The purpose of this utility model also can be achieved by the following technical measures:
Described drive unit mainly comprises supporter and cranks arm, this supporter is column or tower-like, the lower end is fixed on the wellhead platform by lower whirligig, the upper end is provided with upper rotary device, described arm of force upper end of cranking arm is connected on the upper rotary device, is provided with dislodging suspension ring and righting rod tube mechanism on the described transverse arm of cranking arm.
The height of described supporter is slightly larger than supporter apart from the vertical distance of well head, described transverse arm of cranking arm perpendicular to the rotating end of support column axis stretch to well head with by swing pipe post line, crank arm stretch to well head with by the mid point of swing pipe post line one end on above-mentioned line, when rotation of cranking arm crank arm transverse arm mid point trajectory diagram well head with by the line of swing pipe post on.
The utility model be installed in well head with by the side of centralising tube line, mechanical arm forwards " line " upper guiding righting to during work, mechanical arm leaves " line " wait instruction that retours after " centering ".Be applicable to righting and the work of dislodging suspension ring of wellhead column in the do mechanization operation, guarantee that tubing string removes smoothly.Have righting distance large, abdicate enough spaces, invest the characteristics such as little, easy to operate for traveling system.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1-dislodging suspension ring and righting rod tube mechanism, 2-cranks arm, 3-support column, 4-upper rotary device, whirligig under the 5-, 6-wellhead platform.
The specific embodiment:
The lower end of rod tube righting guiding dislodging hoisting ring device support column 3 is fixed on the wellhead platform 6 by lower whirligig 5, cranks arm 2 to be installed on the support column 3 by upper rotary device 4, and dislodging suspension ring and righting rod tube mechanism 1 are installed in cranks arm on 2.Can replace the people to finish guiding righting rod tube at wellhead platform, arrive well head top and centering screw thread from the well site or make rod tube arrive the well site from well head, can replace the people to finish the work of dislodging suspension ring.
Using method of the present utility model, the extension suspension ring operation when the extension suspension ring operation when its step comprises lower tubular column and the rod tube righting operation when plucking suspension ring operation, lower tubular column, lift pipe string and the rod tube righting operation when plucking suspension ring operation, lift pipe string;
Wherein, extension suspension ring operation during lower tubular column and pluck the suspension ring operation and be, when needing to hang suspension ring, dislodging suspension ring and righting rod tube mechanism be placed in advance well head with by swing pipe post line on the closest approach of distance wellhead platform face, when being stretched into the elevator opening of traveling system suspention from the well site by the swing pipe post, well site rod tube lifting opens and closes elevator apparatus and closes the elevator opening, after tubing string is sling by elevator, dislodging suspension ring and righting rod tube mechanism are under the drive of cranking arm, meet to by the lower end of swing pipe post, go righting guiding tubing string and well head centering, finish rod tube righting operation, after detaining on the tubing string, traveling system upper lifting pipe post, dislodging suspension ring and righting rod tube mechanism rotate around support column under the drive of cranking arm, for traveling system is abdicated working space, the elevator transporter is removed elevator, for the elevator that traveling system hangs is abdicated the space, when the elevator of traveling system suspension does not arrive wellhead platform, another elevator shipping unit is put in the well head top, waits for and accepts the heavy elevator that traveling system hangs.Then, when heavy elevator is put on the well head, the well head suspension ring are unsnaped by dislodging suspension ring and righting rod tube mechanism, namely finish and pluck the suspension ring operation, traveling system is up, and the elevator transporter is delivered to the well head top with empty elevator, transfers traveling system, dislodging suspension ring and righting rod tube mechanism hang over empty elevator on the suspension ring, namely finish and hang the suspension ring operation;
Wherein, extension suspension ring operation during lift pipe string, pluck the suspension ring operation and rod tube righting operation is, rod tube righting operation during described lift pipe string is, traveling system upper lifting pipe post, when carrying to elevator transporter top on next endowel box cupling, the elevator transporter moves to well head with elevator, close elevator, traveling system is transferred tubing string, the string collar seat is hung tubing string in the well on elevator, unload the top tubing string, dislodging suspension ring and righting rod tube mechanism are cranked arm to drive gets back to the well head axis, the guiding tubing string is put on the slide rail of well site lifting keying elevator apparatus, when the weight that promotes tubing string all is placed on the slide rail, well site rod tube lifting opens and closes elevator apparatus elevator is opened, promote tubing string and be sent to the well site, traveling system is descending, empty elevator is placed on the elevator transporter of waiting for the well head top, at this moment, dislodging suspension ring and righting rod tube mechanism are cranked arm to drive gets back to the well head axis, suspension ring are unsnaped by dislodging suspension ring and righting rod tube mechanism, namely finish and pluck the suspension ring operation, the elevator transporter shifts out well head with elevator, traveling system continues descending, dislodging suspension ring and righting rod tube mechanism hang over suspension ring in the suspension ring opening of heavy elevator of tubing string in the suspention well, namely finish and hang the suspension ring operation, on carry traveling system and continue to trip out the interior tubing string of well.
