Abstract
The utility model relates to a sleeve pipe mobile type universal joint for the completion of a sidetrack horizontal well, which comprises an upper joint, a movable body, a movable supporting seat, sealing rings and a lower joint, wherein the upper joint is connected with the movable body by screw threads, the movable supporting seat is connected with the lower joint by screw threads, a ball body arranged in the movable body is inlaid into a spherical seat arranged in the movable supporting seat, and the sealing rings are not arranged between the ball body and the spherical seat and between the movable supporting seat and the lower joint. The universal joint solves the problems in the prior art that a well pipe post can not be smoothly fallen in place and needs to be forcibly fallen in most cases so that a sleeve pipe, particularly, a sieve pipe is deformed and destroyed in advance. The utility model can be widely used for the well completion of the sidetrack horizontal well.
Description
Technical field:
The utility model relates to the movable universal joint of a kind of sleeve pipe that a kind of sidetrack horizontal well completion is used.
Background technology:
At present Liaohe Oil Field sidetrack horizontal well curvature great majority are all between 12 ° of-16 °/30m, the highest reach 43 °/30m, when completion tubular column down, usually can not put in place down smoothly, in most cases need to cause sleeve pipe by force firmly down, particularly screen casing shifts to an earlier date deformed damaged.We are lowered to difficult problem at the sidetrack horizontal well completion tubular column, have developed the movable universal joint of a kind of sleeve pipe.This universal joint itself has positive and negative 5 ° of bendings, insert the movable universal joint of sleeve pipe of some at the diverse location of completion tubular column, greatly reduce completion tubular column in of the mill resistance of deep camber well section, fundamentally solved completion tubular column and be lowered to difficult problem because of the generation of rigidity intensity.
The utility model content:
The purpose of this utility model is to provide a kind of sleeve pipe movable universal joint, when it has solved the running string that exists in the prior art, usually can not put in place down smoothly, in most cases need by force firmly down, cause sleeve pipe particularly screen casing shift to an earlier date the problem of deformed damaged.
The technical scheme that its technical problem that solves the utility model adopts is: the movable universal joint of a kind of sleeve pipe, form by top connection, movable body, freely movable bearing, sealing ring, lower contact; Top connection and movable body, freely movable bearing and lower contact are screwed connection, and the spheroid in the movable body is embedded in the spheric seat of freely movable bearing, and are equipped with sealing ring between spheroid and ball seat, freely movable bearing and the lower contact; Be subjected to the influence of the horizontal deep camber wellbore trajectory of sidetracking, completion tubular column often is difficult for being lowered to the sidetrack horizontal well completion when being lowered to the big well section of curvature and brings very big inconvenience.This universal joint itself has positive and negative 5 ° of bendings, has reduced the mill resistance that the completion tubular column self rigidity produces, and utilizes the hermetically-sealed construction of spherical piston, not only guarantees bending but also can guarantee sealing.
The beneficial effects of the utility model are, simple in structure, easy making is easy to process; Because this instrument itself has positive and negative 5 ° of bendings, reduced the mill resistance that the completion tubular column self rigidity produces.
Description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure, 1, top connection, 2, movable body, 3, freely movable bearing, 4, sealing ring, 5, lower contact.
The specific embodiment:
In the accompanying drawings, the movable universal joint of a kind of sleeve pipe is made up of top connection 1, movable body 2, freely movable bearing 3, sealing ring 4, lower contact 5.Top connection 1 is screwed connection with movable body 2, freely movable bearing 3 with lower contact 5, and the spheroid in the movable body 2 is embedded in the spheric seat in the freely movable bearing 3, and does not all have sealing ring 4 between spheroid and ball seat, travel(l)ing rest 3 and the lower contact 5.
Claims (1)
1, the movable universal joint of a kind of sleeve pipe, form by top connection (1), movable body (2), freely movable bearing (3), sealing ring (4), lower contact (5), it is characterized in that: top connection (1) is screwed connection with movable body (2), freely movable bearing (3) with lower contact (5), spheroid in the movable body (2) is embedded in the spheric seat in the freely movable bearing (3), and does not all have sealing ring (4) between spheroid and ball seat, travel(l)ing rest (3) and the lower contact (5).
