Abstract
The utility model discloses a non-metallic pipe oil-submersible screw pump oil production plant, and aims to improve anticorrosion capacity of pipe strings and prolong production life. A wellhead hanger and an adapter are connected in a non-metallic pipe in a vulcanization mode. An oil draining machine, a screw pump, a coupling, a protector, a drive electromotor and a power cable which is connected with a ground controller are sequentially connected below the adapter. According to the non-metallic pipe oil-submersible screw pump oil production plant, the non-metallic pipe is used as a liquid conveying channel of the oil-submersible screw pump, and therefore the corrosion problem of well liquid to a metallic pipe can be well solved, and the underground working life of the pipe strings is prolonged. The tensile and internal pressure strength requirements can be guaranteed through the non-metallic pipe, continuous operation tripping in and pulling out can be achieved, and labor intensity of operators is greatly relieved. A good means is provided for changing the structure of the underground production pipe strings through the vulcanization connection of the non-metallic pipe and the wellhead hanger.
Description
Technical field
The utility model relates to a kind of nonmetallic pipe submersible screw pump oil extraction device, belongs to mechanical oil recovery technical field.
Background technique
At present, the main method of field produces is that pumping unit has bar oil recovery, downhole electrical motor rodless pumping operation and hydraulic drive oil recovery etc., and each method, except carrying the mode difference of liquid energy, all carries liquid to ground by metal oil conduit.During metal oil conduit operation, need single connection, construction operation amount is large, and personnel's operation intensity is high, long construction period.In addition, metal oil conduit is subject to the corrosion of down-hole liquid, thus reduction of service life.
Summary of the invention
The purpose of this utility model is to provide a kind of nonmetallic pipe submersible screw pump oil extraction device, to improve the antiseptic power of tubing string, extends Production Life.
Concrete technology contents of the present utility model is as follows:
The nonmetallic pipe inner top of this device connects well mouth hanger by vulcanization, and well mouth hanger top is provided with the Sealing of sealing oil jacket annular space; In nonmetallic pipe, pass through vulcanization coupling adapter downwards; crossover sub lower end connects oil drainer; oil drainer lower end connecting screw rod pump; screw pump lower end connects coupling; coupling lower end connection protector; protector lower end connects drive motor, the drive motor power cable that is tightly connected, and power cable top connects ground controller.
This device utilizes nonmetallic pipe as the liquid supplying passage of screw submerged pump, can solve preferably the etching problem of well liquid to metal tube, extends the underground work life-span of tubing string.Nonmetallic pipe can guarantee tension, anti-interior requirement of strength of pressing, and can be lowered to continuously and trip out operation, significantly reduces operating personnel's labor intensity.The structure that the sulfuration of nonmetallic pipe and well mouth hanger is connected to change downhole production tubing string provides good means.
Accompanying drawing explanation
Fig. 1 is nonmetallic pipe submersible screw pump oil extraction device structural representation.
Embodiment
Embodiment:
With reference to Fig. 1, embodiment of the present utility model is further illustrated:
This device mainly comprises ground controller 1, well mouth hanger 2, nonmetallic pipe 3, crossover sub 4, oil drainer 5, screw pump 6, coupling 7, protector 8, drive motor 9 and power cable 10;
Nonmetallic pipe 3 inner tops connect well mouth hanger 2 by vulcanization, and well mouth hanger 2 tops are provided with the Sealing of sealing oil jacket annular space.Nonmetallic pipe 3 is interior downwards by vulcanization coupling adapter 4; the crossover sub 4 lower ends oil drainer 5 that is threaded; the oil drainer 5 lower ends screw pump 6 that is threaded; the screw pump 6 lower ends coupling 7 that is threaded; the coupling 7 lower ends protector 8 that is threaded; the protector 8 lower ends drive motor 9 that is threaded, drive motor 9 power cable 10 that is tightly connected, power cable 10 tops connect ground controllers 1.
Nonmetallic pipe 3 is made by composite material, maximum diameter can reach 50mm, the join strength of itself and well mouth hanger 2 reaches self and well mouth hanger 2 and enters the twice of well tool gross weight of equipment amount, flexible, can coil construction operation on cylinder, in anti-, pressure and tensile strength are higher, and anti-antiseptic power is strong, can guarantee underground construction safety.
During the operation of this device, electric current and the magnitude of voltage of input, output are tested and shown to ground controller 1, and control drive motor 9 operations.Enter before well, close oil drainer 5, while playing well, drop into rod whip and open oil drainer 5.Screw pump 6, coupling 7, protector 8 and drive motor 9 form down-hole rodless pumping operation device.8 pairs of coupling 7 of protector, drive motor 9 play balance pressure and prevent that well liquid from entering.Power cable 10 transmits electric energy to drive motor 9, and drive motor 9 drives coupling 7 and screw pump 6 rotations, and down-hole liquid is delivered to ground through nonmetallic pipe 3.
