Abstract
A kind of oil well takes applies mechanically steering joint.The problem mainly solving milled sleeve and the poor compatibility of well, milled sleeve and sleeve pipe.It is characterized in that: there is spherical pore top connection (1) lower end, there is bulb inner sleeve (3) upper end, the inner via hole of inner sleeve (3) is bellmouth, the bulb of inner sleeve (3) is placed in the spherical pore of top connection (1), cylinder (2) upper end is threadedly attached in top connection (1) outward, cylinder (2) lower end is connected to inner sleeve (3) outward by spline, lower contact (4) upper end is threadedly attached in inner sleeve (3) lower end, annular groove in top connection (1) spherical pore is built-in with sealing ring, annular groove in lower contact (4) upper end is built-in with sealing ring.This oil well takes to be applied mechanically steering joint and has the compatibility ability improving milled sleeve and well, milled sleeve and sleeve pipe.
Description
Technical field
The present invention relates to the instrument used by oil well, especially oil well take and apply mechanically steering joint.
Background technology
In oil well field, taking set technology is thoroughly to repair serious set to damage the overhauling technology of oil-water well.At present, take set technology and can be only applied to straight well, use straight well to take set technology and be oriented well sleeve milling construction, because milled sleeve rigidity is big, poor compatibility between milled sleeve and sleeve pipe, milled sleeve and well, active force between milled sleeve and the borehole wall and sleeve pipe causes construction not jump seriously, beat and spread sleeve pipe, other stall dish, even overlaps and mills out new well, makes set damage directional well cannot apply and take set technology reparation.
Summary of the invention
For the problem solving milled sleeve and the poor compatibility of well, milled sleeve and sleeve pipe.The present invention provides a kind of oil well to take and applies mechanically steering joint.This oil well takes to be applied mechanically steering joint and has the compatibility ability improving milled sleeve and well, milled sleeve and sleeve pipe.
The technical scheme is that this oil well takes to apply mechanically steering joint and include top connection, cylinder, 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, cylinder upper end is threadedly attached in outside top connection, and cylinder lower end is connected to outside inner sleeve by spline, and lower contact upper end is threadedly attached 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.
There is advantages that this oil well takes and apply mechanically steering joint owing to using 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, cylinder upper end is threadedly attached in outside top connection, cylinder lower end is connected to outside inner sleeve by spline, lower contact upper end is threadedly attached 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.The bulb of inner sleeve is utilized to coordinate with the spherical pore of top connection, improve buckling function, increase the flexibility of milled sleeve, make milled sleeve in the case of the least support force, change milled sleeve direction, overlap milling along directional well well track, solve the consistency problem of milled sleeve and well, milled sleeve and sleeve pipe.This oil well takes and applies mechanically steering joint and have the compatibility ability improving milled sleeve and well, milled sleeve and sleeve pipe thus.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention；
Accompanying drawing 2 be in Fig. 1 A-A to profile.
1-top connection in figure, 2-cylinder, 3-inner sleeve, 4-lower contact.
Detailed description of the invention:
The invention will be further described below in conjunction with the accompanying drawings:
As shown in Figure 1, this oil well takes and applies mechanically steering joint and include top connection 1, cylinder 2, inner sleeve 3 and lower contact 4.Top connection 1 lower end has spherical pore, inner sleeve 3 upper end to have bulb, the inner via hole of inner sleeve 3 to be bellmouth, and end is provided with chamfering, and when preventing inner sleeve 3 from bending, end is stretched out, 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 cylinder Internal Spherical Surface, bears longitudinal loading, it is achieved allow inner sleeve 3 and lower contact 4 rotate with the sphere centre of sphere for flexural center.Cylinder 2 upper end is threadedly attached in outside top connection 1, and cylinder 2 lower end is connected to outside inner sleeve 3 by spline, and spline is matched in clearance, and inner sleeve 3 is coincide through cylinder 2, middle part spline with cylinder 2 keyway, and spline plays a part to transmit rotation torque.Lower contact 4 upper end is threadedly attached in inner sleeve 3 lower end, and the annular groove in top connection 1 spherical pore is built-in with sealing ring, it is achieved the contact surface of top connection 1 and inner sleeve 3 seals.Annular groove in lower contact 4 upper end is built-in with sealing ring, seals the joint face of inner sleeve 3 and lower contact 4.Top connection 1 connects top tubing string string, coordinates with inner sleeve 3, it is achieved bending break-in.Cylinder 2 connects top connection 1 and inner sleeve 3, transmits moment of torsion, bears longitudinal loading.Inner sleeve 3 coordinates with top connection 1, utilizes the spline gaps of cylinder 2 to realize bending break-in, and transmits moment of torsion.Lower contact 4 is connected with part 3, transmits lateral torsion, lower connection pipe post string.This oil well takes to be applied mechanically steering joint and is applied to directional well and takes set, can realize that milled sleeve is compatible with sleeve pipe, milled sleeve is compatible with well, solves directional well and takes set and do not jump, break up sleeve pipe and cut off the problems such as sleeve pipe；It is applied to straight well and takes set receipts fish, it is possible to increase the flexibility of bottom milled sleeve, strengthen the ability along casing pipe sleeve milling, effectively prevent straight well from taking set big because of milled sleeve rigidity, cut off sleeve pipe, the problem of loss well.
