Description
Technical field
The invention belongs to oil-field floodings to combine defective valve surface repairing method technical field, and in particular to a kind of laser melting coating
Powder further relates to a kind of side that water-flooding pump for oil field combination defective valve surface is repaired using the powder and ultrahigh speed laser melting and coating technique
Method.
Background technique
The oil well of Changqing oilfields generallys use the method for high pressure water injection since strata pressure is smaller to drive in oil recovery process
Oil stream is flowed out to oil well, and water injection pressure is generally in 15MPa-25MPa, and the combination valve surface of water injecting pump subjects high pressure liquid in the process
Body washes away.In addition, the injecting process have clear water injection and sewage inject two types, wherein sewage there are higher sulfide,
Hydride, chloride and bacterium can corrode the surface of combination valve.Under normal circumstances, the material that oil equipment uses is middle carbon
The wear and corrosion resistance of Steel material, such material is poor, under the compound action washed away and corroded, combination valve surface easily by
It damages and fails.Combination valve is the core component of water injecting pump, and pumping the flow velocity of interior liquid and pressure to control has important role.
If combination valve surface damage is serious, it will cause the declines of the sealing performance of water injecting pump, so as to cause oil recovery efficiency reduction.
Defective valve this problem is combined for petroleum water injecting pump, current main solution has following several:
(1) it is repaired using plasma spray technology, it is mechanical knot that the disadvantage of this technology, which is between coating and matrix,
It closes, binding force is poor, generally 50-100MPa, is easy to peel off；In addition, since the coating stomata of thermal spraying preparation is more, it is necessary to adopt
It is prepared with plane SH wave mode, causes processing efficiency to reduce in this way, and process dusty material and gas consumption are larger, material
Utilization rate maximum only has 50% or so.
(2) it is repaired using technique for overlaying, this technological deficiency is that part needs to preheat, and heat affected area is larger, in material
Material is internal to generate biggish residual stress, easily causes part deformation, and influence the mechanical performance of material.
(3) it is repaired using traditional laser melting and coating technique, this technology has bond strength high, and heat affected area is small etc.
Advantage starts to realize application, but traditional lower (generally 0.5~3m/ of laser melting coating rate at present in all conglomeraties
Min), and after cladding coating roughness is larger, it is also necessary to which such as turning machining guarantees part dimension accuracy, therefore produces
Inefficiency.Simultaneously in order to prepare Large area coatings faster, traditional laser cladding method uses raising laser power and increasing
Add the method for facula area, but excessively high power will increase the temperature gradient for being repaired interiors of products, causes to occur after processing
Deformation.Due to its inefficiency, at high cost, its extensive industrial application is limited, and bottleneck urgently to be resolved at present is asked
Topic.
