Abstract
The invention relates to a directional joint for well repairing and bushing removing in an oil field. The directional joint is mainly used for solving the problem that the compatibility between a casing mill tubular column and a borehole is poor and the compatibility between the casing mill tubular column and a casing pipe is poor. The directional joint is characterized in that a ball-shaped hole is formed in the lower end of an upper joint body (1), the upper end of an inner sleeve (3) is provided with a ball head and an inner through hole of the inner sleeve (3) is a tapered hole, the ball head of the inner sleeve (3) is arranged in the ball-shaped hole of the upper joint body (1) and the upper end of a cylindrical body (2) is connected outside the upper joint body (1) through threads. The lower end of the cylindrical body (2) is connected outside the inner sleeve (3) through a spline, the upper end of a lower joint body (4) is connected at the lower end of the inner sleeve (3) through threads, a sealing ring is arranged in an annular groove in the ball-shaped hole of the upper joint body (1) and a sealing ring is arranged in an annular groove in the upper end of the lower joint body (4). The directional joint for well repairing and bushing removing in the oil field has the capacities of improving the compatibility between the casing mill tubular column and the borehole and the compatibility between the casing mill tubular column and the casing pipe.
Description
Technical field
The present invention relates to oil well instrument used, especially oil well gets and applies mechanically steering joint.
Background technology
In oil well field, taking cover technology is thoroughly to repair the overhauling technology that serious cover damages oil-water well.At present, take cover technology and can only be applied to straight well, adopt straight well to get cover technology and carry out directional well cover milling construction, because of milling pipe post rigidity large, compatibility between milling pipe post and sleeve pipe, milling pipe post and well is poor, active force between milling pipe post and the borehole wall and sleeve pipe causes construction not jump seriously, beat and spread sleeve pipe, other stall dish, and even cover mills out new well, cover damage directional well cannot be applied and take the reparation of cover technology.
Summary of the invention
In order to solve the poor problem of compatibility of milling pipe post and well, milling pipe post and sleeve pipe.The invention provides a kind of oil well gets and applies mechanically steering joint.This oil well is got and is applied mechanically steering joint and have the compatibility ability of improving milling pipe post and well, milling pipe post and sleeve pipe.
Technical scheme of the present invention is: this oil well is got and applied mechanically steering joint and comprise top connection, cylindrical shell, inner sleeve and lower contact.There is spherical pore top connection lower end, there is bulb interior set upper side, the inner via hole of inner sleeve is bellmouth, the bulb of inner sleeve is placed in the spherical pore of top connection, cylindrical shell upper end is threaded connection outside top connection, and cylindrical shell lower end is by spline joint outside inner sleeve, and lower contact upper end is threaded connection in inner sleeve lower end, annular groove in top connection spherical pore is built-in with sealing ring, and the annular groove in lower contact upper end is built-in with sealing ring.
The present invention has following beneficial effect: this oil well is got and applied mechanically steering joint owing to adopting top connection lower end to have spherical pore, there is bulb interior set upper side, the inner via hole of inner sleeve is bellmouth, the bulb of inner sleeve is placed in the spherical pore of top connection, cylindrical shell upper end is threaded connection outside top connection, cylindrical shell lower end by spline joint outside inner sleeve, lower contact upper end is threaded connection in inner sleeve lower end, annular groove in top connection spherical pore is built-in with sealing ring, and the annular groove in lower contact upper end is built-in with the structure of sealing ring.Utilize the bulb of inner sleeve and the spherical pore of top connection to coordinate, improve buckling function, increase the flexibility of milling pipe post, make milling pipe post in the situation that of very little support force, change milling pipe post direction, along the milling of directional well well track cover, solve the consistency problem of milling pipe post and well, milling pipe post and sleeve pipe.This oil well is got and is applied mechanically steering joint and have the compatibility ability of improving milling pipe post and well, milling pipe post and sleeve pipe thus.
accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 be in Fig. 1 A-A to sectional drawing.
1-top connection in figure, 2-cylindrical shell, 3-inner sleeve, 4-lower contact.
the specific embodiment:
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, this oil well is got and is applied mechanically steering joint and comprise top connection 1, cylindrical shell 2, inner sleeve 3 and lower contact 4.There is spherical pore top connection 1 lower end, and there is bulb inner sleeve 3 upper ends, and the inner via hole of inner sleeve 3 is bellmouth, and end is provided with chamfering, and while preventing that inner sleeve 3 is crooked, stretch out end, scraped finish sleeve pipe.The bulb of inner sleeve 3 is placed in the spherical pore of top connection 1, and spherical outside surface is sitting in cylindrical shell Internal Spherical Surface, bears longitudinal loading, realizes take the sphere centre of sphere and as flexural center, allowing inner sleeve 3 and lower contact 4 rotate.Cylindrical shell 2 upper ends are threaded connection outside top connection 1, and cylindrical shell 2 lower ends are by spline joint outside inner sleeve 3, and spline is matched in clearance, and inner sleeve 3 is through cylindrical shell 2, and middle part spline and cylindrical shell 2 keyways coincide, and spline plays a part to transmit rotation torque.Lower contact 4 upper ends are threaded connection in inner sleeve 3 lower ends, and the annular groove in top connection 1 spherical pore is built-in with sealing ring, realize the contact surface sealing of top connection 1 and inner sleeve 3.Annular groove in lower contact 4 upper ends is built-in with sealing ring, the joint face of sealing inner sleeve 3 and lower contact 4.Top connection 1 connects top tubing string string, coordinates with inner sleeve 3, realizes crooked break-in.Cylindrical shell 2 connects top connection 1 and inner sleeve 3, and transmitting torque, bears longitudinal loading.Inner sleeve 3 coordinates with top connection 1, utilizes the spline gap of cylindrical shell 2 to realize crooked break-in, and transmitting torque.Lower contact 4 is connected with part 3, transmits lateral torsion, and bottom connects tubing string string.This oil well is got and is applied mechanically steering joint and be applied to directional well and get cover, can realize that milling pipe post and sleeve pipe are compatible, milling pipe post is compatible with well, solves directional well and gets cover and do not jump, break up sleeve pipe and cut off the problems such as sleeve pipe; Be applied to straight well and get cover and receive fish, can increase the flexibility of bottom milling pipe post, strengthen the ability along casing pipe sleeve milling, effectively prevent that straight well from getting cover because milling pipe post rigidity is large, cut off sleeve pipe, lose the problem of well.
