Background technology
Tool joint is the vitals of oil drill string, and its condition of work is very severe, and stressing conditions is very complicated.It will bear stretching, and the multiple load such as vibration are reversed in bending.In addition, joint also will be subject to the corrosion of drilling fluid and stratum media in creeping into, and its outside also can be subject to serious wearing and tearing, so the raising of the sclerosis of tool joint and abrasion resistant corrosion resistant performance thereof seems particularly important.The joint of ordinary metallic material, owing to being difficult to adapt to current abrasion and corrosion environment, is eliminated gradually.
In order to improve the application life of tool joint, generally its hardness is improved, the conventional method for curing of joint of petroleum drill rod has: manual repair welding, oxygen-acetylene repairing, plasma arc powder spray welding, sulphur nitrogen Combined Processing etc.
Manual repair welding: it is directly to have wearing layer certain thickness, that 50 millimeter are wide in electric welding mode to joint repair welding, use be the welding rod that pipe fills casting carbon tungsten carbide particle.The method is the most initial the most direct sclerosis restorative procedure, but the method inefficiency, and coating quality can not guarantee.
Oxygen-acetylene repairing: with oxy-acetylene reducing flame fusing pipe dress granular carbonization tungsten electrode, form wearing layer at joint surface.This method temperature is lower, and tungsten carbide particle does not melt, and can keep abrasion resistance, oxyacetylene torch heap is welded in wearing face built-up welding and is widely used, and compares with other overlaying methods, and welding equipment is simple, flexible operation, cost of investment are low, but work efficiency is low, require the workman of specialized operations.
Plasma arc powder spray welding: the heat that utilizes argon plasma arc to produce, on tool joint surface, form molten bath, alloy powder is preheated fusing in arc column, is ejected in molten bath, by regulating parameter, can on joint, obtain the wear-resistant strip needing.The arc column of powder plasma-arc welding is stable, and heat is concentrated, and heat utilization rate is high, and controllability is good, can control heat excessive, and dilution ratio is low, but because temperature after matrix local heating in reflow process reaches 900 ℃, can produce larger thermal deformation.
Sulphur nitrogen Combined Processing: the nitride carrying out in the rear workpiece of nitriding processing has very high hardness, heat stability and the very high spread, thereby can make the steel part after nitriding obtain high case hardness, abrasion resistance, fatigue strength, seizure resistance, Chinese People's Anti-Japanese Military and Political College's gas and superheated steam corrosive power, anti-temper softening ability, and reduce notch sensitivity.Thereby ion sulfurization technology can be prepared in metal surface FeS solid lubricant layer and improve material to wear-resistant performance, therefore conventionally at the joint after nitrogen treatment, carrying out ion sulfurization processing, thereby prepare nitrogen sulphur, meet processing layer, improved the ability of surface abrasion.But nitriding or sulfurizing can not Local treatment, during upper and lower drilling rod operation, pipe wrench retaining part easily skids, and needs special power tool.In addition, combination process more complicated, cost is higher.
Laser melting coating, as a kind of advanced person's process for modifying surface, along with improving constantly of laser power and stability, is widely applied and promotes rapidly.Laser melting and coating technique refers to that with different adding material modes, on coated matrix surface, place the coating material of selecting makes it to melt with matrix surface skim through laser irradiation simultaneously, and it is extremely low after rapid solidification, to form dilution factor, become the face coat of metallurgical binding with matrix material, thereby significantly improve the process of wear-resisting, anti-corrosion, heat-resisting, the non-oxidizability etc. of substrate material surface.Now, it has become having development prospect and having much one of new technology of characteristic in Modern Surface Technology system, and is having broad application prospects in the future.And the performance of cladding layer wear-and corrosion-resistant just in time can solve the problem running in tool joint work, this,, to extending application life of tool joint, improves the operating efficiency of creeping in oil field significant.
