Description
Technical field
The invention belongs to oil recovery machiner field, relate to a kind of mechanical jack type hydraulic pressure twin-well oil-pumping machine without walking beam specifically.
Background technology
There are many oil recovery machiners in current each oil field, wherein one is without beam pumping unit, blue elephant is chain drive pumping unit mainly, chain drive pumping unit is by the restriction maintenance difficult of chain, need renewal technology, and be generally individual well oil pumper without trip grain oil pumper, namely a bite oil well needs configuration oil pumper, now each oil field is because taking up an area, the reasons such as management beat many cluster wells, adjacent two mouthfuls of oil wells oil pumping machine oil pumping can reduce very large lifting expenses, several twin-well oil-pumping machines in existing Chinese patent are failed to solve and are adjusted two mouthfuls of oil well well spacings at any time, balance two mouthfuls of oil well load and become the problem of individual well oil pumper when a bite oil well stops adopting, popularize so also do not obtain practical application till now.
Summary of the invention
For overcoming the defect of prior art, the invention provides a kind of mechanical jack type hydraulic pressure twin-well oil-pumping machine without walking beam for cluster wells production.To realize pumping to adjacent two mouthfuls of oil wells with an oil pumper simultaneously simultaneously, save floor space, save energy consumption, reduce cost for oil production etc.Technical scheme of the present invention is: a kind of mechanical jack type hydraulic pressure twin-well oil-pumping machine, comprise body frame, main hydraulic cylinder, secondary hydraulic cylinder, worm speed reducer and permanent magnetism reciprocating motor, the described rotating shaft of permanent magnetism reciprocating motor is connected with the worm screw of worm speed reducer, screw in the piston rod of described main hydraulic cylinder and worm speed reducer is in transmission connection, body frame is separately installed with in the both sides of described main hydraulic cylinder, each described body frame is all provided with secondary hydraulic cylinder, and two secondary hydraulic cylinders are all driven by main hydraulic cylinder.
Described main hydraulic cylinder is communicated with two pipelines, and wherein one end of first pipeline communicates with the cavity of main hydraulic cylinder piston rod side, and the other end communicates with the secondary hydraulic cylinder of wherein; One end of second pipeline communicates with the cavity of the opposite side of main hydraulic cylinder piston rod, and the other end communicates with an other secondary hydraulic cylinder.
The piston rod of described secondary hydraulic cylinder is arranged downwards, is connected with sucker rod.
Mechanical jack type hydraulic pressure twin-well oil-pumping machine of the present invention has the following advantages:
1, the present invention is owing to adopting novel power device permanent magnetism reciprocating motor Direct driver worm reduction gear, decreases Hydraulic Station, simplifies complicated transmission mechanism, reduce energy loss and wearing and tearing, reduce device fabrication cost and maintenance cost;
2, the present invention can balance the load of two mouthfuls of oil wells, and operating current is more reasonable, and after a bite oil well stops oil recovery, can be used as the use of individual well oil pumper, can adapt to the different operating mode in oil field.
3, twin-well oil-pumping machine can save equipment cost and the energy loss of an oil pumper simultaneously to two mouthfuls of oil well oil-pumpings, energy-conservationly reaches 50%.
Accompanying drawing explanation
Fig. 1 is agent structure schematic diagram of the present invention.
Detailed description of the invention
