Abstract
The utility model relates to a stabilizer of hard alloy block type drill, mainly comprising a main body 1 and a hard alloy block 3. The main body 1 is provided with 3-4 spiral type righting bands 2, the surface of each righting band 2 is respectively milled with a groove 4, and the hard alloy block 3 is staggered and welded in the groove 4. The utility model has the advantages of favorable abrasive resistance, low cost, high service life and good righting performance. Compared with the hard alloy column, the utility model can save dosage of the hard alloy and process the special sticking accidents of the drill tool.
Description
The utility model belongs to drilling tool, particularly relates to a kind of seting welding carbide piece formula drilling tool stabilizer that oil drilling is used.
Drilling tool stabilizer is one of necessary tool in the oil drilling, and the surface abrasion resistance problem that solves drilling tool stabilizer is to improve the key in its life-span.At present, the home and abroad is in the surface abrasion resistance problem that solves stabilizer, and great majority are the modes that adopt interference fit, high-abrasive materials such as hard zygostyle are embedded in the surface of stabilizer.But, because it is interior deep that hard alloy columnar is embedded in the body of stabilizer, when the drilling well bit freezing takes place when, in jarring, when method such as lift is invalid, the normal mode Treating Jammed Bit Accident that adopts cover to mill, it is exactly with stabilizer extexine mill off that cover mills, so that loosening drilling tool, therefore but inlay deeplyer because of hard alloy columnar, cover mills quite difficulty, often causes drilling well to scrap accident.
The purpose of this utility model is in order to overcome the existing existing shortcoming of stabilizer, not only to improve the abrasion resistance of drilling tool stabilizer but also can be handled easily when having an accident, so designed a kind of seting welding carbide piece formula drilling tool stabilizer.
Particular content of the present utility model is:
Seting welding carbide piece formula drilling tool stabilizer, mainly formed by body 1 and hard alloy blocks 3, on body 1, be provided with spiral the setting upright of 3-4 bar and be with 2, be milled with groove 4 respectively on every surface of setting upright with 2, hard alloy blocks 3 is staggered put and welding-on in groove 4.
The utility model has the advantages that: anti-wear performance is good, high life, and it is good to set upright performance, can save the consumption of carbide alloy with the hard alloy columnar comparison, reduces production costs, and it is convenient to handle when meeting special lock of tool drilling.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A generalized section of setting upright with 2;
Fig. 3 be the B of Fig. 2 to view, both discharging schematic diagrames of hard alloy blocks 3.
Introduce most preferred embodiment of the present utility model with reference to the accompanying drawings in detail:
The utility model is relatively simple for structure, implement also not difficult, can be at every groove that mills out on setting upright with 24 according to user's requirement processing, in the harder area of geological formations, groove 4 can mill several the welding-on areas with increase hard alloy blocks 3 more, and increases the abrasion resistance of drilling tool stabilizer, in the softer area of geological formations, the cell wall of groove 4 is suitably widened, and the welding-on quantity of hard alloy blocks 3 will reduce relatively, thereby reduce cost of production.Hard alloy blocks 3 adopts the mode of staggered discharging, has both increased the bond strength behind the welding-on, and large tracts of land comes off in the time of can avoiding meeting the ultrahard sillar again.After with hard alloy blocks 3 welding-ons, more whole drilling tool stabilizer is carried out Cylindrical Grinding Processes, to guarantee concentricity.
