摘要： A tube turning tool allows laterals to be drilled and completed without the need for articulated bending tools, underreaming, high fluid pressure, or a separate running of completion tools. The turning tool uses a rigid bent pipe section capable of being run downhole within many standard diameter well tubulars, supported in a desired position, and bending coil tubing at an ultra short radius of curvature as it is being run into the wellbore so that it can jet drill a lateral. After jet drilling a lateral, the lateral can also be completed using the coil tubing, e.g., gravel packed by pumping a slurry through the coil tubing while withdrawing the tubing from the lateral.
