Abstract
The utility model relates to an intelligent linked oil pumping unit of a well mouth. A main unit frame and an auxiliary unit frame are respectively arranged on a well mouth and on a well mouth. A cylinder-shaped linear motor stator and an oil pumping rod which are arranged on the main unit frame penetrate through a center hole of a mover to be driven by a pulley block in a matched mode through a steel cable and the pulley block and be connected with an oil pumping rod arranged at the center of the auxiliary unit frame. A balance weight hung on the pulley block is arranged at the lateral end of the main unit frame and is matched with the mover for auxiliary balance. The utility model adopts a cylinder-shaped linear motor to drive two oil pumping units to work, a traction motor and control equipment are reduced, and the equipment investment is reduced. The effect on saving electricity is obvious, and compared with an ordinary moving beam type oil pumping unit, the rate for saving electricity can reach 50%. The temperature rise of a section combined type primary winding is low.
Description
Technical field
The utility model relates to a kind of oil pumper, especially intelligent coordinated type well head oil pumper.
Background technology
At present, the beam pumping unit of oil field extensive use is to convert rotatablely moving of motor to oil pumper pump by reducer and quadric chain, drive downhole pump work, its complex structure, volume is big, weight is big, the efficient of adjustment parameter difficulty, device is low.
China Patent No. 96217683.9 discloses a kind of oil pumper that adopts linear electric motors to drive, the sucker rod of this oil pumper is to be fixed on the linear motor rotor of hollow structure with deck, locating piece on the mover of linear electric motors leans against on the limited post, keep the electromagnetism air gap and set upright well casing, wire rope on frame is by pulley two termination deck and balancing weights, the weight of balance rod weight and fluid column.The used linear electric motors of this oil pumper are short elementary stators of doing, long secondary trigger switch, and the distance of its operation is 2 times of stroke, has increased the height of derrick greatly, on structure, these linear electric motors are line inductance electromotor.Its electromagnetic push is little, and linear induction engine efficiency and power factor are very low, and electric energy loss is big.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of direct seat to drive the intelligent coordinated type well head oil pumper of two oil pumpers simultaneously with sectionally assembled cylindrical linear on well head.
In order to achieve the above object, the technical solution adopted in the utility model is: the equal respectively seat of mainframe and secondary frame is on well head and well head, mainframe is provided with the cylindrical linear stator and cooperates transmission to be connected with the sucker rod that secondary frame central position is provided with the centre bore that sucker rod passes mover through wire rope, assembly pulley and assembly pulley, and the mainframe side is provided with the balance weight that hangs on the assembly pulley and cooperates auxiliary balance with mover.
The utility model has the advantages that:
1, adopts a cylindrical linear to drag two oil pumper work, reduce a dragging motor and control appliance, significantly reduce equipment investment;
2, power savings is significantly compared power saving rate with common beam pumping unit and can be reached 50%;
3, the temperature rise of sectionally assembled elementary winding is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is that the equal respectively seat of mainframe 5 and secondary frame 12 is on well head 1 and well head 10, mainframe 5 is provided with cylindrical linear stator 4 and cooperates transmission to be connected with the sucker rod 11 that secondary frame 12 centres are provided with the centre bore that sucker rod 2 passes mover 3 through wire rope 8, assembly pulley 7 and assembly pulley 9, and mainframe 5 sides are provided with the balance weight 6 that hangs on the assembly pulley 7 and cooperate auxiliary balance with mover 3.
The stator 4 of described cylindrical linear is formed long elementaryly by several identical weak points are elementary, and total length is long for time level length adds stroke.
The utility model is work like this:
Intelligent coordinated type well head oil pumper adopts sectionally assembled cylindrical linear to drive two oil pumpers and works simultaneously.The stator 4 of flexible type linear electric motors is contained on the mainframe on the well head 5, and the endoporus that sucker rod passes mover 3 links to each other with mover 3, and by wire rope 8, the assembly pulley 9 on assembly pulley 7 and the secondary oil pumper, polished rod eye 13 are connected with sucker rod 14 mover 3 simultaneously.When the stator 4 of cartridge type linear electric motors feeds three-phase current, mover 3 is done upper and lower reciprocating motion, and the sucker rod that drives two oil pumpers is simultaneously done straight reciprocating motion, when main oil pumping machine oil pumping bar 2 is up, secondary sucker rod 14 is descending, the mutual balance of the weight of two oil pumping machine oil pumping bars.The thrust of cartridge type linear electric motors equals main oil pumper fluid column weight when the static load of two oil pumpers is identical.When sucker rod 2 is descending, thrust equals the weight of secondary oil pumper fluid column, this moment, balance weight was zero, when the static load of two oil pumpers is inequality, the thrust of motor equaled half that main oil pumper fluid column heavily deducts the heavy difference of two fluid columns when the sucker rod 2 of main oil pumper was up, the thrust of motor equals half that the driven machine fluid column heavily deducts the heavy difference of two fluid columns when sucker rod 2 is descending, and the sectionally assembled stator 4 of cylindrical linear adopts computers control, and segmentation connects in turn power supply.The stator 4 of work was only connected before mover 3 is corresponding with it, and stator 4 promptly cuts off later, and next group stator 4 is connected, and send electricity in proper order with this, after mover 3 runs to the top, oppositely with opposite connect in turn, the disjunction power circuit.Mover 3 is done straight reciprocating motion, drags two oil pumper work.
