Abstract
A coiled tubing handler lifts and extends outwardly over wellhead a support platform on which a coiled tubing injector is mounted. The handler collapses into a compact arrangement that allows it and the coiled tubing injector to be transported to a well site on a vehicle or trailer, and then used at the well site to raise, position and support the coiled tubing injector connected to a blow out preventer and riser assembly for connection to a well head. The support platform may be tilted backward and forward, shifted from side-to-side, and raised and lowered on the platform.
Claims13
An apparatus for handling a coiled tubing injector at a well site and positioning it above a wellhead, the apparatus comprising:
- a coiled tubing injector;
- a support platform, on which is mounted the coiled tubing injector;
- a linkage pivotally coupled with a base, the linkage extendable from a stowed position to an operational position in which the support platform is elevated and extended outwardly from the base;
- the linkage comprising a plurality of links, the plurality of links comprising at least a first link and a second link, each of which has a proximal end and a distal end, wherein the proximal end of the first link is pivotally connected with the base, the support platform is pivotally connected to the second link near its distal end, and the proximal end of the second link is coupled through at least one joint to the distal end of the first link wherein the second link is pivotally connected to the distal end of the first link, and wherein the second link is bent between its proximal and distal ends, so that its distal end, where the coiled tubing injector support platform is pivotally connected, is lower to the ground than its proximal end when the linkage is in a collapsed position;
- and
- the linkage further comprising a first extendable member for pivoting the first link with respect to the base between a horizontal position and a vertical position, a second extendable member for pivoting the second link with respect to the first link, and a third extendable member for pivoting the coiled tubing support platform with respect to the second link, whereby extending the first and second extendable members from retracted to extended positions moves the linkage from the collapsed position for transportation to an extended position in which the support platform is raised and moved outwardly from the base.
