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.
