azimuth of oriented key determined at
a single point by drift indicator;Change the big water hole of bit into required azimuth, then lock in rotary
and start pump drilling to cut in; During deflecting, taking a way that deflect while lightly pressing and
crowning of drill to help deflection; After deflected for 2 to 3 meters, drill in 4 to 5 meters with lightly
pressure and rotating slowly; Repeat above operation for several times, when the angle of deviation is
up to the expected requirement deflecting in can be done smoothly by reducing of drill pressure and
increasing of rotating speed.
