Abstract
The invention provides a dual-well pumping unit which is characterized by comprising a stand, a weight box, a guide wheel support A hinge, a guide wheel support, an upper platform, a guide wheel rack, a guide wheel, a driving rope (belt), a guide wheel rack hinge, a driving wheel, a speed reducer, a coupling, a motor, an electric control cabinet and a door type support frame. According to the dual-well pumping unit provided by the invention, two wells are trailed by one motor and share one driving wheel; the two wells operate in a mutually-weighted manner; a traditional crank balance block rotating mode for storing potential energy in a beam pumping unit is changed into a linear motion mode for storing potential energy, so that a driving chain of the pumping unit is shortened, the efficiency of the entire unit is improved and the operation cost is reduced; the balance effect of the pumping unit is improved, the vibration and the starting torque are reduced and the operation is stable; and the phenomenon of lower load-carrying is changed, thereby the effect of saving energy is achieved.
Description
Technical field:
The invention belongs to oil recovery machiner field, oil field, particularly relate to a kind of twin-well oil-pumping machine.
Background technology:
At present, oil production equipment is most popular both at home and abroad is beam pumping unit, and this oil pumper is intrinsic owing to four-bar linkage structure itself, its transmission chain length, and mechanical efficiency is low; The counter weight construction of beam pumping unit has also determined it to have pulse big, low, the inefficient shortcoming of load factor.Under this condition: ground installation and underground equipment are difficult to reach rational coordination, and system effectiveness is difficult to improve; The steel consumption of equipment, energy consumption etc. are all bigger.At present, oil pumper is oil field power consumption rich and influential family, and its power consumption accounts for 40% of oil field total electricity consumption, and overall efficiency is very low, according to investigations generally about 30%.Varying load when the oil-field oil pumper load is: the branch that dynamic and static load characteristic is arranged.The starting torque of starting original state requirement dragging motor is 3-4 a times of oil pumper actual loading, and starting torque is the first element of oil pumper apolegamy motor.Must mate not goodly when starting torque is suitable for then bearing power, running load power is all much smaller than the rated power of motor, promptly so-called " low load with strong power " phenomenon.Superfluous oil pumping ability makes the idle extraction time of oil pumper increase, and causes the grid electricity fee cost of oil mining high, and energy waste is very serious.As seen the energy-saving potential of oil pumper is considerable.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of simple in structure, energy consumption is low, balance good, reversing impact is little, easy to maintenance twin-well oil-pumping machine is provided.
Twin-well oil-pumping machine provided by the invention is characterized in that comprising: frame (1), ballast box (2), directive wheel support A hinge (3), directive wheel support A (4), upper mounting plate (5), guiding wheel carrier A (6), directive wheel A (7), transmission rope (band) A (8), guiding wheel carrier A hinge (9), driving wheel (10), transmission rope (band) B (11), guiding wheel carrier B hinge (12), directive wheel B (13), guiding wheel carrier B (14), directive wheel support B (15); Directive wheel supports B hinge (16), reducer (17), shaft coupling (18), motor (19), electrical control cubicles (20), gate-type bracing frame (21); Described frame (1) is connected with upper mounting plate (5) bolt, and described ballast box (2) is welded to form by steel plate, is connected with driving wheel (10) with wire rope (band); Described directive wheel supports A, B (4) (15) to be made up of rectangle steel, and top is connected with guiding wheel carrier A, B (6) (14) bolt, and A is supported with directive wheel in the bottom, B hinge (3) (16) is connected; Described guiding wheel carrier A, B (6) (14) are welded to form with i iron, are connected with hinge (9) (12); Described directive wheel (7) (13) is welded with steel plate, and described driving wheel (10) is welded with steel plate, and transmission rope (band) A, B (8) (11) are wrapped on the driving wheel; Reducer (17) is connected with motor (19) by shaft coupling (18); Described gate-type bracing frame (21) is welded to form by angle steel, and the top is provided with pulley, and the bottom is connected with guiding wheel carrier A, B hinge (9) (12), and the middle part is connected with bearing diagonal (22) bolt, and the bearing diagonal bottom is connected with upper mounting plate (5) bolt.
According to twin-well oil-pumping machine provided by the invention, two mouthfuls of wells drag with a motor, a shared driving wheel, two mouthfuls of wells mode of counterweight each other move, by the crankshaft balance weight rotation mode storage of potential energy of original walking beam machine, and become the rectilinear motion mode storage of potential energy, the oil pumper driving-chain is shortened, the efficient of complete machine improves, and running cost reduces; Improved the counterbalance effect of oil pumper, reduced vibrations, operated steadily, staring torque reduces, changed " low load with strong power " thus phenomenon reached energy-conservation effect.
