Abstract
The utility model provides an oil well sleeve oil production device which can reduce corrosion to a sleeve and can prevent blocking. The oil well sleeve oil production device comprises an oil pipe, a sleeve, a direct current power supply and an anode, wherein the sleeve is arranged outside the oil pipe, a centralizer is arranged between the oil pipe and the sleeve, the bottom of the oil pipe is connected with a screening pipe, the tail end of the screening pipe is connected with a vibrator, the anode is arranged on the sleeve and connected with the positive electrode of the direct current power supply, and the negative electrode of the direct current power supply is connected with the sleeve and the oil pipe.
Description
Technical field
The utility model relates to a kind of extracting device of oil, is specifically related to a kind of oil well casing extracting device of oil.
Background technology
In oil extraction in oil field field, along with the continuous prolongation of production time after bringing in, oil well casing is corroded owing to touching corrosive medium around, cause casing wall attenuation, cause remitted its fury, thereby produce the phenomenons such as perforation, fracture, distortion, can say that corrosion is a main cause that causes casing failure.Casing corrosion perforation, will occur that multiple spot is run-down, and corrosion can be accelerated fatigue and then premature deformations and the damage of sleeve pipe.Casing corrosion leaks outside and not only causes oil well normally not produce, and causes economically huge loss, and has caused huge waste and serious environment pollution.In addition in oil recovery process because reasons in structure exists plugging removal effect poor, and then affect oil recovery efficiency.
Utility model content
The utility model object is to provide a kind of oil well casing extracting device of oil, can not only reduce casing corrosion, and can prevent from stopping up.
To achieve these goals, the utility model adopts following scheme:
A kind of oil well casing extracting device of oil, comprise oil pipe, sleeve pipe, dc source and anode, the outside of oil pipe is provided with sleeve pipe, between oil pipe and sleeve pipe, be provided with centralizer, the bottom of oil pipe connects screen casing, the end of screen casing connects vibrator, and anode is arranged on sleeve pipe DC power anode jointed anode, DC power cathode splicing sleeve and oil pipe.
Further, oil pipe lower, outer perimeter is provided with locker.
Further, oil pipe upper end is connected with insulation sleeve.
The beneficial effects of the utility model:
Be provided with anode and power supply, make the abundant cathodic polarization of oil well casing, can reduce casing corrosion, be provided with vibrator and can prevent from overlapping blockage.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure 1, sleeve pipe, 2, centralizer, 3, oil pipe, 4, locker, 5, screen casing, 6, vibrator, 7, dc source, 8, anode, 9, insulation sleeve.
The specific embodiment
Better understand the utility model for the ease of those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further details, following is only the exemplary protection domain of the present utility model that do not limit.
With reference to accompanying drawing 1, a kind of oil well casing extracting device of oil, comprise oil pipe 3, sleeve pipe 1, dc source 7 and anode 8, the outside of oil pipe 3 is provided with sleeve pipe 1, between oil pipe 3 and sleeve pipe 1, be provided with centralizer 2, the bottom of oil pipe 3 connects screen casing 5, and the end of screen casing 5 connects vibrator 6, anode 8 is arranged on the anodal jointed anode 8 of sleeve pipe 1 dc source 7, dc source 7 negative pole splicing sleeves 1 and oil pipe 3.
In the present embodiment, oil pipe 3 lower, outer perimeter are provided with locker 4.
In the present embodiment, oil pipe 3 upper ends are connected with insulation sleeve 9.
Below only described basic principle of the present utility model and preferred embodiment, those skilled in the art can make many changes and improvements according to foregoing description, and these changes and improvements should belong to protection domain of the present utility model.
