Abstract
An electric submerged plunger oil pumping unit of the utility model main solves the problem of big investment, increased cost of oil production, and big treatment difficulty of the existing oil-well pump. The utility model is characterized in that the inside of the pump barrel on the upper end head of a plunger oil pumping unit (1) is arranged with a valve seat (6) whose axial bore (8) is arranged with a valve ball (7). The lower end of the plunger oil pumping unit (1) is ordinally connected with a screen casing (2) and a linear motor (3). The axle (9) of the linear motor (3) connects with a plunger (10) of the pump (1). The linear motor (3) connects with the inner power of a control cabinet (5) via a conducting wire (4). The electric submerged plunger oil pumping unit which is easy to operate, economizes the investment, and lowers the cost of oil production.
Description
Technical field:
The utility model relates to the used oil well pump in oil recovery field, oil field, particularly the latent plunger oil-well pump of electricity.
Background technique:
In oil recovery field, oil field, mechanical oil recovery is mainly used rod pumping pump, screw pump, submersible electric pump, and oil well pump is equipped with pumping unit on ground, be connected by sucker rod between pumping unit and the pump, so just strengthened investment, cost for oil production is increased, and maintenance load has been big; Screw pump need be equipped with power plant on ground, is connected by sucker rod between power plant and the pump, also has the problem that investment is big, cost for oil production is high and maintenance load is big; Submersible electric pump exists complex structure and the big problem of difficulty of processing, is unfavorable for oil field oil recovery development.
The model utility content:
In order to overcome the deficiency that existing oil well pump investment is big, cost for oil production is high and difficulty of processing is big, the utility model provides a kind of electricity plunger oil-well pump of diving, the characteristics that this pump has the investment of saving, reduction cost for oil production and is easy to construct.
The technical solution of the utility model is: this electricity dive plunger oil-well pump comprise linear electric motor, in the coupled screen casing of oil well pump and lower end of plunger is arranged, the pump barrel of plunger oil-well pump upper tip is built-in with valve seat, be equipped with valve ball on the axial bore of valve seat, the plunger oil-well pump lower end is connected with screen casing and linear electric motor successively, the linear electric motor axle links to each other with the plunger of pump, and linear electric motor link to each other with power supply in the control cabinet by lead.
The beneficial effect that the utlity model has is: this electricity is dived plunger oil-well pump owing to the pump barrel at the pump upper tip is built-in with valve, be connected with the linear electric motor that axle links to each other with plunger in the pump lower end, the plunger that drives pump by the linear electric motor axle moves up and down, reach the oil recovery lifting, and pumping unit and power plant need be set on ground, and also just need not sucker rod, simple in structurely be easy to construction, thereby solved the problem that investment is big, cost for oil production is high and difficulty of processing is big, effectively reduced cost for oil production.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-oil well pump among Fig. 1,2-screen casing, 3-linear electric motor, 4-lead, 5-control cabinet, 6-valve seat, 7-hole, 8-valve ball, 9-axle, 10-plunger.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, a kind of electricity dive plunger oil-well pump comprise linear electric motor 3, in the coupled screen casing 2 of oil well pump 1 and lower end of plunger 10 is arranged, the pump barrel of plunger oil-well pump 1 upper tip is built-in with valve seat 6, be equipped with valve ball 8 on the axial bore 7 of valve seat 6, plunger oil-well pump 1 lower end is connected with screen casing 2 and linear electric motor 3 successively, 39 of linear electric motor link to each other with the plunger 10 of pump 1, and linear electric motor 3 link to each other with power supplys in the control cabinet 5 by lead 4.
During actual the use, oil well pump 1 upper end is linked to each other with oil pipe, linear electric motor 3 link to each other with power supply in the ground control cabinet 5 by lead 4, after serving electricity for linear electric motor 3, the axle 9 of linear electric motor 3 drives plunger 10 and moves up and down, thereby reaches the purpose of oil well pump oil pumping, when plunger 10 moves down, valve ball 8 is closed, and the space that plunger 10 is abdicated forms a low-pressure cavity, and liquid enters pump barrel through plunger 10; When plunger 10 moves up, plunger 10 promotes liquid and backs down valve ball 8, liquid is discharged pump barrel, finish lifting, need not on ground pumping unit and power plant to be set, also need not sucker rod, simple in structure being easy to constructed, thereby solved the problem that investment is big, cost for oil production is high and difficulty of processing is big, effectively reduced cost for oil production.
Claims (1)
1, the latent plunger oil-well pump of a kind of electricity, comprise linear electric motor (3), in the coupled screen casing (2) of oil well pump (1) and lower end of plunger (10) is arranged, it is characterized in that: the pump barrel of plunger oil-well pump (1) upper tip is built-in with valve seat (6), be equipped with valve ball (7) on the axial bore (8) of valve seat (6), plunger oil-well pump (1) lower end is connected with screen casing (2) and linear electric motor (3) successively, linear electric motor (3) axles (9) link to each other with the plunger (10) of pump (1), and linear electric motor (3) link to each other with the interior power supply of control cabinet (5) by lead (4).
