Abstract

The utility model relates to a conventional crank double-direction balancing traveling beam double-donkey headed twinhole pumping unit, which mainly comprises a crank, a gear box, a main rack, a connecting rod, a donkey head, a traveling beam, and a counterpoise and is characterized in that: one end of the traveling beam is provided with a donkey head, while the output shaft of the gear box is fixed with a double-direction balancing crank. The utility model is applicable for the cluster well oil extraction. By using the loads of two oil wells not only can balance the pumping unit, but also can extract oil from two adjacent oil wells, thus saving a pumping unit so as to save 50 percents energy and reduce the difference between the maximum and minimum working currents of the pumping unit so as to save 10 percents energy. The utility model has the advantages of occupying fewer areas, shortening road repairing and wiring mileage, and reducing oil extraction production cost.

Description

The two horse head twin-well oil-pumping machines of conventional crank bidirectional balancing slide beam

Technical field

The utility model belongs to the oil pumping unit field, relates to the two horse head twin-well oil-pumping machines of a kind of conventional crank bidirectional balancing slide beam specifically.

Background technique

Oil field oil pumping unit kind is more, and wherein a kind of is the normal conventional beam pumping unit, is provided with horse head at the right-hand member of walking beam, and crank is in the left end of reduction gearbox output shaft, and an end of reduction gearbox output shaft and crank is fixed.Another kind is the front-located mode pumping unit, is provided with horse head at the left end of walking beam, and crank is in the right-hand member of reduction gearbox output shaft.Above-mentioned pumping unit can only carry out single oil well oil-pumping operation, and a bite oil well need dispose a pumping unit.Above-described pumping unit mainly contains crank, speed reducer, body frame, connecting rod, horse head, walking beam and equilibrium block etc.Described horse head is installed in an end of walking beam, and the walking beam of pumping unit links to each other with the axle of body frame upper end; The connecting rod of pumping unit links to each other with axle on walking beam and the crank respectively; Described crank is provided with equilibrium block.The motion of motoring speed reducer is made circular movement thereby order about crank, under the effect of connecting rod, makes the horse head of walking beam one end do reciprocal moving up and down, and oil is extracted out from well.After pumping unit is transported to the scene, all will adjust the load of oil well by the position of adjusting the equilibrium block on the crank, this is those of ordinary skill in the art's common sense knowledge.

The model utility content

The purpose of this utility model is to overcome the problem that prior art exists, a kind of two horse head twin-well oil-pumping machines of conventional crank bidirectional balancing slide beam that cluster wells production is used that are used for are provided, simultaneously adjacent two mouthfuls of oil wells are pumped with a pumping unit with realization, to save floor space, save energy consumption, reduce cost for oil production etc.

The purpose of this utility model realizes by the following technical solutions:

The two horse head twin-well oil-pumping machines of a kind of conventional crank bidirectional balancing slide beam mainly comprise crank, speed reducer, body frame, connecting rod, horse head, walking beam, equilibrium block, and it is characterized in that: the other end at described walking beam has additional horse head.

The two horse head twin-well oil-pumping machines of above-mentioned conventional crank bidirectional balancing slide beam is characterized in that: be fixed with bidirectional balanced crank on described reduction gearbox output shaft.

The utility model compared with prior art has the following advantages:

(1) the utility model is applicable to cluster wells production, comes balanced oil extractor with the load of two mouthfuls of oil wells, can pump to two mouthfuls of adjacent oil wells simultaneously, can save a pumping unit, energy-conservationly reaches 50%; Also can be changed into the individual well pumping unit after wherein a bite well stops adopting and use, another mouthful oil well is continued oil pumping.

(2) the utility model working power is more reasonable, has reduced the poor of the motor maximum operating currenbt of pumping unit and minimum working current, and only this just can save energy 10%.

(3) the utility model floor space is few, and minimizing is repaired the roads, the stringing mileage, can reduce the oil recovery cost of production.

Description of drawings

Accompanying drawing is the utility model structure, working principle schematic representation.Wherein

1-crank 2-speed reducer 3-body frame 4 connecting rods

5-horse head 6-walking beam 7 equilibrium blocks

Embodiment

Embodiment:

Now the utility model is further described as follows with embodiment in conjunction with the accompanying drawings: as seen from accompanying drawing, the two horse head twin-well oil-pumping machines of the conventional crank bidirectional balancing slide beam of the utility model, mainly comprise crank 1, speed reducer 2, body frame 3, connecting rod 4, horse head 5, walking beam 6, equilibrium block 7, it is characterized in that: the other end at described walking beam 6 has additional horse head 5.

The two horse head twin-well oil-pumping machines of above-mentioned conventional crank bidirectional balancing slide beam, its feature is levied and is: be fixed with bidirectional balanced crank 1 on described speed reducer 2 output shafts.

Just as described above, on speed reducer 2 output shafts, be fixed with bidirectional balanced crank 1 (crank 1 is positioned at horizontal position).Behind above-mentioned pumping unit installation in position, the load of two mouthfuls of wells is adjusted in the position of adjusting the equilibrium block 7 on the crank 1.When stopping adopting, the left side oil well equilibrium block 7 can be transferred to the left end of crank 1; When the oil well on right side stops adopting, equilibrium block 7 can be transferred to the right-hand member of crank 1.When two mouthfuls of wells recovered the oil simultaneously, equilibrium block 7 was near the mid point of crank 1.Equilibrium block 7 is in crank 1 right positions in the utility model accompanying drawing, shows that the right side oil well has stopped recovering the oil.
