Abstract
An anticorrosive anti-wear oil-pumping polish rod belongs to the oil equipment field. The polished rod is a cylinder, the two ends of the cylinder are provided with outer screws in order to connect with a oil-pumping rod joint, and the surface of the polished rod has hot spray with the corrosion and wearing resistant coating. The polished rod coating can greatly reduce the corrosion and wearing degree of the surface of the polished rod when working on the oil field, and the breaking of the polished rod of the oil leaking of the wellhead packing are eased. The polished rod can also be used after being re-sprayed.
Description
Technical field
The utility model relates to a kind of anticorrosive wear-resistant and decreases oil pumping polish rod, belongs to the oil equipment field.
Background technology
In oil exploitation, the crude oil major part in the oil reservoir is to exploit out by the mode of artificial lift.The oil pumper sucker rod pumping of one of artificial lift oil production method is the oil production method of current extensive use both at home and abroad.Because equipment is simple, small investment, convenient management, compliance is strong, can use from producing several tons of wells to daily output 100-200 ton daily from deep-well, the oil production of the shallow well to 3000 of 200-300 rice meter, so sucker rod pumping has obtained using widely.Domestic sucker rod pumping accounts for artificial lift about 90% of the total well number that recovers the oil.The quality that this shows the sucker rod pumping equipment performance has very important effect in field of petroleum exploitation.
Sucker rod pumping equipment mainly comprises ground oil pumper, down-hole sucker rod and oil well pump.And as the oil pumping polish rod of one of sucker rod pumping critical component, because oil pumper misaligns, well head factor such as misalign is worn and torn with packing; add the corrosion of atmosphere and down-hole medium; its surface etch pit occurs through regular meeting, causes the packing leakage of oil, reduces oil pumping machine oil pumping efficient.Simultaneously, the etch pit on surface etc. can become the fatigue crack source, has increased the possibility of polished rod fracture, and the result will cause implementing workover treatment, and workover treatment has also been lost output simultaneously except that introducing the well workover expense.
Summary of the invention
The purpose of this utility model is to provide a kind of anticorrosive wear-resistant to decrease oil pumping polish rod, and it can overcome above-mentioned shortcoming, mainly in polished rod surface heat spraying one deck anticorrosive wear-resistant coating, the corrosion of polished rod and the degree of wear is descended greatly.Can also spray again in case polished rod loses efficacy, use repeatedly.
It is a cylinder that anticorrosive wear-resistant decreases oil pumping polish rod, and there is external screw thread at cylindrical two ends, can be connected with rod collar, decreases coating at polished rod external surface spraying one deck anticorrosive wear-resistant.
The advantage that anticorrosive wear-resistant decreases oil pumping polish rod is that the polished rod outer surface heat sprays the anticorrosive wear-resistant damage coating that a layer thickness is 0.1-0.6mm, makes corrosion and wearing and tearing be confined to coating itself.And make the unlikely wearing and tearing of polished rod itself, and avoided the polished rod corrosion, fracture, phenomenons such as packing leakage of oil can improve the economic benefit in oil field.
Description of drawings:
Accompanying drawing 1. anticorrosive wear-resistants decrease the oil pumping polish rod schematic diagram
By accompanying drawing 1, polished rod (3) is a cylinder, and all there is screw thread (1,4) at two ends, can with being threaded of rod collar.At polished rod (3) external surface hot-spraying technique, spraying one deck abrasion-proof corrosion-proof coating (2), its thickness is 0.1-0.6mm.
The specific embodiment:
At first carry out blasting treatment on polished rod (3) surface, with eliminated rust in the polished rod surface alligatoring and activation processing, spray the self-fluxing nature nickel-chromium hard alloy powder of one deck 0.1-0.6mm thickness then on the polished rod surface, coating densification and corrosion resistant that this powder produces, smooth surface, have good self-lubricating property and minimum coefficient of friction, thereby reach the purpose of wear resistant corrosion resistant.
Coating material is a self-fluxing nature nickel-chromium hard alloy powder, and composition is: chromium 8-20%, iron 0-15%, silicon 0-10%, boron 0-10%, carbon 0-1%, nickel 44-92%.
Do surperficial remelting later on again in hot spraying and handle, coating and base material bond strength are improved.
Claims (3)
1. corrosion-resistant, a wear-resistant sucker rod polished rod is characterized in that polished rod (3) is a cylinder, and there are external screw thread (1) and external screw thread (5) in two ends, in polished rod (3) external surface spraying one deck anticorrosive wear-resistant coating (2).
2. polished rod according to claim 1 is characterized in that the thickness of coating (2) is 0.1-0.6mm.
3. polished rod according to claim 1 is characterized in that coating use self-fluxing nature nickel-chromium hard alloy powder, and its composition is: chromium 8-20%, iron 0-15%, silicon 0-10%, boron 0-10%, carbon 0-1%, nickel 44-92%.
