Embodiment Construction
[0022] Refer to attached figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 Make the invention. The intelligent reversing electric submersible rodless pumping device comprises a wellhead 3, a well pipe 4 and an oil pipe 5. The wellhead 3 is arranged on the top of the well pipe 4, and the oil pipe 5 is arranged in the well pipe 4. It is characterized in that: The lower end is provided with an inverted plunger pump 6, a reciprocating motion converter 7 and an oil submersible motor 8 in sequence. The oil submersible motor 8 is connected with the PLC control cabinet 1 through the oil submersible cable 2, and the operation of the oil submersible motor 8 is controlled by the PLC control cabinet 1. In operation, the inverted plunger pump 6 is controlled by the reciprocating converter 7 to lift the oil to the ground.
[0023] The inverted plunger pump 6 includes an oil pipe collar 61, an outer pipe 62, a pump barrel assembly 63, a plunge...

The invention discloses an intelligent reversing electric submersible rodless oil pumping device. The intelligent reversing electric submersible rodless oil pumping device comprises a well mouth, a well pipe and an oil pipe, wherein the well mouth is formed on the upper part of the well pipe; and the oil pipe is arranged in the well pipe. The intelligent reversing electric submersible rodless oil pumping device is characterized in that an inverse plunger pump, a reciprocating commutator and a submersible oil motor are sequentially arranged at the lower end of the oil pipe; and the submersible oil motor is connected with a programmable logic controller (PLC) control cabinet by a submersible oil cable. By the intelligent reversing electric submersible rodless oil pumping device, the submersible oil motor is controlled by a ground PLC technology to rotate; and the rotation movement of the submersible oil motor is converted into linear reciprocation movement by the reciprocating commutator, so that the plunger pump can be safely and reliably driven to move; the aim of raising crude oil from the underground to the ground is fulfilled; and the problems of high drive, eccentric wear of the oil rod and the oil pipe of a rod pump ground as well as a complicated control system and impact current of a linear submersible oil electric pump can be solved; and therefore, oil extraction can be quantitatively realized.
Description
[0001] technical field [0002] The invention relates to an oil pumping device for oil extraction, which is applied in the field of oil exploitation, in particular to an intelligent reversing electric submersible rodless oil pumping device. Background technique [0003] At present, the oil extraction machinery used in the oil field mainly includes: the oil pumping system driven by the ground pumping unit, and the oil pumping system driven by the submersible motor. The oil pumping system driven by the ground pumping unit is to use the ground pumping unit to drive the plunger pump to realize oil pumping. The biggest disadvantage of this oil pumping system is that the ground equipment is huge, it is not environmentally friendly, and it cannot solve the problem of eccentric wear of the sucker rod and the oil pipe. Contents of the invention [0004] The purpose of the present invention is to provide an intelligent reversing electric submersible that no longer uses huge ground ...
