Abstract
A bottom hole assembly supported by coiled tubing has components attached to each other with quick connections that do not require threading to provide the integral connection capable of supporting the BHA's required, torque, tensile and pressure loads. This quick connect feature provides torque transmission capability and does not need rig equipment such as tongs for makeup. Connecting the components is faster and safer particularly when the connections have to be made well above a rig floor. The lower end of the coiled tubing connector can also be provided with a quick connection half to mate with the uppermost tool in the bottom hole assembly.
Claims13
A bottom hole assembly for subterranean use, comprising:
- a coiled tubing string;
- a bottom hole assembly supported by said string;
- at least one connector having a first and a second connectable components to secure at least a portion of said bottom hole assembly to said coiled tubing string, said first component has a mounting end connected to said coiled tubing string and a first connection end on an opposed end thereof, said second component has a mounting end connected to said bottom hole assembly and a second connection end on an opposed end thereof;
- said first and second connection ends are made up such that said first and second connection ends retain each other against axial separation by being brought together with a turn or less of relative rotation between said first and second connectable components such that said bringing together of said connectable components with said turn or less of relative rotation results in rotational locking between meshing splines adjacent said first and second connection ends and externally locking for prevention of axial separation of said connectable components for support of the weight of the bottom hole assembly from the coiled tubing string for running into a subterranean location.
