By adopting the technical scheme, two adjacent wells can be extracted by adopting the same oil production equipment; when one oil well needs to stop production for workover, the normal production can be carried out on the other well; therefore, the mechanical use efficiency of the system can be improved, the equipment investment, energy resource consumption and management maintenance charge can be reduced, the oil production cost is reduced, and the economical benefits can be improved greatly.
Description
Technical field
The utility model relates to a kind of oil pumper that is used for oil field cluster well exploitation, particularly relates to a kind of driving low-laying type long-stroke energy-saving twin-well oil-pumping machine.
Background technology
The oil field nonflowing well adopts oil pumper to promote oil well pump and pumps and pump.Existing oil field pumping unit commonly used is mainly beam pumping unit, is commonly called as " machine of kowtowing ", all adopts the configuration of a well one machine.And during oilfield exploitation often on a well site or platform, get out some mouthfuls even up to a hundred mouthfuls of wells, the well head of each well is at a distance of less than several meters, the cluster well of different azimuth is then stretched in each well shaft bottom.So both can save drilling cost, be convenient to the centralized management of oil well after the completion, and can reduce gathering and transferring process again, save the investment of human, financial, and material resources.
For existing cluster well exploitation, well head still adopts a well one machine to pump at a distance of several meters.And in existing technology, disclosed a kind of double well interactive beam-rope pulley autobalanced oil pumping unit patent is to drive devices such as two cover horse heads, walking beam, balance weight with a steer motor, and its mechanical efficiency is low, and maintaining is frequent; The synchronous draw twin-well oil-pumping machine of disclosed a kind of rare earth permanent magnet gearless and a kind of gearless driving oil pumper patent, removed reducing gear, directly done forward and reverse motion, can't accurately regulate counterweight with the driven by motor wire rope, certainly will lower efficiency, also have problems in the practical application; The automatically controlled oil pumper of disclosed a kind of crane type twin-well also can't be regulated counterweight, to the drilling well bad adaptability; Disclosed submerged type twin-well hydraulic pumping unit is applicable to the seabed oil pumping, adopts hydraulic drive, cost height, maintenance cost height.
Summary of the invention
Key technical problem to be solved in the utility model is that pumping unit one machine one well of the existing cluster well of change is a machine twin-well, solve the equilibrium problem of adjacent two mouthfuls of well counterweights, so the purpose of this invention is to provide a kind of simple in structure, easy to use, safe and reliable, be easy to adjust the energy-efficient oil production equipment of running parameter.
For achieving the above object, the utility model is by the following technical solutions:
The main frame that the utility model comprises base and is fixed on the base top, on main frame, set up two extraction mechanisms, one end of each extraction mechanism connects the oil well device by the lead rope, the lead rope of the extraction mechanism other end is wrapped on the same drive motors, it is characterized in that: on described main frame, set up upper mounting plate, extraction mechanism is positioned on the upper mounting plate, and described drive motors is positioned on the base.
Described extraction mechanism comprises at least two guide wheels that are positioned at the main frame top, and guide wheel is fixed on the upper mounting plate; The front end lead rope that guide wheel is drawn connects the oil well device by polished rod eye, and the rear end lead rope that guide wheel is drawn is wrapped on the same drive motors.
Described extraction mechanism comprises four guide wheels that are positioned at the main frame top.
Described drive motors comprises reductor and the motor that is connected with reductor.
Described motor is a switched reluctance machines.
The work large platform is set on the described base, and reductor and motor are positioned on the work large platform.
Be provided with bearing diagonal between described main frame and the upper mounting plate.
Adopt the utility model of technique scheme, it utilizes a cover oil production equipment that adjacent two mouthfuls of wells are recovered the oil simultaneously, when a bite oil well wherein need stop production when carrying out workover treatment, also allow another mouthful well is carried out ordinary production, improved the system mechanics service efficiency, reduce equipment investment, energy consumption and management and maintenance expense, reduced cost for oil production, increased substantially economic benefit.
Specifically, the utlity model has following advantage:
1, a machine twin-well is saved equipment investment;
2, switched reluctance machines drives, and starting current is little, the power factor (PF) height, and power savings is obvious;
3, put at the bottom of the driving platform, easy to maintenance, greatly reduce maintenance cost, but structural member is relative with the belt materials more;
4, can monolaterally promote during well workover;
5, adjustable balance weight joint, during a machine twin-well, counterweight participates in the adjusting of two mouthfuls of well balances, and during well workover, counterweight can be used as individual well and promotes;
6, long stroke, slow jig frequency;
7, safety is good.Braking steadily, the hydraulic lock function can make sucker rod be stopped at optional position in the stroke reposefully; Have overload protection, breaking rope protecting function, do not turn over machine, do not pound well head;
8, floor space is little, from heavy and light.
