摘要： A wellbore tubular handling system and method is provided for operation in holding and lowering tubulars, such as tubing strings, casing strings, pipe strings, and the various components thereof, at a rig site. The handling system utilizes a shock table with a compressible support surface that compressively moves with a selected compression rate in response to the weight of the wellbore tubular string. The shock table preferably has a shock table body mounted below the rig floor and may conveniently replace the rotary table master bushing except for a flange which supports the shock table on the rig floor. A split-sectioned landing spear can be split open to an open position to thereby allow large items such as collars or other string components to pass through the shock table. In a closed position, the landing spear supports, preferably indirectly, an upper collar of the wellbore tubular string to thereby support the weight of the wellbore tubular string and apply the weight to the compressible support surface of the shock table.

摘要： A control line guide and manipulating arm can protect and guide one or more control lines which are desired to be attached and lowered into a wellbore with a tubular string. The control lines may be moved toward a tubular string, can be clamped to the tubular string, and the tubular string and control lines may be lowered into the wellbore. When the elevator reaches a predetermined position, the spider slips are preferably set. To protect the control lines, the control lines are moved in a substantially radial direction outward from the tubular string. The spider slips are closed only after the control lines are retained outward. After another tubular joint is connected to the tubular string and the elevator grips the tubular string, the spider slips are preferably released. For easier attachment, of the control lines to the tubular string, the control lines are moved in a substantially radial direction toward the tubular string. As the tubular string and the control lines are lowered into the wellbore, the manipulator arm may again begin retracting to move the control lines away from the approaching elevator as well as to move the control lines out of the way of the movement of the spider slips. The control line guide, which preferably passes through the spider, protects the control lines from the spider slips by allowing the control lines to remain outside the path of the spider slips as they open and close.

摘要： When the spider slips are open, the control line can be moved toward the pipe string, can be clamped to the pie string and string and line can be lowered into the well. When the pipe connector approaches the spider, the spider slips need to be set. To move the control line into a safe area, it is thrust radially outward from the pipe string. The slips are closed while the line is retained outward.To keep them safe while work proceeds just above the spider an optional trap is closed to retain the control lines until the spider slips are opened. The lines can be manually pulled outward but it is more easily done with a powered thruster. Optional sequencing controls can start with moving the control line away from the pipe, closing the line trap, and closing the spider slips. Reversing the procedure, the sequencing controls open the spider slips, release the line trap, and moves the line toward the pipe.
