摘要:
A method and system for installing one or more control lines on a travel joint is disclosed. A control line coil is arranged along a travel joint. An inner mandrel is coupled to an upper bushing and a lower bushing. The control line coil is wrapped along the outer surface of the inner mandrel. The control line coil comprises a first portion located proximate the upper bushing, a second portion located proximate to the lower bushing and a straight length control line extending between the first portion and the second portion. The first distal end of the straight length control line is coupled to the upper bushing and the second distal end of the straight length control line is coupled to the lower bushing
摘要:
A well tool can include an outer housing and a vibratory transmitter disposed in the outer housing. The vibratory transmitter transmits a vibratory signal to an optical line disposed in the outer housing. A well system can include an optical line extending in a wellbore, and at least one well tool secured to the optical line and including a vibratory transmitter which transmits a vibratory signal to the optical line. The optical line conveys the well tool into the wellbore. A method of telemetering data from a well tool to an optical line can include securing the well tool to the optical line without optically connecting the well tool to the optical line, and conveying the well tool in a wellbore on the optical line.

In one embodiment, a line cutter mandrel includes: a tubular mandrel; a pocket disposed along an outer surface of the mandrel and longitudinally coupled to the mandrel; a channel disposed through the pocket for receiving a cable; and a line cutter. The line cutter includes a blade, is operable to engage an outer surface of the cable in a gripping position, is operable to at least substantially sever the cable with the blade in a cutting position, and is operable from the gripping position to the cutting position by relative longitudinal movement between the cable and the pocket.

An expansion joint with one or more communication medium bypass paths is described herein. At least some illustrative embodiments include a first axially flexible cylinder (202), one or more additional axially flexible cylinders (204,206) positioned within the first cylinder (202), and first (210) and second (211) annular members each positioned at a opposite ends of, and each coupled to, the first cylinder (202) and the one or more additional cylinders (204,206) (the first and second annular members each including one or more apertures (212A,212C,214A,214C,220) through each member). All cylinders (202,204,206) concurrently extend and contract in axial length when the first and second annular members (210,211) are respectively moved away from and towards each other. Annular spaces (212B,214B) formed by each of the one or more additional cylinders (202) and an externally adjacent cylinder (204,206), together with corresponding apertures of each of the first and second annular members (210,211), each provides at least one path for at least one communication medium (214D).
摘要:
An apparatus and method for manipulating a control line (4) attached to a tubular string (7) lowered into a wellbore through gripping apparatus (12). The gripping apparatus (12) has a control line passage (14) configured to position the control line (4) away from a set of slips (12b) when the tubular string (7) is held. The apparatus is configured to selectively pull and thrust the control line (4) into and out of the control line passage (14).
摘要:
A method and apparatus are provided for installing control lines and pipe into a well. The pipe-holding spider (12) that is normally mounted on the rig floor is adapted f easy disassembly and reassembly when the pipe slips (60, 62) within the spider are not engaged with the outer surface of the pipe string so that upon disassembly, a control line guide (80) becomes vertically movable. The control line guide is adapted for being controllably elevated to a distance above the rig floor, thereby providing personnel access to a portion of the length of the pipe string below the elevated control line guide and above the rig floor for securing control line to the pipe string using a fastener.
