Further, displacement to axial can be produced between described wear-resistant sleeve and described inner sleeve.
Further, described inner sleeve is long semicircle along the tangent plane of adapter body axis, adapter body is provided with the groove corresponding with described inner sleeve.
Further, described inner sleeve is fixedly connected in described adapter body by screw.
Further, the forward and backward two ends of described adapter body are respectively arranged with the screw thread be connected with drilling tool.
Further, the material of described inner sleeve is polyether-ether-ketone resin.
Further, the external surface of described wear-resistant sleeve is milled with helicla flute, in order to reduce the contact area with sleeve pipe.
Further, described wear-resistant sleeve inner surface chromium plating.
Operating principle: in drilling process, wear-resistant sleeve on antifriction joint and inner sleeve can relatively rotate, and the external diameter of wear-resistant sleeve is larger than drill pipe tool joint and drilling rod external diameter, therefore at work, tool-joint and drilling rod can not contact with sleeve pipe, and wear-resistant sleeve is by elder generation and casing-contact.Wear-resistant sleeve contacts with casing inner diameter and produces friction and be in non-rotating state, and wear-resisting, so just can reduce casing wear, also reduce drilling rod and drill pipe tool joint loss simultaneously.
The beneficial effects of the utility model are:
(1) the utility model protect joint with original drilling rod compared with there is structure advanced person, safe and reliable, righting antifriction effect is remarkable.

(3) anti-friction ring and inner sleeve are by polyether-ether-ketone
(pEEK) resin is made, and has good abrasion resistance.
(4) wear-resistant sleeve external surface is milled with helicla flute, and reduce the contact area with sleeve pipe, frictional force is less, antifriction and subtract and turn round better effects if, substantially prolongs wear-resistant sleeve and application life of antifriction joint in application life.
(5) wear-resistant sleeve bore area chromium plating processing, makes wear-resistant sleeve more wear-resisting, substantially prolongs wear-resistant sleeve and application life of antifriction joint in application life.
(6) produce very little displacement to axial and rotation between wear-resistant sleeve and inner sleeve, this reduces the vibrations that shock produces, play the effect of damping.
(7) wear-resistant sleeve is positioned in the middle of joint body, has certain interval, allows wear-resistant sleeve freely to rotate, better can reduce the wearing and tearing between sleeve pipe.
(8) wear-resistant sleeve is detachable and changes outside dimension, can in different sleeve pipes, and select different wear-resistant sleeves, limitation is little, widely applicable.
(9) antifriction jiont treatment, convenient disassembly.
(10) antifriction joint alleviates the torque load of drill string, adds drilling ability, is conducive to the pressure of the drill and moment of torsion transmission, improves rate of penetration, accelerate bit speed, saved the activity duration, for cost has been saved in drilling well.
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Accompanying drawing illustrates: 1. adapter body; 2. locating part; 3. wearing ring; 4. inner sleeve; 5. wear-resistant sleeve; 6. screw.
Detailed description of the invention
A kind of abrasion reducing joint, comprise adapter body 1, adapter body 1 external surface is fixedly installed inner sleeve 4, and the outer cover of inner sleeve 4 has wear-resistant sleeve 5, and wear-resistant sleeve 5 can the axis of solderless wrapped connection head main body 1 rotate relative to inner sleeve 4; Adapter body 1 is provided with locating part 2 pairs of wear-resistant sleeves 5 and carries out axial limiting.
Locating part 2 is fixed cover, and fixed cover inwall is provided with internal thread, is threaded connection between fixed cover and adapter body 1; Fixed cover and the close one end of wear-resistant sleeve 5 are provided with wearing ring 3.The material of wearing ring 3 is polyether-ether-ketone resin.Polyether-ether-ketone
(pEEK) resin is made, it is a kind of special engineering plastics of excellent performance, have more significant advantages compared with other special engineering plastics, resistance to positive high temperature 260 degree, mechanical performance are excellent, self lubricity is good, chemicals-resistant burn into is fire-retardant, peel resistance, abrasion resistance are good.
Displacement to axial can be produced between wear-resistant sleeve 5 and described inner sleeve 4.
Inner sleeve 4 is long semicircle (up and down each long semicircle) along the tangent plane of adapter body 1 axis, and adapter body 1 is provided with the groove corresponding with described inner sleeve.Inner sleeve 4 is fixedly connected in adapter body 1 by screw 6.Inner sleeve and adapter body can be fixed by flush end trip bolt the plane that long semicircle inner sleeve contacts with adapter body.
The forward and backward two ends of adapter body 1 are respectively arranged with the screw thread be connected with drilling tool.Front end is provided with external screw thread, and rear end is provided with internal thread.
The material of inner sleeve 4 is polyether-ether-ketone resin.
The external surface of wear-resistant sleeve 5 is milled with helicla flute, and in order to reduce and the contact area of sleeve pipe, frictional force is less, antifriction and subtract and turn round better effects if, substantially prolongs wear-resistant sleeve and application life of antifriction joint in application life.
The chromium plating of wear-resistant sleeve 5 inner surface, makes wear-resistant sleeve more wear-resisting, substantially prolongs the application life of wear-resistant sleeve and antifriction joint.
Because the external diameter of wear-resistant sleeve is larger than drill pipe tool joint and drilling rod external diameter, so tool-joint and drilling rod can not contact with sleeve pipe, wear-resistant sleeve is by elder generation and casing-contact.When antifriction joint and casing-contact, frictional resistance between wear-resistant sleeve with sleeve pipe is greater than the frictional resistance (because wear-resistant sleeve and long semicircle inner sleeve can rotate relatively) between wear-resistant sleeve and long semicircle inner sleeve, do not turn so wear-resistant sleeve is static relative to sleeve pipe, wear-resistant sleeve rotates relative to long semicircle inner sleeve, and all have employed wear-resisting measure, so just can reduce casing wear, also reduce drilling rod and drill pipe tool joint loss simultaneously.
