Abstract
The utility model belongs to assistance parts for exploration, and relates to a petroleum drill rod abrasion-proof sleeve, in particular to a petroleum drill rod rapid-replacement abrasion-proof sleeve. The petroleum drill rod rapid-replacement abrasion-proof sleeve comprises a drill rod sleeve body. Abrasion-proof bands are fixed outside the drill rod sleeve body. The drill rod sleeve body is composed of two semicircular sleeve bodies which are hinged to each other, and the other ends of the two semicircular sleeve bodies are provided with pin holes. As the mutually-hinged sleeve bodies are used, a drill rod is not required to be disassembled during installation, only the position where the petroleum drill rod rapid-replacement abrasion-proof sleeve is required to be installed is firstly required to be provided with a locating groove, then the wall of the petroleum drill rod rapid-replacement abrasion-proof sleeve is clamped in the locating groove, a locating protruding block is matched with the locating groove, and then the free ends of the semicircular sleeve bodies are fixed through a hinge pin. The petroleum drill rod rapid-replacement abrasion-proof sleeve is rapid and convenient to use, the replacement speed of the abrasion-proof bands is quickened, the well repairing work efficiency can be effectively improved, and the work load amount is relieved.
Description
Technical field
The utility model relates to oil drill rocker abrasionproof tackling, belongs to exploration auxiliary spare part, specifically a kind of oil drill rocker quick change anti-wear sleeve.
Background technology
For the drilling rod in oil drilling, in drilling process, drill string and casing wear are the problems that affects field produces exploitation always, during drill string wearing and tearing, gently reduce the application life of drill string, and the serious drilling string failure that causes, causes serious economic loss and the wasting of resources.Casing wear gently reduces casing string anti-squeeze ruin, internal pressure strength, impact drilling well subsequently. completion and mining operations quality and safety; Heavy cause casing string to squeeze and ruin, be out of shape and leak, sometimes even can cause full well to scrap.For a long time; what in field produces, use is that the technology of build-up wear-resistant band in tool joint is protected drill string and casing string; but; there is following shortcoming in this technology: (1), in drilling process; particularly, when boring the harsh wells such as deep-well, ultradeep well, horizontal well, extended reach well, wear and tear very serious, be often in the process midway of drilling well wear-resistant strip with regard to experience wear is complete; now, drilling rod cannot be retracted to base build-up wear-resistant band again.Like this, drilling rod is drilling well under the condition that there is no wear-resistant strip protection just, must cause the heavy wear of drilling rod/sleeve pipe.(2), after heap is welded in wear-resistant strip in tool joint and wear and tear, again the cycle of built-up welding grow, somewhat expensive.This is because again during build-up wear-resistant band, must first drilling rod be retracted to base, then, check whether the wear-resistant strip of wearing and tearing exists defect and whether injure body, according to circumstances carry out again repair process, reach after code requirement build-up wear-resistant band again, then move drilling rod to situ of drilling well and use.Because a set of drill string weight reaches hundreds of ton, so freight is very high, particularly for drilling well from far-off regions.(3), owing to being direct build-up wear-resistant band on cobalt bar, if welding procedure adjustment is improper in welding process, may cause the wear-resistant strip of welding defective, thereby need to again repair wear-resistant strip, just must first remove underproof wear-resistant strip, and complex process, the workload of removing defective wear-resistant strip are large, cost is high, sometimes may injure body.
As shown in Figure 1, recorded a kind of technical scheme of petroleum drill rod anti-wear sleeve in the patent No. in the file that is 200710038691, this technical scheme efficiently solves directly wear-resistant strip is welded on to the defect on drilling rod.But still exist to change the situation of wear sleeve inconvenience, and special in darker oil well, if change wear sleeve, also need drilling rod to extract out, not only workload is large but also affect the normal use in oil field, still has larger drawback.
Summary of the invention
The purpose of this utility model, is exactly the problem existing for solving prior art, and has designed a kind of oil drill rocker quick change anti-wear sleeve, can drilling rod need not extracted out and directly change wear sleeve, and replacing speed is fast, and operating efficiency is high.
The technical solution of the utility model is: a kind of oil drill rocker quick change anti-wear sleeve, comprise drilling rod sleeve body, and this external wear-resistant strip that is fixed with, described sleeve body is comprised of two half round busses that are hinged; Another free end of described two and half round busses is provided with pin-and-hole.
In order to alleviate the damage of vibrations to sleeve, the inwall of described sleeve is provided with elastic shock attenuation anti-skid rubber cushion.
For effective fixed muffle, the inwall of described sleeve is provided with at least one positioning boss.
For protection sleeve body, described sleeve body surface scribbles one deck antirust oil enamelled coating.
For fixing wear-resistant strip, described wear-resistant strip is fixed on this external surface by the mode of built-up welding.
In order to improve application life, described wear-resistant strip is arranged with three in parallel.
The beneficial effects of the utility model can draw by such scheme: use the sleeve being hinged, make will not disassemble by drilling rod when mounted.Only need first in the place that wear-resistant strip need to be installed, output locating slot, then by sleeve lining and the clamping of drilling rod wall, and make together with positioning boss coincide mutually with locating slot, to re-use bearing pin by the free end pinning of sleeve.This use is novel easy to use, quick, has improved the replacing speed of wear-resistant strip, can effectively improve the efficiency of workover treatment, and has alleviated the work amount of labour.
As can be seen here, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.

Fig. 1 is the structural representation of original anti-wear sleeve;
Fig. 2 use view of the present utility model;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is AA cross section structure schematic diagram in Fig. 3;
Fig. 5 is BB cross section structure schematic diagram in Fig. 3;
Wherein, 1 is body, and 2 is wear-resistant strip, and 3 is drilling rod, and 4 is bearing pin, and 5 is rubber pad, and 6 is positioning boss, and 7 is pin-and-hole.
the specific embodiment:
In order to understand better the utility model, below in conjunction with accompanying drawing, explain in detail embodiment of the present utility model.
The specific embodiment: a kind of oil drill rocker quick change anti-wear sleeve, comprise drilling rod sleeve body 1, sleeve body 1 surface scribbles one deck antirust oil enamelled coating.Outer being fixed with of body 1 is arranged with three wear-resistant strips 2 in parallel, and wear-resistant strip 2 is fixed on body 1 external surface by the mode of built-up welding.Described sleeve body 1 is comprised of two half round busses that are hinged; The other end of described two and half round busses is provided with pin-and-hole 7.The inwall of described sleeve is provided with elastic shock attenuation anti-skid rubber cushion 5.The inwall of described two sleeves is provided with each positioning boss 6.
When needs are changed, do not need drilling rod 3 to disassemble, only bearing pin 4 need be taken out from pin-and-hole 7, then open sleeve, new wear sleeve is clamped, re-use bearing pin 4 and fix.
