Abstract
It the utility model is related to a kind of anticorrosion antiwear oil-extractor polish-rod, it is characterised in that：CrMo basic units, NiAl tack coats and the TiCN coats on body of rod surface are sprayed at including the body of rod and successively.The utility model design science is reasonable, oil-extractor polish-rod bond strength with CrMo basic units, NiAl tack coats and TiCN coats is high, with high corrosion resistance and wearability, strengthen service life, corrosion and the wear problem on oil-extractor polish-rod surface are can effectively solve the problem that, there is good prospects for commercial application.
Description
Technical field
The utility model belongs to field of oil field oil extraction, is related to oil-extractor polish-rod, more particularly to a kind of anticorrosion antiwear oil pumper
Polished rod.
Background technology
With deepening continuously for oil field secondary oil recovery exploitation, most oil well enters high water-cut stage, and rod-pumped well generally occurs
The corrosive wear problem of polished rod, cause not tight polished rod eccentric wear, packing_seal, well head packing seepage and the abrasion of rubber packing etc. one
Series of problems, it have impact on the normal clean manufacturing of oil well.In order to ensure surrounding enviroment are not polluted in the production of oily area and do not increase work
The workload of people, therefore it is badly in need of the corrosive wear for solving the problems, such as anticorrosion antiwear oil-extractor polish-rod, propose and take corresponding effective
Prevent and treat and slow down the measure of corrosive wear speed.
Currently, oil machine polished rod surface is commonly electrodeposited chromium layers and electroplated.However, oil-extractor polish-rod is ground in burn into for a long time
Worked under the operating mode of damage, due to the change of DP technology and oil, contain H in the fluid contacted with polished rod, aqueous2S、O2Deng strong
Korrosionsmedium, conventional chromate layer can not meet the requirement for anticorrosion on polished rod surface, simultaneously because polished rod for a long time with sealing wellhead
Packing contact rubs, and the grains of sand in pit and fluid and aqueous caused by corrosion will accelerate the abrasion of packing and polished rod, finally
Polished rod fails because corroding and wearing.
Therefore, need a kind of intensity height badly, there is extremely strong corrosion-resistant and anti-wear performance oil-extractor polish-rod, oil pumping can be extended
The bulk life time of machine polished rod and packing, the energy consumption of oil pumper is reduced, solve traditional oil-extractor polish-rod surface corrosion and abrasion is asked
Topic.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of bond strength is high, it is extremely strong resistance to have
Corrosivity and wearability, and the anticorrosion antiwear oil-extractor polish-rod that can increase the service life.
The utility model solves its technical problem and is achieved through the following technical solutions：
A kind of anticorrosion antiwear oil-extractor polish-rod, it is characterised in that：The CrMo on body of rod surface is sprayed at including the body of rod and successively
Basic unit, NiAl tack coats and TiCN coats.
Moreover, the coating thickness of the NiAl tack coats is 30~50 μm.
Moreover, the coating thickness of the TiCN coats is 20~30 μm.
The advantages of the utility model and have the beneficial effect that：
1st, anticorrosion antiwear oil-extractor polish-rod of the present utility model, including the body of rod and the CrMo bases for being sprayed at body of rod surface successively
Layer, NiAl tack coats and TiCN coats, NiAl tack coats can effectively strengthen TiCN coats and the oil-extractor polish-rod body of rod
Bond strength, the hardness of oil-extractor polish-rod is improved, and there is higher wear-resisting, decay resistance, can effectively solve the problem that oil pumper
The corrosion of polished rod and wear problem, strengthen the service life of oil-extractor polish-rod.
2nd, anticorrosion antiwear oil-extractor polish-rod of the present utility model, the coating thickness of NiAl tack coats is 30~50 μm, TiCN
The coating thickness of coat is 20~30 μm, and uniform, shape is sprayed in the range of the coating thickness, between each layer of oil-extractor polish-rod
Into oil-extractor polish-rod outer layer it is clean and tidy, hardness and intensity can be ensured.
3rd, the utility model design science is reasonable, has the oil pumper of CrMo basic units, NiAl tack coats and TiCN coats
Polished rod bond strength is high, has high corrosion resistance and wearability, can effectively solve the problem that oil-extractor polish-rod surface corrosion and
Wear problem, strengthen service life, there is good prospects for commercial application.
Brief description of the drawings
Fig. 1 is the structural representation of utility model.
1- oil-extractor polish-rods, 2-TiCN coats, 3-NiAl tack coats, 4-CrMo basic units, the 5- bodies of rod.
Embodiment
Below by specific embodiment, the utility model is described in further detail, following examples be it is descriptive, no
It is limited, it is impossible to which the scope of protection of the utility model is limited with this.
A kind of anticorrosion antiwear oil-extractor polish-rod 1, it is characterised in that：It is sprayed at including the body of rod 5 and successively body of rod surface
CrMo basic units 4, NiAl tack coats 3 and TiCN coats 2, CrMo basic units are sprayed on pre- through polishing after being mixed by Cr, Mo powder
The body of rod surface managed, NiAl tack coats are formed by reaction and plasma spray gun spraying Al/Ni powder in CrMo basic units, TiCN coatings
Layer uses reaction and plasma spray gun spraying after being mixed by Ti powder and C powder ratio, N in spraying process2Make powder feeding gas, NiAl is bonded
Layer can effectively strengthen the bond strength of TiCN coats and the oil-extractor polish-rod body of rod, improve the hardness of oil-extractor polish-rod, and have
There are higher wear-resisting, decay resistance, can effectively solve the problem that corrosion and the wear problem of oil-extractor polish-rod, strengthen oil-extractor polish-rod
Service life.
The coating thickness of NiAl tack coats is 30~50 μm, in the range of the coating thickness, each layer of oil-extractor polish-rod it
Between spray uniform, the oil-extractor polish-rod outer layer of formation is clean and tidy, can ensure hardness and intensity.
The coating thickness of TiCN coats is 20~30 μm, in the range of the coating thickness, each layer of oil-extractor polish-rod it
Between spray uniform, the oil-extractor polish-rod outer layer of formation is clean and tidy, can ensure hardness and intensity.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, those skilled in the art can be with
Understand：Do not departing from the utility model and spirit and scope of the appended claims, it is various replace, change and modifications all be can
Can, therefore, the scope of the utility model is not limited to embodiment and accompanying drawing disclosure of that.
