Abstract
The invention discloses an extension structure of a lead-out line of a submersible linear motor, and a transport, fixing, use and mounting method. The method comprises the steps of reversely bending and folding back the 9.5-10.5m lead-out line of the submersible linear motor to be parallel to a submersible linear motor body, attaching the lead-out line to a housing of the submersible linear motor, mounting and buckling a shield on the external surface of the lead-out line attached to the housing, and fixing the shield and the lead-out line on the housing of the submersible linear motor with locking steel belts to avoid damage of the lead-out line due to rotation dislocation of the shield during transport. During underground mounting, the shield on the housing of the submersible linear motor is dismounted, the lead-out line traverses the outside of an oil well pump and is connected with a power cable, i.e. a connection point traverses the oil well pump, and then the shield is buckled and mounted on the lead-out line outside an oil well pump body and tightened and fixed by penetrating through holes in the shield with the locking steel belts to fully protect the lead-out line to avoid clash during operation.
Description
Technical field
The invention belongs to a kind of lead-out wire of oil immersion line motor, particularly a kind of oil immersion line motor lead-out wire extending structure and transport are fixed, are used installation method.
Background technology
At present, the oil recovery machiner that domestic and international oil recovery generally adopts oil pumper, sucker rod and oil well pump to form, it is large to there is volume in existing oil recovery machiner, cost is high, reactive loss is large, the shortcoming such as easily break down, Chinese invention patent " reciprocating submersible electric pump " (Chinese invention patent number: ZL 2,004 1 0050431.5) changes the artificial lifting way of oil extraction for this reason, there is the features such as simple, energy-saving and cost-reducing, easy to operate, the online tune ginseng of structure, the sucker rod thoroughly solving domestic and international long-standing problem mechanical oil recovery take off, the difficult problem of disconnected and side-abrasion of rod string.This product is alternative original oil production method not only, is also highly suitable for the exploitation of horizontal well, directional well, low permeability pay well.But from the situation of application at present, the lead-out wire of only about 1 meter need be left when oil immersion line motor dispatches from the factory, to be connected with power cable at operation field of going into the well.When operation field connects, the tie point of lead-out wire and power cable adopts insulating tape to be wound around, this tie point is on the oil well pump body of oil immersion line motor upper end, oil well pump body is provided with feed liquor screen casing, therefore the annular space liquid fluidity around pump body is larger, at down-hole high temperature, high pressure, under the environment of high corrosion, the insulating tape well liquid that flowed washes away for a long time, time one is long, insulating tape is invaded endlessly by fresh corrosive liquid and causes insulating tape failure of insulation, ground cannot be oil immersion line motor transmission of electric energy, thus cause oil immersion line motor cannot normally to have worked well operations, affect its useful life.
Summary of the invention
The object of this invention is to provide a kind of oil immersion line motor lead-out wire extending structure and transport fixing, use installation method, the well liquid that elimination is in contact flow on oil well pump larger due to oil immersion line motor lead-out wire and power cable tie point washes away, and the fault accelerated to cause failure of insulation to the corrosion of insulating tape and cannot work, transportation safety simultaneously, improves the service life of whole system.
A kind of oil immersion line motor lead-out wire extending structure provided by the invention: comprise oil immersion line motor casing and be positioned at the linear electric motors lead-out wire outside oil immersion line motor casing, it is characterized in that: oil immersion line motor lead-out wire is 9.5-10.5 meters.
Oil immersion line motor lead-out wire transport provided by the invention is fixing, use installation method:
First the lead-out wire back-flexing of oil immersion line motor 9.5-10.5 meters is turned back parallel with oil immersion line motor body, and be attached on oil immersion line motor casing; Guard shield dress is buckled in the lead-out wire outer surface be attached on casing; Be fixed on oil immersion line motor casing with locking steel band by guard shield and lead-out wire, the two ends of guard shield are fastened on oil immersion line motor two ends by set bolt, prevent guard shield in transport from rotating dislocation damaging leading-out wire.
When lower well operations is installed; pull down the guard shield on oil immersion line motor casing; lead-out wire is crossed oil well pump outside to be connected with power cable; namely tie point crosses oil well pump; then by guard shield spiral-lock on this external lead-out wire of oil well pump; and tightened fixing with locking steel band through the perforation on guard shield, by lead-out wire protection completely, avoid in operation by clashing and breaking.
Good effect of the present invention is:
After oil immersion line motor lead-out wire extends to about 10 meters, the tie point of oil immersion line motor lead-out wire and power cable has crossed the oil well pump feed liquor screen casing position of oil immersion line motor upper end, away from the dynamic environment of well liquid flowing, tie point is in the static static environment of well liquid, thus avoid the dynamic environment that tie point flows at well liquid, accelerate to cause failure of insulation to the corrosion of insulating tape and the fault that cannot work.Improve the service life of whole system.
Meanwhile, the overlength state of oil immersion line motor lead-out wire more than more than 1 meter is solved, the problem that cannot transport safely; Guard shield realizes twice application.
accompanying drawing illustrates:
Fig. 1 is that oil immersion line motor arranges overlength lead-out wire and transport stationary state figure.
Fig. 2 is sheath schematic shapes.
Fig. 3 is A-A cutaway view of Fig. 2.
Fig. 4 is oil immersion line motor lead-out wire is fixed on oil well pump schematic diagram in down-hole.
Fig. 5 is B-B cutaway view of Fig. 4.
Embodiment
See Fig. 1-3, lead-out wire 1 length that oil immersion line motor 4 is positioned at outside casing is 9.5-10.5 meters.
The transport of oil immersion line motor lead-out wire is fixing:
Lead-out wire 1 back-flexing long for oil immersion line motor 9.5-10.5 meters is turned back parallel with oil immersion line motor body, and is attached on oil immersion line motor 4 casing; Guard shield 2 is filled and buckles and lead-out wire 1 outer surface be attached on casing; With the known conventional locking part of locking steel band 3() guard shield 2 and lead-out wire 1 are fixed on the casing of oil immersion line motor 4, the two ends of guard shield 2 are connected on linear electric motors two ends connection coupling 7 by set bolt 6, make it into and be integrated, stop, in transport, dislocation is rotated to lead-out wire 1 and cause damage; Guard shield 2 is elongated slot structure, biside plate has multiple perforation 2-1 installing locking steel band 3, is fixedly connected with more firm when considering to go into the well with oil well pump body simultaneously, in order to adapt to oil well pump body exterior shape, biside plate arranging multistage and protrudes and recess.
Install at lower well operations:
See Fig. 4,5; pull down the guard shield 2 on oil immersion line motor casing; oil immersion line motor 4 and oil well pump 5 are connected by prior art; and lead-out wire 1 is crossed oil well pump 5 outside be connected with power cable; namely tie point crosses oil well pump 5, then by guard shield 2 spiral-lock on this external lead-out wire 1 of oil well pump, and tightened fixing with the locking steel band 3 perforation 2-1 passed on guard shield 2; by lead-out wire protection completely, avoid in operation by clashing and breaking.See Fig. 5, guard shield 2 spiral-lock, between two righting ribs 8 when oil well pump is originally external.
