发明名称 INTERNAL TUBING CUTTER
摘要 Implementations of the present invention include an internal tubing cutter including ramp surface(s) and roller that cause cutters to move linearly between retracted and deployed positions. The linear actuation of the cutters can allow for more robust cutting and increased cutting efficiency. Implementations of the present invention also include cutting systems including an internal tubing cutter, and methods of cutting tubular members, such as borehole casings and drill strings, using such drilling systems.
