发明名称 SYSTEM WITH A COMPLIANT GUIDE AND METHOD FOR INSERTING A COILED TUBING INTO AN OIL WELL
摘要 The present invention provides a system including a spoolable compliant guide (30), injector (22, 23), and lubricator (40) to obtain vertical access to any oil well (51) and to insert coiled tubing (21) therein to. The spoolable compliant guide provides a substantial distance between the injector and the annular well seal (35) at the lubricator and functions as a crimp or bend resistor for the coiled tubing therein facilitating the imposition of compression forces thereon. This enables the injector to be conveniently positioned remote from the wellhead (50), not necessarily vertically above the wellhead, on the facility with the wellheads or on an entirely separate facility, vehicle or vessel. Wellheads on land, offshore or underwater can all be accessed. Pressurized well fluids are prevented from entering the spoolable compliant guide thus decreasing the risks associated with its damage, failure or emergency disconnection.
