At present, most common oil production method is extracting device of oil of the beam pumping unit with sucker rod, and this device is by walking beam Formula oil pumper, reduction box, motor (or motor+frequency conversion), wellhead assembly, down-hole oil tube, rigid sucker rod and oil well pump composition.Work As process rotated by motor, linear motion is converted rotational motion into by dynamic reduction box, belt pulley, double leval jib, drive is taken out Beam hanger and oil well pump pump in oil pipe completes oil pumping process.
Deficiency existing for this device has:, can only be in some length section of oil pipe 1. the haul distance of sucker rod is restricted Move back and forth, therefore, the easy wax deposition of tube inner wall, fouling, pit shaft wax removal and inhibition work amount is big, costly;2. beam-pumping unit is held By a kind of cycle alternate load with impact, detent torque is big, and this load request causes dragging motor power big, oil pumping During machine normal operation, light condition is in again, load factor is low, and electric efficiency is low;3. rigid sucker rod loading, unloading workload is big, and one Denier oil well pump, which breaks down, overhauls inconvenience.
Utility model content
Technical problem to be solved in the utility model is to be directed to above-mentioned deficiency of the prior art, there is provided one kind switch Reluctance motor one drag two extracting device of oil, whole system efficiency is improved, and long stroke is realized by flexible rod, effectively solve well Cylinder wax deposition, scale problems, and pump detection and workover is more convenient.
The utility model uses following technical scheme:
A kind of switched reluctance machines one drag two extracting device of oil, including switched reluctance machines and roller, the switching magnetic-resistance electricity The output shaft of machine is connected by reduction box with the roller, and the first flexible bar assembly and second flexible group are provided with the roller Part is used to recover the oil.
Further, flexible bar assembly described in every group includes fixed pulley, flexible link and oil well pump, one end of the flexible link It is connected with the oil well pump, the other end is connected to the roller by the fixed pulley.
Further, the roller is divided to two regions, distinguishes reverse-winding flexible link described in one group.
Further, the extracting device of oil also includes the support for supporting, and the height of the support is 2-3 rice.
Further, arrangements for speed regulation are provided with the switched reluctance machines, for adjusting the switched reluctance machines Rotating speed.
Compared with prior art, the utility model at least has the advantages that:
The utility model on roller by setting the first flexible bar assembly and the second flexible unit, using the shape of one drag two Formula, two mouthfuls of wells mutual counterweight of polished rod load in pumping crude oil, reduces the electric energy consumed during conventional pumping unit balancing weight displacement, The power consumption of another oil pumper is saved, and uses switched reluctance machines, power factor is approximately 1, and starting current is small, profit Its commutating period is set with controller, toggle speed can be slowed down when commutating and starting and extend the startup time, very well Solve the problems, such as the reversing impact of oil pumper, commutation is very steady.
Further, jig frequency is matched according to oilwell produced fluid amount and pump footpath, stroke, passes through the speed governing of switched reluctance machines Transposition is controlled to rotating speed, and according to the requirement of stroke, the height of support is arranged into 2-3 rice, the stepless of jig frequency can be achieved Adjustment.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Wherein:1. the first flexible bar assembly;2. the second flexible bar assembly;3. fixed pulley;4. flexible link;5. oil well pump;6. Roller;7. reduction box;8. arrangements for speed regulation.
Embodiment
The utility model provides a kind of switched reluctance machines one drag two extracting device of oil, and using switched reluctance machines, it is suitable For frequently playing braking and rotating, electric efficiency is high, starting torque is big, power factor (PF) is high, and motor speed can automatically adjust, because This can use it to drive two sets of computer collecting systems, and efficiency is higher, and adjust rate of oil production according to oil well liquid output situation, and realization used The digitlization of journey and intelligentized control method.In order to overcome the shortcomings of existing oil production equipment, using flexible rod, driven using roller Flexible rod driving oil well pump is reciprocating from oil pipe bottom to well head, reduces Paraffin Removal, the work of antiscale, Er Qiejian Pump is easy.
Referring to Fig. 1, the utility model discloses a kind of switched reluctance machines one drag two extracting device of oil, including switching magnetic-resistance Motor and roller 6, the output shaft of the switched reluctance machines are connected by reduction box 7 with the roller 6, the switching magnetic-resistance electricity Arrangements for speed regulation 8 are provided with machine, two groups of flexible units are correspondingly arranged on the roller 6 and are used to recover the oil.
Wherein, the flexible unit includes the first flexible flexible unit 2 of bar assembly 1 and second, flexible unit described in every group Including fixed pulley 3, flexible link 4 and oil well pump 5, one end of the flexible link 4 is connected with the oil well pump 5, and the other end passes through institute State fixed pulley 3 and be connected to the roller 6.
When switched reluctance machines are connected by axle with reduction box 7, switched reluctance machines high-speed rotation, 7 turns of reduction box is driven Dynamic, the high speed rotary motion that switched reluctance machines exports is changed into low-speed rotation by reduction box 7, reduction box 7 by axle and Roller 6 connects, and roller 6 is divided to two regions, distinguishes reverse-winding one group of flexible link 4, one end of flexible link 4 and passes through fixed pulley 3 After support, change direction, flexible link 4 does rotation fortune perpendicular to well head, bottom connection oil well pump 5, roller 6 with reduction box 7 Dynamic, the take-up on roller 6 of one of which flexible link 4, another group of flexible link 4 unwrapping wire on roller 6, the drive of flexible link 4 underground is taken out Fuel feed pump plunger moves up and down, and liquid is lifted to well head from oil pipe, so as to complete whole pumping process.
