Abstract
The invention relates to a mechanical jack type hydraulic double-well oil pumping machine which is characterized by comprising main frames, a main hydraulic cylinder, auxiliary hydraulic cylinders, a turbine reducer and a permanent magnet reciprocating motor. A rotary shaft of the permanent magnet reciprocating motor is connected with a worm of the turbine reducer. A piston rod of the main hydraulic cylinder is in transmission connection with a screw in the turbine reducer. The main frames are mounted on two sides of the main hydraulic cylinder respectively. One auxiliary hydraulic cylinder is mounted on each main frame. The two auxiliary cylinders are driven by the main hydraulic cylinder. Two adjacent oil wells can be pumped simultaneously with one oil pumping machine, floor space is saved, energy consumption is saved, oil extraction cost is lowered and the like.
Description
Technical field
The invention belongs to the oil recovery machiner field, relate to a kind of mechanic jacks formula hydraulic pressure twin-well oil-pumping machine that does not have walking beam specifically.
Background technology
There are many oil recovery machiners in each oil field at present, wherein a kind of is no beam pumping unit, blue elephant mainly is chain drive pumping unit, chain drive pumping unit is subjected to the restriction maintenance difficult of chain, need renewal technology, and do not have trip grain oil pumper and be generally the individual well oil pumper, be that a bite oil well need dispose an oil pumper, now each oil field is because taking up an area of, reasons such as management are beaten many cluster wells, adjacent two mouthfuls of oil wells can reduce very big lifting expenses with an oil pumping machine oil pumping, several twin-well oil-pumping machines in the existing Chinese patent are failed to solve and are adjusted two mouthfuls of oil well well spacings at any time, two mouthfuls of oil wells of balance load and become the problem of individual well oil pumper when a bite oil well stops adopting is so it is universal also to obtain practical application till now.
Summary of the invention
For overcoming the defective of prior art, the invention provides a kind of mechanic jacks formula hydraulic pressure twin-well oil-pumping machine of the no walking beam for cluster wells production.To realize simultaneously adjacent two mouthfuls of oil wells being pumped simultaneously saving floor space, saving energy consumption, reduction cost for oil production etc. with an oil pumper.Technical scheme of the present invention is: a kind of mechanic jacks formula 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 rotating shaft of described 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 the worm speed reducer is in transmission connection, both sides at described main hydraulic cylinder are separately installed with body frame, on described each body frame secondary hydraulic cylinder is installed all, two secondary hydraulic cylinders all drive by main hydraulic cylinder.
Described main hydraulic cylinder is communicated with two pipelines, and wherein an end of first pipeline communicates with the cavity of main hydraulic cylinder piston rod one side, and the other end communicates with wherein a secondary hydraulic cylinder; 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 other one secondary hydraulic cylinder.
The piston rod of described secondary hydraulic cylinder arranges downwards, is connected with sucker rod.
Mechanic jacks formula hydraulic pressure twin-well oil-pumping machine of the present invention has the following advantages:
1, the present invention has reduced Hydraulic Station owing to adopt novel power device permanent magnetism reciprocating motor directly to drive worm reduction gear, has simplified complicated transmission mechanism, has reduced energy loss and wearing and tearing, has reduced device fabrication cost and maintenance cost;
2, the load of two mouthfuls of oil wells of the present invention's energy balance, operating current is more reasonable, and can be used as the use of individual well oil pumper after a bite oil well stops to recover the oil, and can adapt to the different operating modes in oil field.
3, twin-well oil-pumping machine can be saved equipment cost and the energy loss of an oil pumper simultaneously to two mouthfuls of oil well oil-pumpings, energy-conservationly reaches 50%.

Referring to Fig. 1, the present invention relates to a kind of mechanic jacks formula hydraulic pressure twin-well oil-pumping machine, comprise body frame 1, main hydraulic cylinder 2, secondary hydraulic cylinder, worm speed reducer 4 and permanent magnetism reciprocating motor 5, the rotating shaft of described permanent magnetism reciprocating motor 5 is connected with the worm screw of worm speed reducer 4, screw in the piston rod of described main hydraulic cylinder 2 and the worm speed reducer 4 is in transmission connection, be separately installed with body frame 1 in the both sides of described main hydraulic cylinder 2, on described each body frame 1 secondary hydraulic cylinder is installed all, two secondary hydraulic cylinders 6,7 all drive by main hydraulic cylinder 2.
Described main hydraulic cylinder 2 is communicated with two pipelines, and wherein an end of first pipeline 8 communicates with the cavity of main hydraulic cylinder piston rod 3 one sides, and the other end communicates with wherein a secondary hydraulic cylinder 6; One end of second pipeline 9 communicates with the cavity of the opposite side of main hydraulic cylinder piston rod 3, and the other end communicates with other one secondary hydraulic cylinder 7.
Described secondary hydraulic cylinder 6,7 piston rod arrange downwards, are connected with sucker rod, and other oil pumping mechanism for example polished rod eye, wire rope etc. is prior art, is not described in detail herein.
Operating principle of the present invention is as follows: realize commutation by the rotating of permanent magnetism reciprocating motor, drive worm speed reducer, utilize the screw rotation in the worm speed reducer, the piston rod linear reciprocation that drags main hydraulic cylinder moves, one of them secondary hydraulic cylinder piston rod is risen, promote corresponding with it sucker rod, following oil well is pumped; In this hydraulic cylinder piston decline of opposite side simultaneously, corresponding with it sucker rod also descends thereupon.Make that two mouthfuls of oil wells replace mutually, mutual balance, realize that an oil pumper pumps simultaneously to two mouthfuls of oil wells.
