Abstract
The utility model discloses a reciprocating oil extraction pump for the linear motion actuator oil-submersible, comprising a linear motion actuator provided in the oil conduit, and a reciprocating plunger pump, wherein the primary linear motion actuator is provided in the oil conduit, the secondary linear motion actuator is provided on a hollow shaft, the hollow shaft lower end is connected with the plunger pump pole connected with a plunger piston, and the plunger pump is connected with the oil conduit. The utility model has the advantages of high efficiency, low energy consumption, simple structure, low costs and long service life, and can be used widely for the oil extraction process.
Description
One, technical field
The utility model relates to a kind of down-hole oil production system that is used for field produces, and the latent oil of particularly a kind of linear electric motor is oil extraction pump back and forth.
Two, background technique
Present domestic most wells adopts beam pumping unit to exploit, outfit plunger pump under this pumping well, this system maturation that possesses skills, the reliability advantages of higher, but its complex structure have a series of parts such as speed reducer, walking beam, crank, equilibrium block, sucker rod, and efficient is lower, topmost shortcoming influences crude output and spends a large amount of Repair Capital for causing the oil pipe eccentric wear easily.Present rodless pumping operation mainly adopts electric oil submerged screw pump, and the advantage of this technology is the efficient height, but also has the shortcoming that infusion of financial resources is high, energy input is big.
Three, summary of the invention
The utility model provides back and forth oil extraction pump of the latent oil of a kind of linear electric motor, can overcome the consistent eccentric wear phenomenon that exists of pumping unit oil well by this pump, and the energy input of reduction pumping unit improves oil pumping system efficient.
The latent oil of linear electric motor described in the utility model is oil extraction pump back and forth, comprise the linear electric motor that are installed in the oil pipe and coupled reciprocating pump, described linear electric motor are elementary to be installed in the oil pipe, secondary being installed on the hollow shaft, described hollow shaft lower end is connected with plunger pump rod on being connected in plunger, and plunger pump is connected with oil pipe.
Wherein, described linear electric motor primary and secondary all is installed on coil winding.Described plunger pump bottom is equipped with standing valve.Upper travelling valve and lower travelling valve are installed on the described plunger.
The utility model has following advantage compared with prior art:
Efficient wants high than beam pumping unit, and power savings is obvious, has saved the complex system on ground simultaneously, has reduced disposable input cost, and has thoroughly eliminated the eccentric wear phenomenon of pump and oil pipe, has prolonged pump detection period.
Four, description of drawings
Accompanying drawing is the utility model structural representation.
Five, embodiment
As shown in the figure, the latent oil of a kind of linear electric motor is oil extraction pump back and forth, comprise the linear electric motor that are installed in the oil pipe and coupled reciprocating pump, linear electric motor elementary 2 are installed in the oil pipe 1, secondary 3 are installed on the hollow shaft 13, hollow shaft 13 lower ends are connected with plunger pump rod 11 on being connected in plunger 10, and plunger pump 6 is connected with oil pipe 1.
Linear electric motor elementary 2 and secondary 3 all are installed on coil winding 4,14.Plunger pump 6 bottoms are equipped with standing valve 7.Upper travelling valve 9 and lower travelling valve 8 are installed on the plunger 10.Oil pipe 1 links to each other with plunger pump 6 by box cupling 5.Hollow shaft 13 is connected with plunger pump rod 11 by connecting box cupling 12.
When moving downward by secondary 3 of control system control linear electric motor, driving plunger pump rod 11 and plunger 10 moves downward together, this moment, upper travelling valve 9 and lower travelling valve 8 all were opened, standing valve 7 is in closed condition, and the liquid that enters in the plunger pump 6 enters in the pump plug pump rod 11 by upper travelling valve 9 and lower travelling valve 8.When secondary 3 of control system control linear electric motor move upward, driving plunger pump rod 11 and plunger 10 moves upward together, this moment, upper travelling valve 9 and lower travelling valve 8 were all closed, standing valve 7 is in open mode, enter liquid in the plunger pump rod 11 and be pressed in secondary 3 the hollow shaft 13, further enter in the oil pipe 1 and be moving upward.The interior pressure of plunger pump internal cavities this moment reduces.The liquid of down-hole enters the plunger pump internal cavities by standing valve 7, replenishes the liquid measure that is raised.
