Abstract
The utility model discloses a wear-resistant belt surface dressing-welding type centralizer, and aims to provide a novel centralizer on which a wear-resistant belt with a more wear-resistant surface is welded through flame. A wear-resistant surfacing dressing is used for surfacing a tungsten carbide alloy block on the outer surface of a centralizing belt, and the coverage of the tungsten carbide alloy block on the outer surface of the centralizing belt is over 60 percent. The surfacing dressing is special tungsten carbide powder. The centralizer has stronger strength and higher hardness, toughness and wear resistance, the surface of the wear-resistant belt of the centralizer is wear-resistant and difficult to separate, and the service life of the centralizer is prolonged by 25 percent compared with that of an alloy post embedded stabilizer; the centralizer is easy to maintain, the working diameter of the wear-resistant belt can be conveniently recovered to an original working diameter after being abraded, and the centralizer can be used for many times, so that the drilling production cost is greatly lowered.
Description
Technical field
The utility model relates to a kind of centralizer, particularly relates to the surface weldering of a kind of wear-resistant strip and covers formula centralizer.
Background technology
Existing centralizer wear-resistant strip technology is on the cylindrical wear-resistant strip surface of centralizer working diameter, to get out in advance the hole than the little 0.25-0.35mm of carbide alloy diameter, then cold carbide alloy edge in alloy hole.This technology, when repairing the size of original working diameter after the wearing and tearing of centralizer working diameter, cannot be removed fast because stud with carbide alloy in matrix, even if it is also very time-consuming to change small-sized centralizer, loses more than gain.Inserted stabilizer easily makes alloy column come off in drilling process, and damages drill bit.
Utility model content
The purpose of this utility model: being to design a kind of wear-resistant strip is to connect and make the more wear-resisting a kind of wear-resistant strip surface weldering in surface to cover formula centralizer by flame welding.
The technical scheme that the utility model adopts is:
Formula centralizer is covered in the surface weldering of a kind of wear-resistant strip, comprises drill string, and three wearable correcting band spirals are arranged on drill string external surface, and diamondite piece is welded in wearable correcting band external surface by hardfacing dressing homogeneous reactor.
Formula centralizer is covered in above-mentioned wear-resistant strip surface weldering, and righting band external surface diamondite piece area coverage reaches more than 60%.
Formula centralizer is covered in the surface weldering of above-mentioned wear-resistant strip, and built-up welding dressing is a kind of tungsten-carbide powder.
The utility model is to adopt weldering coating technique that hard alloy blocks weldering is overlayed on to centralizer wearable correcting band working surface centralizer working surface wear-resistant strip, by hardfacing dressing, diamondite piece heap is soldered to wearable correcting band external surface.Wearable correcting band external surface diamondite piece area coverage reaches more than 60%.Built-up welding dressing is a kind of special tungsten-carbide powder.
The beneficial effects of the utility model are:
1, external surface has higher intensity, hardness and toughness, has guaranteed that righting band external surface is not only wear-resisting but also do not come off in down-hole.Improve 25% the application life than embedded alloy pillar stabilizer.
2, for ease of maintenaince, after the wearing and tearing of wear-resistant strip working diameter, can repair easily original working diameter, can repeatedly use, thereby greatly reduce drilling well cost of production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in Fig. 1 the local A-A of wearable correcting band to enlarged diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, formula centralizer is covered in the surface weldering of a kind of wear-resistant strip, comprises that 1, three wearable correcting band 2 spiral of drill string are arranged on drill string external surface, and diamondite piece 3 is welded in wearable correcting band external surface by hardfacing dressing homogeneous reactor.Righting band external surface diamondite piece area coverage reaches more than 60%, extremely wear-resisting.Built-up welding dressing is a kind of tungsten-carbide powder, and postwelding has higher intensity hardness and toughness, has guaranteed that righting band external surface is not only wear-resisting but also do not come off in down-hole.
Claims (3)
1. formula centralizer is covered in a wear-resistant strip surface weldering, it is characterized in that: comprise drill string (1), article three, wearable correcting band (2) spiral is arranged on drill string external surface, and diamondite piece (3) is welded in wearable correcting band external surface by hardfacing dressing homogeneous reactor.
2. formula centralizer is covered in wear-resistant strip according to claim 1 surface weldering, it is characterized in that: righting band external surface diamondite piece area coverage reaches more than 60%.
