Abstract
The utility model relates to a well technical field of oil field branch, in particular to branch's well bendable toggle instrument. The device's top connection, the urceolus, outer coupling, the ball seat is from last to connecting in order down, be equipped with directional nipple joint down in the ball seat, directional nipple joint upper portion outer wall designs into convex spherical and articulates under on the ball seat sphere inner wall through this convex spherical, directional nipple joint pass through the convex spherical outer wall can be under ball seat sphere inner wall internal rotation, directional nipple joint outer wall convex spherical upper end is equipped with cam base, be equipped with the piston in the urceolus, the piston lower extreme is equipped with the cam, cam lower extreme slope overlap joint is in directional nipple joint one side, in vogue can the rotation by the actuating cam under the piston, the cam rotates and to drive the rotation of directional nipple joint, the lower clutch is connected to directional nipple joint lower extreme. The utility model discloses a can be upwards crooked by a wide margin in the footpath, the quick accurate reentry multilateral well hole of coiled tubing of being convenient for.
Description
Technical field:
The utility model relates to oil field Multilateral Wells technical field, particularly a kind of Multilateral Wells bendable toggle instrument.
Background technology:
Multilateral Wells construction with coiled tubing connect rotate steerable tool enter branch well hole bottom again time, rotate steerable tool to belong in well and rotate in a circumferential direction, rotational steps is little, the ability entering well is again inadequate, needs research and development a kind ofly can significantly to bend diametrically for this problem, is convenient to the instrument that coiled tubing enters inferior division well.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of Multilateral Wells bendable toggle instrument, the arrangement achieves and can significantly bend diametrically, is convenient to coiled tubing and quick and precisely reentries branch well hole.Overcome existing coiled tubing connection rotation steerable tool rotational steps little, then enter the deficiency of branch well hole difficulty.
Technical solution adopted in the utility model is: a kind of Multilateral Wells bendable toggle instrument, comprises top connection, urceolus and lower contact, top connection, urceolus, outer box cupling, lower ball base connects from top to bottom in turn, directed pipe nipple is provided with in lower ball base, directed pipe nipple external wall of upper portion is designed to convex spherical and is articulated on lower ball base sphere inwall by this convex spherical, directed pipe nipple can be rotated by convex spherical outer wall in lower ball base sphere inwall, directed pipe nipple outer wall convex spherical upper end is provided with cam chair, piston is provided with in urceolus, piston is provided with cam, lower cam end tilts to be overlapped on directed pipe nipple side, can rotate by actuating cam during descent of piston, cam rotates and directed pipe nipple can be driven to rotate, directed pipe nipple lower end connects lower contact.
The beneficial effects of the utility model are: the utility model can significantly bend diametrically, are convenient to coiled tubing and quick and precisely reentry branch well hole.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, a kind of Multilateral Wells bendable toggle instrument, comprises top connection 1, urceolus 2 and lower contact 9, top connection 1, urceolus 2, outer box cupling 5, lower ball base 8 connects from top to bottom in turn, directed pipe nipple 7 is provided with in lower ball base 8, directed pipe nipple 7 external wall of upper portion is designed to convex spherical and is articulated on lower ball base 8 sphere inwall by this convex spherical, directed pipe nipple 7 can be rotated by convex spherical outer wall in lower ball base 8 sphere inwall, directed pipe nipple 7 outer wall convex spherical upper end is provided with cam chair 6, piston 3 is provided with in urceolus 2, piston 3 lower end is provided with cam 4, cam 4 lower end tilts to be overlapped on directed pipe nipple 7 side, can rotate by actuating cam 4 when piston 3 is descending, cam 4 rotates and directed pipe nipple 7 can be driven to rotate, directed pipe nipple 7 lower end connects lower contact 9.
During use, top connection 1 connects coiled tubing, lower contact 9 connects rotation steerable tool, the utility model is lowered into branch well hole place, preset plug in the utility model, plug sets on piston 3, beat hydraulic drive piston 3 descending, piston 3 actuating cam 4 rotates, cam 4 overlaps by inclination angle and directed pipe nipple 7, cam 4 drives directed pipe nipple 7 to rotate, directed pipe nipple 7 leans on spherical rotary in lower ball base 8, the lower contact 9 be connected with directed pipe nipple 7 and bottom fastening means rotate, be beneficial to reentry branch well hole, again look for eye, again can suppress and make piston 3 move downward adjustment angle to look for eye.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
