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 extension knot
Structure and transport are fixed, use installation method.
Background technology
At present, recovered the oil the general oil recovery machiner constituted using oil pumper, sucker rod and oil well pump, existing oil recovery both at home and abroad
Machinery has that volume is big, and high cost, reactive loss is big, is that this Chinese invention patent is " reciprocating latent the shortcomings of be susceptible to failure
Oily electric pump "（Chinese invention patent number：ZL 2004 1 0050431.5）The artificial lifting way of oil extraction is changed, with structure
Simply, it is energy-saving, easy to operate, online to adjust the features such as joining, thoroughly solve the sucker rod of domestic and international long-standing problem mechanical oil recovery
De-, disconnected and side-abrasion of rod string problem.The product not only alternative original oil production method, is also highly adaptable for horizontal well, orientation
The exploitation of well, low permeability pay well.But from the point of view of the situation of current application, an only 1 meter left side need to be left when oil immersion line motor dispatches from the factory
Right lead-out wire, to be connected with power cable in operation field of going into the well.When operation field is connected, lead-out wire and power cable
Tie point wound using insulating tape, the tie point is on the oil well pump body of oil immersion line motor upper end, oil well pump sheet
Body is provided with feed liquor screen casing, therefore annular space liquid fluidity around pump body is larger, high temperature, high pressure, height in underground
In the environment of corrosion, insulating tape is washed away for a long time by flowing well liquid, and the time one is grown, insulating tape by fresh corrosive liquid in a steady stream not
Disconnected intrusion and cause insulating tape failure of insulation, ground will be unable to be oil immersion line motor conveying electric energy, so as to cause latent oil
Linear electric motors cannot normal work rise well operations, influence its service life.
The content of the invention
Fixed it is an object of the invention to provide a kind of oil immersion line motor lead-out wire extending structure and transport, use installation side
Method, eliminates because oil immersion line motor lead-out wire and power cable tie point are in the larger well liquid of contact flow on oil well pump
Wash away, and accelerate the failure that the corrosion of insulating tape is caused failure of insulation and cannot be worked, while transportation safety, improves a whole set of
The service life of system.
A kind of oil immersion line motor lead-out wire extending structure that the present invention is provided：Including oil immersion line motor casing and it is located at
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.
The oil immersion line motor lead-out wire transport that the present invention is provided is fixed, uses installation method：
The lead-out wire back-flexing of 9.5-10.5 meters of oil immersion line motor is turned back flat with oil immersion line motor body first
OK, and it is attached on oil immersion line motor casing；Shield dress is buckled in the lead-out wire outer surface being attached on casing；With locking steel
Be fixed on oil immersion line motor casing for shield and lead-out wire by band, and the two ends of shield are fastened on latent oil by fixing bolt
Linear electric motors two ends, shield rotates dislocation damaging leading-out wire in preventing transport.
When lower well operations are installed, the shield on oil immersion line motor casing is pulled down, lead-out wire is crossed outside oil well pump
It is connected with power cable, i.e., tie point crosses oil well pump, then shield spiral-lock is used in combination on the external lead-out wire of oil well pump sheet
Locking steel band is tightened fixation through the perforation on shield, and lead-out wire is completely protected, it is to avoid clashing and breaking are received in operation.
The positive effect of the present invention is：
After oil immersion line motor lead-out wire extends to 10 meters or so, the connection of oil immersion line motor lead-out wire and power cable
Point 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
In the static environment that well liquid is static, thus the dynamic environment that tie point flows in well liquid is avoided, accelerated to insulating tape
The failure that corrosion causes failure of insulation and cannot work.Improve the service life of whole system.
Meanwhile, solve overlength state of the oil immersion line motor lead-out wire more than more than 1 meter, it is impossible to which that transports safely asks
Topic；Shield is realized applying twice.
Brief description of the drawings：
Fig. 1 is that oil immersion line motor sets overlength lead-out wire and transport stationary state figure.
Fig. 2 is sheath schematic shapes.
Fig. 3 is A-A sectional views of Fig. 2.
Fig. 4 is the schematic diagram that oil immersion line motor lead-out wire is fixed on oil well pump in underground.
Fig. 5 is B-B sectional views of Fig. 4.
Specific embodiment
See Fig. 1-3, the length of lead-out wire 1 that oil immersion line motor 4 is located at outside casing is 9.5-10.5 meters.
The transport of oil immersion line motor lead-out wire is fixed：
9.5-10.5 meters long of the back-flexing of lead-out wire 1 of oil immersion line motor is turned back flat with oil immersion line motor body
OK, and it is attached on the casing of oil immersion line motor 4；Shield 2 is filled the outer surface of lead-out wire 1 buckled and be attached on casing；With lock
Tight steel band 3（Known conventional locking part）Shield 2 and lead-out wire 1 are fixed on the casing of oil immersion line motor 4, shield 2
Two ends be connected on linear electric motors two ends connection coupling 7 by fixing bolt 6, make one, prevent transport in drawing
Outlet 1 rotates dislocation and causes to damage；Shield 2 is slot structure long, and multiple perforation 2-1 for installing locking steel band 3 are provided with biside plate,
Consider to be fixedly connected with oil well pump body when going into the well simultaneously it is more firm, in order to adapt to oil well pump body exterior shape, in biside plate
Upper setting multistage protrusion and recess.
Installed in lower well operations：
See Fig. 4,5, pull down the shield 2 on oil immersion line motor casing, by oil immersion line motor 4 with oil well pump 5 by existing
Technology is connected, and lead-out wire 1 is crossed into the outside of oil well pump 5 is connected with power cable, i.e., tie point crosses oil well pump 5, so
Afterwards by the spiral-lock of shield 2 on the external lead-out wire 1 of oil well pump sheet, and with locking steel band 3 through the perforation 2-1 on shield 2 by its
Fixation is tightened, lead-out wire is completely protected, it is to avoid clashing and breaking are received in operation.See Fig. 5, the spiral-lock of shield 2, when oil well pump sheet is external
Between two righting ribs 8.
