Abstract
The invention relates to a wear-resisting sheath structure for a drill stem. The structure comprises a drill stem connection sleeve connected by threads and a wear-resisting layer outside the drill stem connection sleeve, wherein the drill stem connection sleeve and the wear-resisting layer are cylindrical; a limit block is arranged on the inner side of the non-connection end of the wear-resisting layer; an inner taper sleeve and an outer taper sleeve which are matched mutually are arranged between the drill stem connection sleeve and the wear-resisting layer and are matched with each other by using a conical surface, and a check ring is arranged at the position where the rear part of the inner taper sleeve is contacted with the drill stem connection sleeve; and an annular groove for increasing frictional resistance is formed on the inner side of the bore diameter of the inner taper sleeve. The sheath structure is simple, is locked with a stem body mechanically by the assembly of parts and is connected reliably, and the number of arranged sheaths can be increased or decreased according to the length of the stem body; and the sheath structure can be applied to the installation of stem bodies with different apertures.
Description
Technical field
The present invention relates to a kind of drilling rod wear-resistant jacket structure.
Background technology
In wellbore construction, because drilling rod rotation at a high speed in the hole, and annular space is less between the hole wall, and the grinding that is easy to form is crept into, and makes the drilling rod surface abrasion serious, thereby influences the working strength of drilling rod.Especially when the geologic drilling rod of aluminium alloy material, though characteristics such as that the drilling rod of this kind material has is in light weight, good toughness, intensity height, the nonferromagnetic substance of material is relatively poor, and drilling rod is serious wear in use.Traditional this low-melting material of metal surface coated aluminium alloy technology is inapplicable, therefore can only be by increasing the mode of sheath mechanism, and first grinding skin reduces the grinding total amount of drilling rod through the sheath of the increasing external diameter of cure process.
Summary of the invention
Based on foregoing, the invention provides a kind of drilling rod wear-resistant jacket structure, solve the wear-resisting problem of stabilizer.
The objective of the invention is to be achieved through the following technical solutions:
A kind of drilling rod wear-resistant jacket structure, comprise with drilling rod adapter sleeve that is threaded and outside wearing layer, drilling rod adapter sleeve and wearing layer all are tubular, the inboard of the front of motor of wearing layer is provided with limited block, inner conical drogue and the external conical sleeve that cooperatively interacts is installed between drilling rod adapter sleeve and wearing layer, described inner conical drogue and external conical sleeve adopt cone match, and the rear portion of inner conical drogue is provided with back-up ring with the position that the drilling rod adapter sleeve contacts; There is the cannelure that increases frictional resistance inboard, inner conical drogue aperture.
Because the aluminium drill pipe two ends are local thickenings, the outside dimension of end is greater than body of rod outside dimension, this sheath is again to be contained on the body of rod, therefore in order to pass through the large-diameter portion branch at body two ends smoothly, this jacket structure has five component to be formed, and is respectively inner conical drogue, external conical sleeve, back-up ring, drilling rod adapter sleeve and wear-resistant sleeve.
Part all adopts through heat treated Summoning material, and wherein there is the cannelure that increases frictional resistance inboard, inner conical drogue aperture, and assurance a bit contacts when meshing with the body of rod all the time, has guaranteed the switching performance with the body of rod.
Being meshing with each other of the conical surface between inner conical drogue, the external conical sleeve utilized the self-locking property of the conical surface, prevents to get loose with drilling rod, and drilling rod makes the tapered sleeve and the body of rod change tighter and tighter when rotating in the direction of the clock.
The form of the semicircle card that back-up ring adopts is convenient to install, and main effect is to prevent that inside and outside tapered sleeve from skidding off from body of rod adapter sleeve.
Adopt fine thread to be connected between body of rod adapter sleeve and the wear-resistant sleeve, fully guarantee the reliability of connection.
The case hardening treatment process is adopted on the wear-resistant sleeve surface, strengthens the abrasion resistance on surface, and the external diameter of wear-resistant sleeve joint the external diameter general and body of rod is suitable even slightly larger, can protect drilling rod not to be worn like this.
This jacket structure is simple in structure, finishes mechanical interlocking mode with the body of rod by the assembling of spare and accessory parts, connect reliable, and the tricks that can install according to the length increase and decrease of the body of rod, the body of rod that can be applicable to different bores is simultaneously installed.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of a kind of drilling rod wear-resistant jacket structure of the present invention;
The specific embodiment
As shown in Figure 1, a kind of drilling rod wear-resistant jacket structure, comprise with drilling rod adapter sleeve 1 that is threaded and outside wearing layer 2, drilling rod adapter sleeve 1 and wearing layer 2 all are tubular, the inboard of the front of motor of wearing layer 2 is provided with limited block 6, inner conical drogue 3 and the external conical sleeve 4 that cooperatively interacts is installed between drilling rod adapter sleeve 1 and wearing layer 2, and described inner conical drogue 3 and external conical sleeve 4 adopt cone match, and the position that the rear portion of inner conical drogue 3 contacts with the drilling rod adapter sleeve is provided with back-up ring 5; There is the cannelure that increases frictional resistance inboard, inner conical drogue 3 aperture.
Because the aluminium drill pipe two ends are local thickenings, the outside dimension of end is greater than body of rod outside dimension, this sheath is again to be contained on the body of rod, therefore in order to pass through the large-diameter portion branch at body two ends smoothly, this jacket structure has five component to be formed, and is respectively inner conical drogue, external conical sleeve, back-up ring, drilling rod adapter sleeve and wear-resistant sleeve.
Part all adopts through heat treated Summoning material, and wherein there is the cannelure that increases frictional resistance inboard, inner conical drogue aperture, and assurance a bit contacts when meshing with the body of rod all the time, has guaranteed the switching performance with the body of rod.
Being meshing with each other of the conical surface between inner conical drogue, the external conical sleeve utilized the self-locking property of the conical surface, prevents to get loose with drilling rod, and drilling rod makes the tapered sleeve and the body of rod change tighter and tighter when rotating in the direction of the clock.
The form of the semicircle card that back-up ring adopts is convenient to install, and main effect is to prevent that inside and outside tapered sleeve from skidding off from body of rod adapter sleeve.
Adopt fine thread to be connected between body of rod adapter sleeve and the wear-resistant sleeve, fully guarantee the reliability of connection.
The case hardening treatment process is adopted on the wear-resistant sleeve surface, strengthens the abrasion resistance on surface, and the external diameter of wear-resistant sleeve joint the external diameter general and body of rod is suitable even slightly larger, can protect drilling rod not to be worn like this.
This jacket structure is simple in structure, finishes mechanical interlocking mode with the body of rod by the assembling of spare and accessory parts, connect reliable, and the tricks that can install according to the length increase and decrease of the body of rod, the body of rod that can be applicable to different bores is simultaneously installed.
This sheath mechanism can be used for the installation of finished product drilling rod, increases the number of installing as required, also can select the suitable sheath sizes of grating according to the size of drill pipe diameter.
