Description
Technical field
The utility model relates to the downhole tool of petroleum industry submerged electric oil pump well, spy is a kind of submersible electric pump hanging basket, connection
In the lower section of electric submersible pump unit, it can prevent lost circulation from entering oil reservoir again under the premise of can accept junk, to oil
Layer plays a protective role.
Background technique
When the daily production of submerged electric oil pump well, the cable of submersible electric pump needs strain relief clamp or steel band to be fixed on oil pipe, electricity
Cable clamp or steel band influenced due to liquid flow impact, aging etc. it is easy to fall off fall into well, will cause down-hole accident when serious, because
This needs to accept junk in unit lower part installation hanging basket.On the other hand, the submersible electric pump in electric pump well operates for a long time recovers the oil by force,
So that formation depletion is serious, when well-flushing, can not often establish circulation, can not resume production and the well that causes to lie, while lost circulation
Into stratum, oil layer pollution but will be caused.
To solve the above-mentioned problems, CN201420618991.5 discloses a kind of lost circulation prevention flushing packer, although can rise
To lost circulation prevention well-flushing function, but junk can not be accepted, and the work that submerged electric oil pump well hanging basket does not prevent well-flushing from missing at present
With.Therefore a kind of simple possible, strong operability are needed, does not increase the electric pump well that can prevent well-flushing from missing of risk in well
Special hanging basket.
Summary of the invention
The purpose of the utility model is to provide a kind of submersible electric pump hanging basket, have the function of accepting junk during normal production,
The smooth row of returning that can guarantee flushing fluid when needing to carry out well-flushing, avoids leakage from entering stratum, promotes well washing effect, avoids latent oil
Electric pump well is lain well, and production cost is reduced, and protects oil reservoir.
The technical solution of the utility model is: a kind of submersible electric pump hanging basket includes basket body and central tube, above basket body
Equipped with liquid flow hole, the tube body of box cupling is equipped with liquid flow hole, and the top of central tube is connect with box cupling, lower part is passed through from the bottom of basket body
And welded in through part and basket body, the lower end of basket body lower central pipe is connect with ball-and-seat, between basket body and ball-and-seat in
Heart tube outside is equipped with cup packer.
Compared with prior art, the remarkable result of the utility model is: being distributed liquid stream on the box cupling ontology of the utility model
Hole is connected with central tube；Basket body top is equipped with liquid flow hole, is convenient for drain, lower part closing, and central tube is passed through and welded from basket body bottom
It is connected together, the sundries such as junk, oil sludge and sand can be accepted in the annular space of basket body and central tube.Cup packer is at least at center
The outer installation one of pipe can be with Seal Oil lantern ring under well-flushing pressure difference using heatproof, the oil resistant rubber structure for installing metallic framework additional
It is empty.
Submerged electric oil pump well during normal production, well liquid from ball-and-seat enter, through the central tube in cup packer, basket body into
The top for entering the present apparatus, the annular space of oil pipe and casing is entered from the liquid flow hole of box cupling, and basket body can accept electric pump clamp or steel
Band.When reacting cycle well-flushing, flushing fluid enters central tube from the annular space of oil pipe and casing to downlink, by the liquid flow hole of box cupling
When, since the ball-and-seat of present apparatus lower part closes down going channel, flushing fluid can not downlink, while under the action of flushing fluid,
Cup packer spreading, encloses oil jacket annulus.Flushing fluid is forced to change direction, enters from the separator of submersible electric pump, from life
It produces tubing string and returns to ground, achieved the purpose that well-flushing lost circulation prevention.Present apparatus structure is simple, strong operability, can effectively accept and fall
Object avoids pit shaft accident, while can realize lost circulation prevention well-flushing.Submerged electric oil pump well Ka Jing can effectively be administered and well of lying, subtracted
Few workover treatment by Ka Jing and well initiation of lying, reduces production cost, has preferable application effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing, not limits the protection scope of the utility model.It is as described below to be only
The preferred embodiment of the utility model, other use the equivalence changes of the utility model, should belong to the protection of the utility model
Range.
Referring to Fig. 1, a kind of submersible electric pump hanging basket includes basket body 3 and central tube 2, and basket body 3 is equipped with liquid flow hole above.Box cupling 1
Tube body be equipped with liquid flow hole, the top of central tube 2 is connect with box cupling 1, lower part is passed through from the bottom of basket body 3 and in through part and
Basket body 3 is welded, and the lower end of 3 lower central pipe 2 of basket body is connect with ball-and-seat 5, outside the central tube 2 between basket body 3 and ball-and-seat 5
