Abstract

An apparatus having a modular support frame with a top deck. The top deck has a passage therein. A tower is mounted on the top deck. A moveable plate and a track are positioned within the passage. The movable plate is slidingly attached to the track. A support rotary table is disposed within the modular support frame and suspends jointed tubulars. A coiled tubing injector head interface plate is operatively attached to the movable plate, and positioned over the first aperture of the movable plate. The first aperture is positioned over the well in a first position. A rotary table is positioned over the well in a second position. The apparatus is mounted on a transport vehicle in a transport position and moved to a well site. A lifting mechanism lifts the apparatus into an upright position. Well intervention work is conducted with coiled tubing and jointed tubulars.

Claims

1. An apparatus for performing well intervention operations on a well with a coiled tubing unit and jointed tubulars on land, the apparatus comprising:

a modular support frame with a top deck, and wherein said top deck has a passage therein, said modular support frame pivotally mounted on a transport vehicle;

a tower mounted on said top deck;

a movable plate positioned within said passage, said movable plate having a first aperture;

a track formed within the passage, and wherein said movable plate is slidingly attached to said track;

a coiled tubing injector head interface plate operatively attached to the movable plate, and wherein said coiled tubing injector head plate is positioned over said first aperture of said movable plate, and in a first position, said coiled tubing injector head interface plate is positioned over the well;

a lifting mechanism comprising a first end and a second end, wherein the first end is operatively attached to the transport vehicle and the second end is operatively attached to the modular support frame, and wherein the lifting mechanism is capable of moving the modular support frame between a transport position and an upright position for well intervention; and

at least one frame expansion mechanism having a retracted position and an expanded position, wherein the frame expansion mechanism is capable of vertically displacing a portion of the modular support frame when activated by moving from the retracted position to the expanded position.

2. The apparatus of claim 1, further comprising:

a frame locking mechanism having a disengaged position and an engaged position, wherein the frame locking mechanism is capable of locking the frame expansion mechanism in the expanded position when the frame locking mechanism is activated by moving from said disengaged position to said engaged position.

3. The apparatus of claim 1, further comprising:

a tower expansion mechanism, wherein the tower expansion mechanism is capable of vertically displacing a portion of said tower when activated.

4. The apparatus of claim 3, further comprising:

a tower locking mechanism having a disengaged position and an engaged position, wherein the tower locking mechanism is capable of locking the tower expansion mechanism in the expanded position when the tower locking mechanism is activated by moving from said disengaged position to said engaged position.

5. The apparatus of claim 1, wherein said coiled tubing injector head interface plate is laterally movable over said first aperture.
