Manipulatable spider components adapted for cooperation with a vertically reciprocating control line guide
View Patent ↗A method and apparatus are provided for installing control lines and pipe into a well. The pipe-holding spider that is normally mounted on the rig floor is adapted for easy disassembly and reassembly when the pipe slips within the spider are not engaged with the outer surface of the pipe string so that upon disassembly, a control line guide 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.
1. An apparatus for installing a control line and a pipe string in a well, comprising:
a spider having a tapered bowl with a radial slot and adapted for repetitive removal and reinsertion of slips from and into the tapered bowl;
a control line guide adapted for vertical reciprocation of at least a portion of the control line guide through the slot of the tapered bowl from a first position with at least a portion of the control line guide beneath the tapered bowl to a second position with at least a portion of the control line guide above the tapered bowl.
2. The apparatus of claim 1 wherein the control line guide is adapted to be reciprocated only when a pipe string is not supported by the spider.
3. The apparatus of claim 1 further comprising a powered jack for vertically raising and lowering the control line guide.
4. The apparatus of claim 3 wherein the powered jack also raises and lowers at least one of the slips from and toward its engaged position in the tapered bowl.
5. The apparatus of claim 3 wherein the powered jack is hydraulic.
6. An apparatus for securing a control line to a pipe string being run into a well, comprising:
a spider having a tapered bowl for receiving slips for engaging and supporting a pipe string, and
a control line guide adapted for reciprocation through a slot in the tapered bowl when the slips are removed from the path of the control line guide.
7. The apparatus of claim 6 further comprising a gate on the spider having an open position for receiving removal of a pipe string from the spider and a closed position for receiving the slips to engage and support the pipe string.
8. A method of installing a control line to a pipe string in a well bore using a spider having slips and a tapered bowl for receiving the slips, comprising:
supporting the pipe string using a draw works;
moving at least one of the spider slips or the tapered bowl away from the pipe string;
raising a control line guide adjacent to a portion of the pipe string to extend the control line along the portion of the pipe string above the spider;
securing the control line to the pipe string above the spider and below the raised control line guide;
lowering the pipe string and the secured portion of the control line;
lowering the control line guide to a position with at least a portion of the control line guide being below the top of the spider when the spider is in its position aligned with the well;
restoring the at least one of the spider slips or the tapered bowl to its position around the pipe string; and
engaging and supporting the pipe string with the spider slips.
9. The method of claim 8 further comprising the steps of moving the tapered bowl away from the pipe string and raising the slips along at least a portion of the pipe string.
10. The method of claim 9 further comprising the step of raising the slips along at least a portion of the pipe string using a powered jack.
11. The method of claim 8 further comprising the step of raising the control line guide adjacent to at least a portion of the pipe string using a powered jack.
12. The method of claim 11 further comprising the step of raising the control line guide using a scissor-jack.
13. The method of claim 11 further comprising the step of raising the control line guide using a hydraulic jack.
14. The method of claim 11 further comprising the step of raising the control line guide using a screw jack.
15. The method of claim 8 further comprising the steps of moving the tapered bowl away from a portion of the pipe string to a removed position and moving the tapered bowl toward the portion of the pipe string to an engaged position using a platform.
16. An apparatus to install a control line and a pipe string in a well, comprising:
a spider having a tapered bowl with a radial slot therein; and
a control line guide vertically movable relative to the tapered bowl so that at least a portion of the control line guide passes through the slot when raised from a first position, with at least a portion of the control line guide beneath the tapered bowl, to a second position, with the at least a portion of the control line guide above the tapered bowl.
17. The apparatus of claim 16 further comprising an actuator to move the control line guide between the first position and the second position.
18. The apparatus of claim 17 wherein the actuator is selected from the group consisting of a screw jack, a scissor jack, a hydraulic jack and a pneumatic jack.
