Abstract
An antisepsis anti-scale device specially used by an electric submersible pump mainly solves the problem that the antisepsis anti-scale to the whole electric submersible pump can not implemented in the current electric submersible pump set antisepsis anti-scale technology. The utility model is characterized in that an external shell (3) and an internal sleeve (4) with a screen hole (6) at the lower end are arranged between an upper joint (1) with a through hole (2) and a lower joint (7); the internal sleeve (4) is arranged in the external shell (3); an annular cavity formed by the external shell (3) and the internal sleeve (4) is internally provided with a corrosion inhibitor (5). The utility model is characterized by implementing the antisepsis anti-scale to the whole electric submersible pump, low antisepsis cost and good antisepsis effect.
Description
Technical field:
The utility model relates to a kind of anti-corrosion anti-scale device that is applied to lifting machinery in the oil recovery field, oil field, especially a kind of submersible electric pump special anti-corrosion scale-proof apparatus that is applied to Electric Submersible Pump Unit.
Background technique:
In oil recovery field, oil field, Electric Submersible Pump Unit is considered to a kind of both economical effective oil production method, can extract formation fluid from the oil well of darker different situations in a large number.The submersible electric pump system is made of motor, cable, protector, gas separator, multistage sinking centrifugal pump etc.; the said equipment all wants long period of soaking in well liquid when this system carries out work, and it is very important therefore these equipment being carried out the anti-corrosion anti-scale protection.Existing electronic oil recovery centrifugal pump unit anti-corrosion anti-scale technology all is to be coated with an alloy-layer or a certain anticorrosive paint on the shell of centrifugal pump and motor usually; the defective of this way is to protect positions such as the housing of electric pump unit, joint, and can not bring into play protective action for other constituent element of pump assembly.
The model utility content:
Can not carry out deficiency effectively anticorrosion, antiscale to whole Electric Submersible Pump Unit in order to overcome the alloy-plated layer that adopts in the existing Electric Submersible Pump Unit anti-corrosion anti-scale technology or the method for coating; the utility model provides a kind of submersible electric pump special anti-corrosion scale-proof apparatus that is applied to Electric Submersible Pump Unit; this kind submersible electric pump special anti-corrosion scale-proof apparatus has and can carry out anti-corrosion anti-scale protection, anti-corrosion anti-scale good effectiveness to whole Electric Submersible Pump Unit.
The technical solution of the utility model is: this kind submersible electric pump special anti-corrosion scale-proof apparatus, comprise that the upper connection, lower contact, frame and the lower end that have through hole have the inner sleeve of sieve aperture, frame and inner sleeve are fixed between upper connection and the lower contact, inner sleeve places among the frame, in the toroidal cavity that frame and inner sleeve form corrosion inhibitor is arranged.
The upper connection upper end has outside thread, so that and motor connection.
The lower contact lower end has internal thread, so that connect Wel packing.
The utlity model has following beneficial effect: because the submersible electric pump special anti-corrosion scale-proof apparatus in the such scheme is fixed under the motor when practical application; the corrosion inhibitor that is placed in the anti-corrosion anti-scale device is evenly discharged under the souring of well liquid lentamente; the corrosion inhibitor that discharges in the anti-corrosion anti-scale device makes whole submersible electric pump system all be immersed in the well liquid that contains corrosion inhibitor; from the nethermost motor of electric pump unit to centrifugal pump; cable all is protected; thereby it is effectively anticorrosion to make that whole Electric Submersible Pump Unit all is in; among the antiscale protection; can carry out anticorrosion to whole Electric Submersible Pump Unit so the utlity model has; the antiscale protection, the characteristics of favorable anti-corrosion effect.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model;
1-upper connection among the figure, 2-through hole, 3-frame, 4-inner sleeve, 5-corrosion inhibitor, 6-sieve aperture, 7-lower contact.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in FIG., submersible electric pump special anti-corrosion scale-proof apparatus described in the utility model, mainly the inner sleeve 4 that has a sieve aperture 6 by the upper connection 1 that has through hole 2, lower contact 7, frame 3 and lower end is formed, frame 3 and inner sleeve 4 are fixed between upper connection 1 and the lower contact 7, inner sleeve 4 places among the frame 3, in the toroidal cavity that frame and inner sleeve form corrosion inhibitor 5 is arranged.
Upper connection 1 upper end has so that the outside thread that is connected with motor, and lower end and frame 3 and inner sleeve 4 link, and the Placement between them can adopt by adding the sealing of screw thread glue after being threaded also can adopt welding.Lower contact 7 lower ends have internal thread, so that be connected with Wel packing, lower contact 7 and the connecting mode of frame 3 and inner sleeve 4 equally also can adopt and be threaded or weld.
When practical application, anti-corrosion anti-scale device described in the utility model is fixed in the below of motor, and well liquid enters the inner chamber that is formed by inner sleeve by separator, and meanwhile corrosion inhibitor 5 slowly is released from sieve aperture, mixes with the well liquid phase then.The well liquid of band corrosion inhibitor flows out from the through hole of upper connection under the lifting force effect of multistage centrifugal pump, passes through motor, protector, enters after the centrifugal pump supercharging from separator and gives rise to ground by oil pipe.This shows that in whole lifting process the corrosion inhibitor whole Electric Submersible Pump Unit of having flowed through makes Electric Submersible Pump Unit obtain protection on the whole.
Claims (3)
