    摘要: A fiber optic instrumentation line is introduced down a hydrocarbon (oil) well bore 12 by control line 16 formed by pressure tubing conduit fixed on the outside of intermediate casing 14 and set in cement slurry 21 between casing 14 and surrounding rock 13 and reaching to the hydrocarbon production zone 15. Hollow primary member 18 accepts distal end of control line 16 at the end of casing 14. Secondary member 22 having sealed terminal control line 27 on its outer surface is lowered through primary member 18 to zone 15, automatically angularly aligning and engaging respective top and bottom end couplings 24 and 20, sealing together a respective top and end of terminal control lines 27, 16 forming a continuous, high pressure, fiber optic receiving tube, from well head 10 to well bottom. Alternatively, two lines 16 linked by loop 26 provide a continuous control line returning to the surface.

    摘要: In a well an instrumentation line can be introduced down the well bore by a control line having at least a portion outside of intermediate casing and set in cement slurry between the intermediate casing and the surrounding rock and reaching to a zone of interest. A primary member accepts the distal end of the control line at the end of the intermediate casing. A secondary member has a terminal control line (sealed at its far end) attached on its outer surface. When in place, the secondary member extends into and through the zone of interest. When the secondary member is lowered through the primary member, its top end is lowered onto the bottom end of the primary member. Couplings engage and angularly orientate so that the top of the terminal control line couples to and seals with the distal end of the control line to form a conduit through which a fibre optic instrumentation line can be threaded.
