Abstract
The utility model discloses a combined production-separating pump of a rod pump and an electric submersible pump, relates to oil-production equipment and solves the problems of short workover-free period of the oil well and high investment cost caused by the defects of the technique in the original production-separating equipment; in the combined production-separating pump of the rod pump and the electric submersible pump, the rod pump is arranged on the upper part of an oil pipe, at the central part of which a packer is arranged; a bridge-type channel is arranged in the oil pipe and the electric submersible pump is arranged on the lower part of the oil pipe; and a sealed cable bond is connected with the electric submersible pump. The utility model adopts the structure and can guarantee that the oil production can be carried out under two pressure systems simultaneously, thus not only guaranteeing the oil yield of a low-pressure low-yield oil layer, but also guaranteeing the oil yield of a high-pressure high-yield oil layer without influence between the two layers, improving the yield, being beneficial to the maintenance of the oil well, prolonging the workover-free period and further reducing the investment cost.
Description
Technical field: the utility model relates to a kind of oil field oil production equipment, is a kind of combined type separate extracting pump specifically.
Background technique: in the oilfield recovery process, because the pressure between oil reservoir there are differences, need exploit respectively at the high pressure zone and the low pressure layer of oil reservoir, the existing branch mode of adopting has the monomer separate extracting pump, join and adopt the device branch and adopt etc., though the above-mentioned branch mode of adopting can reach the effect that branch is adopted, but because technologic defective, under the interference of oil reservoir pressure reduction producing fluid level, the high pressure oil reservoir influences low pressure reservoir, is unfavorable for the maintenance of oil well, cause oil well repair free period short, improve cost of investment.
Summary of the invention: in order to solve the problem of above-mentioned existence, the utility model provides a kind of assurance high low pressure oil reservoir to work simultaneously, and the sucker rod pump and the electric submersible pump that are independent of each other meet separate extracting pump; The purpose of this utility model is achieved through the following technical solutions: the compound separate extracting pump of sucker rod pump and electric submersible pump, on oil pipe top sucker rod pump is installed, at the oil pipe middle part packet is installed, in oil pipe, be provided with passageway bridge, in the oil pipe bottom electric submersible pump is installed, sealing cable junctions is connected with electric submersible pump.
The beneficial effects of the utility model: the utility model adopts said structure, sucker rod pump and electric submersible pump are linked together by packet, sucker rod pump suction packet supernatant liquid, in oil pipe, be discharged to outside the well, electric submersible pump suction packet lower floor liquid, liquid by passageway bridge outside oil sets annular space is discharged well, the compound separate extracting pump of the utility model can guarantee to recover the oil respectively under two pressure systems simultaneously, both guaranteed the output of low-voltage and low-yield oil reservoir, and guaranteed the output of high pressure high capacity reservoir again, two oil reservoirs are independent of each other, improve output, help the maintenance of oil well, prolong being excused from a college course the phase of oil well, and then reduce cost of investment.
Description of drawings:
Fig. 1 is the structural representation of sucker rod pump and the compound separate extracting pump of electric submersible pump.
Embodiment: the compound separate extracting pump of sucker rod pump and electric submersible pump, on oil pipe 1 top sucker rod pump 2 is installed, at oil pipe 1 middle part packet 4,5 is installed, packet 4,5 is the gravity packet, the two end part of packet 4 are fixed on the oil pipe 1 by box cupling 11, box cupling 12, the two end part of packet 5 are fixed on the oil pipe 1 by box cupling 3, box cupling 13, the inside of oil pipe 1 is provided with passageway bridge 6, in oil pipe 1 bottom electric submersible pump 7 is installed, sealing cable junctions 8 is connected with electric submersible pump 7, the bottom of electric submersible pump 7 is connected with floral tube 9, and floral tube 9 ends are equipped with plug 10.
