Abstract
The invention relates to a non-magnetic drill collar with wear-resistant belts. The non-magnetic drill collar with the wear-resistant belts comprises a non-magnetic drill collar body which is made of full-austenite stainless steel; one end of the non-magnetic drill collar body is provided with an internal thread connector connected with a drill rod, and the other end of the non-magnetic drill collar body is provided with an external thread connector connected with the drill rod; two circles of the wear-resistant belts are arranged around the outer circumferential surface of the non-magnetic drill collar body, and an imprint groove used for being printed with a product model is formed in the middle position of the non-magnetic drill collar. In the use process, the non-magnetic drill collar firstly makes contact with the wall of a well, the pressure produced when the non-magnetic drill collar makes contact with the wall of the well is reduced, or the non-magnetic drill collar does not make contact with the wall of the well, and the wear velocity of the non-magnetic drill collar is effectively decreased; when the wear-resistant belts are gradually worn in the use process, a layer of the wear-resistant belt can still be spray-welded again by adopting a spray-welding method to continuously and lastingly protect the non-magnetic drill collar, the service life of the non-magnetic drill collar is greatly prolonged, and the non-magnetic drill collar with the wear-resistant belts can be widely applied to the field of non-magnetic drill collars.
Description
Technical field
The invention belongs to oil drilling tools manufacture field, be specifically related to a kind of non magnetic drill collar with wear-resistant strip.
Background technology
China's oil demand constantly promotes, and oil drilling drilling depth rapidly increases, and because non magnetic drill collar has extremely low magnetic conductivity, good mechanical performance and corrosion resistance, therefore also increase day by day in the demand of oil field to non magnetic drill collar.But the non magnetic drill collar used now, normally utilize stainless steel manufacture, surface does not have abrasion-proof structure, during use, non magnetic drill collar body and borehole wall direct friction cause serious wear, the application life of drill collar is shorter, serious wear will change drill collar, thus it is outstanding day by day to cause conventional non magnetic drill collar to increase the problem of drilling cost due to serious wear.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of non magnetic drill collar with wear-resistant strip, and this non magnetic drill collar can reduce the friction of non magnetic drill collar body and the borehole wall, effectively can extend the application life of non magnetic drill collar.
Technical scheme of the present invention: a kind of non magnetic drill collar with wear-resistant strip, comprise non magnetic drill collar body, one end of non magnetic drill collar body is provided with the female adapter be connected with drilling rod, the other end is provided with the male connection be connected with drill bit, outer circumference surface along non magnetic drill collar body is surrounded with two circle wear-resistant strips, and the medium position of drill collar body is provided with the marking groove for printed product model.
Further, the distance near the wear-resistant strip distance female adapter end face of female adapter is 350mm.
Further, the distance near the wear-resistant strip distance male connection circular bead surface of male connection is 300mm.
Further, the width of described wear-resistant strip is 70 ~ 110mm, and thickness is 2 ~ 4mm.
Further, described drill collar body is made up of full austenite stainless steel.
Further, the material of described wear-resistant strip is NATE7000W.
Further, described wear-resistant strip is welded on the outer circumference surface of drill collar body by spray fuse method.
The present invention compared with prior art has following beneficial effect: the present invention by welding wear-resistant strip on non magnetic drill collar, wear-resistant strip adopts NATE7000W material, intensity, hardness is high, abrasion resistance is good, in use procedure, first non magnetic drill collar contacts the borehole wall, non magnetic drill collar body reduces with borehole wall contact or does not contact, effectively reduce the rate of wear of non magnetic drill collar, after wear-resistant strip is in use gradually worn down, still spray fuse method surfacing one deck wear-resistant strip more again can be adopted, to continue to protect non magnetic drill collar lastingly, drastically increase the application life of non magnetic drill collar, non magnetic drill collar field can be widely used in.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-female adapter, 2-marking groove, 3-male connection, 4-wear-resistant strip.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further illustrated.
Have a non magnetic drill collar for wear-resistant strip, comprise non magnetic drill collar body, described drill collar body is made up of full austenite stainless steel.As shown in Figure 1, one end of non magnetic drill collar body is provided with the female adapter 1 be connected with drilling rod, the other end is provided with the male connection 3 be connected with drill bit, outer circumference surface along non magnetic drill collar body is surrounded with two circle wear-resistant strips 4, being 350mm near the wear-resistant strip 4 of female adapter apart from the distance of female adapter end face, is 300mm near the wear-resistant strip 4 of male connection apart from the distance of male connection circular bead surface.The width of described wear-resistant strip is 101mm, and thickness is 2.4mm, and the material of described wear-resistant strip is NATE7000W.Wear-resistant strip 4 is welded on the outer circumference surface of drill collar body by spray fuse method.In use procedure, the quantity of wear-resistant strip can also be set according to actual needs on drill collar body.The medium position of drill collar body is provided with the marking groove 2 for printed product model.
The material adopted due to described wear-resistant strip 4 is NATE7000W; its intensity, hardness are high; abrasion resistance is good; in use procedure, first non magnetic drill collar contacts the borehole wall, and non magnetic drill collar body reduces with borehole wall contact or do not contact, and effectively reduces the rate of wear of non magnetic drill collar; after wear-resistant strip is in use gradually worn down; still can adopt spray fuse method surfacing one deck wear-resistant strip more again, to continue to protect non magnetic drill collar lastingly, drastically increase the application life of non magnetic drill collar like this.
Above-described embodiment only understands technical scheme of the present invention for those skilled in the art, and is not limitation of the present invention, all do on the basis of the technical program any amendment, replacement or improvement, all should be included within protection scope of the present invention.
