Abstract
The present invention provides the wear-resistant belt of petroleum drill rod of the Fe-based amorphous metal coating of coating, and its technical scheme is：Tool joint is cleared up, the removal of impurity and oxide is gone, snapped at away from female adapter slope disappearance position 10mm, wear-resisting welding twice, width about 50mm 60mm, layer thickness is 3mm, burr is cleared up with angle grinder or emery wheel after welding, room temperature is progressively cooled down.Present invention practicality reasonable in design, it is time saving and energy saving, with improving Life of drill rod under work condition environment more than 2 times, can the direct built-up welding on wear-resisting carrying material, it is compatible good without removing former coating.
Description
Technical field
The present invention relates to equipment coating technology field, the oil drill rocker for especially coating Fe-based amorphous metal coating is wear-resisting
Band.
Background technology
Oil drill rocker is that length is typically at 9 meters or so, in order to enter to the rod member for connecting, transmitting power in drillng operation
The drilling well of row deep is, it is necessary to get up drilling rod with threaded connection.Because with the presence of screw thread, connecting portion diameter is more than drilling rod body,
In drilling operation course, drilling rod connecting portion will produce friction with the borehole wall.In order to avoid drilling rod because wearing and tearing the thinning production that attenuates
Raw fracture is, it is necessary to coat one layer of corrosion-proof wear-resistant material, for protecting drilling rod body to preserve from.
In order to wear-resistant and drilling fluid corrosion, extend the life-span, existing wear-resisting carrying material is generally hard alloy, used
Overlaying method is coated in drilling rod junctions, and Life of drill rod is extended to a certain degree.But there is chip off-falling and come off in the wear-resisting carrying material in part
, especially there is certain risk in ultra-deep well operations, add drilling cost in phenomenon, wearing no resistance of having.
The content of the invention
The present invention provides state-of-the-art technology through putting into practice for many years, and the proprietary Fe-based amorphous alloy of LMC companies is coated to drilling rod
Joint, solves the problem of drilling life of drill pipe is short.
Non-crystaline amorphous metal is also known as liquid metal, refers to that material remains metal atom under liquid situation under solid conditions
Three dimensions it is disorderly arranged, that is, metal is without intrinsic crystal boundary, because the disappearance of crystal boundary, and conventional alloys are compared,
Corrosion resistance, hardness and the toughness of non-crystaline amorphous metal are greatly enhanced, and LiquidMetal Coating LLC companies of the U.S. are (referred to as
LMC) it is leading enterprise of the material in the global field.
By automatic surfacing technology, non-crystaline amorphous metal is coated in tool joint position, so as to greatly improve its service life.
The purpose of the present invention is achieved through the following technical solutions：Tool joint is cleared up, the removal of impurity and oxygen is gone
Compound, snaps, wear-resisting welding twice, width about 50mm-60mm, layer at away from female adapter slope disappearance position 10mm
Thickness is 3mm, burr is cleared up with angle grinder or emery wheel after welding, room temperature is progressively cooled down.
Beneficial effects of the present invention：Present invention practicality reasonable in design, it is time saving and energy saving, with improving Life of drill rod under work condition environment
More than 2 times, can the direct built-up welding on wear-resisting carrying material, without removing former coating, compatibility is good.
Figure of description
Fig. 1 is the design sketch after drilling rod wear-resistant welding.
Embodiment
As shown in figure 1, coating the wear-resistant belt of petroleum drill rod of Fe-based amorphous metal coating, tool joint is cleared up, gone
