Abstract
The utility model relates to a sleeve wear-resistant connector, which comprises a connector body (1) and a wear-resistant sleeve (4) which is installed on the connector body (1) through a sliding bearing (2) and a back cap (3). Rolling bearings for preventing axial wear are respectively arranged at the upper end and the lower end of the wear-resistant sleeve (4). The sleeve wear-resistant connector can not only reduce the abrasion caused by the radial force of a drill pipe, a well wall and the sleeve, but also can prevent the wear caused by the axial force among the drill pipe, the well wall and the sleeve, and between the connector body and the wear-resistant sleeve, and has better wear-resistant effect and longer service life.
Description
Technical field
The utility model relates to petroleum machinery, particularly a kind of blast joint that prevents the drill rod abrasion sleeve pipe and the borehole wall.
Background technology
The sleeve pipe blast joint is at directional well; dark straight well; horizontal well is especially in the extended reach well drilling process; be used to prevent friction mutually between the drilling rod and the borehole wall and the sleeve pipe; problems such as the moment of torsion transmission loss is big; it is installed between two drilling rods; link to each other with drilling rod with standard A PI tool joint thread; its box cupling external diameter is greater than the tool joint external diameter; internal diameter is equal to the tool joint internal diameter; drilling rod is played a supporting role; thereby reduced when drilling rod rotates and the direct contact wear of sleeve pipe; thereby protective casing and drilling rod; radially adopt the carbide alloy sliding shaft sleeve between the fittings body of existing sleeve pipe blast joint and the wearing bush; utilize rotation between fittings body and the wearing bush to replace sliding friction between drilling rod and the sleeve pipe; thereby reach the purpose that reduces the moment of torsion transmission loss; it only drilling rod and the borehole wall and sleeve pipe radially between have anti-wear effect; can not prevent axial wearing and tearing between the drilling rod and the borehole wall and sleeve pipe and the axial wearing and tearing between fittings body and wearing bush; its anti-wear effect is good inadequately, and be restricted application life.
The utility model content
Technical problem to be solved in the utility model is the above-mentioned shortcoming at existing sleeve pipe blast joint, provide a kind of can axial antiwear sleeve pipe blast joint.
Technical solution of the present utility model is: it comprises fittings body and is installed in the wearing bush on the fittings body by sliding bearing, back of the body cap, is respectively equipped with in the top and bottom of wearing bush and prevents the axially rolling bearing of wearing and tearing.
Technique effect of the present utility model is: it can reduce the wearing and tearing that the radial load of drilling rod and the borehole wall and sleeve pipe causes, can prevent to reach between the drilling rod and the borehole wall and sleeve pipe the wearing and tearing that the axial force between fittings body and wearing bush is brought again, its anti-wear better effects if, longer service life.
Description of drawings
Accompanying drawing is the utility model embodiment sectional view.
The specific embodiment
As shown in the figure, it comprises fittings body 1 and is installed in the wearing bush 4 on the fittings body 1 by sliding bearing 2, back of the body cap 3, is respectively equipped with in the top and bottom of wearing bush 4 and prevents the axially rolling bearing of wearing and tearing.
The top that back of the body cap 3 is positioned at wearing bush 4 is installed on the fittings body 1.
The rolling bearing that is positioned at wearing bush 4 upper ends comprises the last rolling steel balls 5 that is arranged in ring-type, and the inwall of the upper end of wearing bush 4 is provided with steel ball rolling channel 41 on the annular between wearing bush 4 and back of the body cap 3 and the fittings body 1, and last rolling steel balls 5 is positioned at steel ball rolling channel 41.
The rolling bearing that is positioned at wearing bush 3 lower ends comprises the following rolling steel balls 6 that is arranged in ring-type, be respectively equipped with steel ball rolling channel 42,12 under the annular between wearing bush 3 and the fittings body 1 on the inwall of the lower end of wearing bush 3 and on the upper surface of the wearing bush of fittings body installation shoulder 11, following rolling steel balls 6 is positioned at steel ball rolling channel 42,12 down.
Be axially arranged with brace rod 43 on the outer wall of wearing bush 4.
Fittings body 1 be axially arranged with through hole 13, the top and bottom of fittings body 1 are respectively equipped with and connect inside tapered thread 14 and be connected outer cone thread 15.
Back of the body cap 3 is installed in by screw thread on the outer wall of fittings body 1, hexagonal awl end holding screw 7 in being provided with between back of the body cap 3 and the fittings body 1.
Sliding bearing 2 is the coated with hard alloy.
Because the external diameter of wearing bush 4 is greater than the external diameter of fittings body 1, drill string contacts with the borehole wall with sleeve pipe by wearing bush 4, most of drilling rod does not produce with the borehole wall with sleeve pipe and contacts, when rotating disk drives drill string rotating, wearing bush 4 is radially keeping relative static with the sleeve pipe and the borehole wall, therefore the sliding-contact of drilling rod and the sleeve pipe and the borehole wall is replaced by relatively rotating between fittings body 1 and journal bearing, significantly reduced the loss of machine of torque that drill string transmits, and axial force is born by axial antifriction bearing.Roll and the two kinds of bearings that slide owing to adopted simultaneously, thereby the application life of having improved the sleeve pipe blast joint greatly.
The superiority of this sleeve wear-resistant connector is:
Reduce moment of torsion: owing to formed with sleeve wear-resistant connector between the drilling rod of Free and sleeve pipe and the borehole wall Be the isolation position of supporting, make ground drive rotation torque and reduce more than 20%.
Reduce drilling rod and casing wear: owing to effectively prevented the direct of drilling rod and the borehole wall, drilling rod and sleeve pipe Contact, thereby reduced the friction of drilling rod and sleeve pipe.
Reduce friction: owing to effectively reduced the friction contact force of drilling rod and the borehole wall and sleeve pipe, thus make Drilling rod is sent into resistance and is greatly reduced.
Increase drilling ability: under present drilling equipment and drilling tool condition, this joint has reduced the torque load of drill string, the drill string safety factor is improved, thereby increased drilling ability (especially extended reach well).
Increase drilling speed: effectively creep into the increase of moment of torsion and the reduction of frictional resistance and help the pressure of the drill and moment of torsion transmission, improve rate of penetration.
Save cost: the application of sleeve pipe blast joint, accelerate bit speed, avoid the wearing and tearing of drilling rod and sleeve pipe, shortened the activity duration, for drilling engineering is saved cost.
The sleeve pipe blast joint is that the drilling engineering scene provides powerful technical support with its superior performance, send aspects such as boring the mill resistance that remarkable outstanding effect is arranged in abrasion protection, reduction driving rotation torque, the reduction of drilling rod and sleeve pipe.
The new casing blast joint can be according to the needs of engineering site, for high-inclination directional well, horizontal well, conventional directional well, deep-well, sidetracked hole etc. provide service.
