METHOD OF CONTROLLING TORQUE APPLIED TO A TUBULAR CONNECTION

摘要

Embodiments of the present invention generally relate to a method for
controlling the torque applied to a tubular
connection. In one embodiment, a method of connecting a first threaded tubular
to a second threaded tubular supported by a
spi-der on a drilling rig includes engaging the first threaded tubular with
the second threaded tubular; making up the connection by
rotating the first tubular using a top drive; and controlling unwinding of the
first tubular after the connection is made up.
