SYSTEM FOR MANIPULATING TUBULARS FOR SUBTERRANEAN OPERATIONS

摘要

A system for manipulating tubulars for subterranean operations includes a remote-controlled tubular lift system (RCTLS) having an engagement head configured to engage a proximal end region of a tubular and change the position of the tubular from a substantially horizontal position to a substantially vertical position, wherein in the vertical position a longitudinal axis of the tubular has an angular variation with respect to a predetermined vertical axis of not greater than about 5 degrees.
