Description

Technical Field

[0001] This utility model belongs to the field of submersible electric pump technology, specifically relating to a corrosion-resistant and scale-resistant submersible electric pump for oil extraction. Background Technology

[0002] An electric submersible centrifugal pump (referred to as an electric submersible pump) is a multi-stage centrifugal pump that works downhole. It is a type of oil production equipment in which the centrifugal pump and submersible motor are lowered into the well through an oil pipe. The motor drives the multi-stage centrifugal pump to rotate and generate centrifugal force, which lifts the crude oil in the well to the surface. It is a widely used rodless pump oil production equipment in various oil fields.

[0003] When a submersible electric pump is fixed at the wellhead, a base is needed for support. In the prior art, Chinese utility model patent with authorization announcement number CN220816024U discloses "a submersible electric pump base", which includes a base and an oil well. The submersible electric pump is installed on the top of the base. Fixed piles are installed at both ends of the base. A pressure gauge is installed on the top of the submersible electric pump. A cable is installed on the left side of the top of the submersible electric pump. A controller is installed at the end of the cable away from the submersible electric pump. An oil drain valve is installed on the right side of the top of the submersible electric pump, and an oil delivery pipe is installed at the end of the oil drain valve away from the submersible electric pump.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 The present invention provides the following technical solution: a corrosion-resistant and scale-resistant submersible electric pump for oil extraction, comprising a submersible electric pump body 1 and a support base 2, wherein the submersible electric pump body 1 passes through the support base 2, and the support base 2 is fixed to the wellhead for supporting the submersible electric pump body 1, and further comprising: a fixing hoop 3, an inclined support rod 4, a movable seat 5 and a drive mechanism 6.

[0020] Furthermore, by Figure 1 and Figure 2 As shown in this embodiment, the fixing hoop 3 is fixed to the submersible pump body 1, the two inclined support rods 4 are symmetrically distributed, and the top of the inclined support rod 4 is rotatably connected to the fixing hoop 3.

The support base 2 is fixed to the wellhead by conventional means to support the submersible pump body 1. When necessary, the driving mechanism 6 is activated to drive the moving seat 5 to move in the horizontal direction. The moving seat 5 drives the inclined support rod 4 to flip and move, and the inclined support rod 4 drives the submersible pump body 1 to rise and fall, thereby adjusting the submersible pump body 1 to meet different working needs and improve the discharge efficiency and system efficiency.

[0021] It should be noted that the main body 1 of the submersible electric pump is a very common piece of equipment in oil extraction. Its working principle and internal structure are existing technologies that have been fully disclosed, and will not be elaborated on further in this article.

[0022] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the drive mechanism 6 includes: a fixed plate 61, a threaded rod 62, and a drive motor 63.

[0027] Optionally, by Figures 1-3 As shown in this embodiment, bolt 10 penetrates the inclined support rod 4 to form a rotating structure, so that the inclined support rod 4 can rotate relative to the semi-circular hoop 31.

[0028] It should be noted that the aforementioned solution is only a preferred embodiment of this utility model and is not intended to limit this utility model. By using the No. 2 bolt 10 and No. 2 nut 11 to install the fixing hoop 3, a rotating structure is formed for the inclined support rod 4. This has the characteristics of convenient installation and easy disassembly and maintenance. In actual use, other conventional workpieces can also be used to form a rotating structure for the inclined support rod 4, such as hinges, pivots, rivets, etc.

[0030] It should be noted that the aforementioned solution is only a preferred embodiment of this utility model and is not intended to limit this utility model. The use of bolt No. 3 12 and nut No. 3 13 to form a rotating structure for the inclined support rod 4 has the characteristics of convenient installation and easy disassembly and maintenance. In actual use, other conventional workpieces can also be used to form a rotating structure for the inclined support rod 4, such as hinges, pivots, rivets, etc.

The moving seat 5 moves horizontally under the action of the threaded rotation. The moving seat 5 drives the inclined support rod 4 to flip and move. The inclined support rod 4 drives the submersible electric pump body 1 to rise and fall, thereby adjusting the submersion depth of the submersible electric pump body 1 to meet different working needs and improve displacement efficiency and system efficiency. The combination of the limiting flange 7, the No. 1 bolt 8, and the No. 1 nut 9 can further improve the stability of the submersible electric pump body 1, and rotating the No. 1 nut 9 can limit the adjustment range of the submersible electric pump body 1.
