Abstract

The invention relates to a combined oil pumping unit. At present, a beam-pumping unit most popular at home and abroad has the defects of long driving chain, low mechanical efficiency, hardly improved system efficiency and relatively large consumption of steel, energy and the like. In the combined oil pumping unit provided by the invention, a prying power unit and a head sheave rack unit are independent two sets of equipment, are convenient to integrally assemble, disassemble, transport and maintain, can be separated and combined, is suitable for catch rotation operation areas and can reduce the total number of installed oil pumping units; and the combined oil pumping unit can be used for single-well and twin-well operations. Two head sheave rack units are symmetrically arranged on the two sides of the prying power unit so as to form twin-well operation equipment; and single-well combined equipment can be formed by removing one head sheave rack unit. When twin wells are combined, two wells are dragged by one motor and share one driving wheel, and the loads of two wells are operated in a mutual weight balancing manner such that the driving chain of the oil pumping unit is shortened and the efficiency of the overall oil pumping unit is improved; therefore, the effect of energy conservation is achieved.

The combined type oil pumper
Technical field:
The invention belongs to oil recovery machiner field, oil field, particularly relate to a kind of combined type oil pumper.
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 combined type oil pumper is provided, individual well operation and twin-well operation can arbitrary combination, and the well spacing adjustable range is big.
Combined type oil pumper provided by the invention is characterized in that comprising: base (1), ballast box (2), frame (3), polished rod eye (4), head sheave (5), day wheel bearing (6), transmission rope (band) (7), driving wheel bearing (8), driving wheel (9), frame support (10), motor (11), input shaft coupling (12), reducer (13), output shaft coupling (14), electrical control cubicles (15), skid power unit (16), head sheave rack unit (17); Described base (1) is made with the welding of H shaped steel, welds with frame (3); Described ballast box (2) is made by the steel plate welding, is connected with head sheave (5) by wire rope (band); Described frame (3) is made with H shaped steel, and top is connected with day wheel bearing (a 6) bolt; Described head sheave (5) rolls welding with steel plate and makes; Described wire rope (band) top is walked around head sheave (5) and is connected with polished rod eye (4), and the bottom is connected with driving wheel (9); Described frame support (10) top is connected with the frame bolt, and the bottom is connected with base (1) bolt; Described input shaft coupling (12) one ends are connected the other end and are connected with reducer with motor; Described output shaft coupling (14) one ends are connected with reducer output shaft, and the other end is connected with driving wheel; Described skid power unit (16) is welded to form with i iron, and Electric Appliance Cabinet (15), driving wheel (9), output shaft coupling (14), reducer (13), input shaft coupling (12), motor (11) are installed above; Described head sheave rack unit (17) is welded to form with i iron, with frame (3) welding, frame (3), head sheave (5), frame support (10), ballast box (2) is housed above.
According to combined type oil pumper provided by the invention, skid power unit (16) and head sheave rack unit (17) are two groups of equipment independently, are convenient to integral disassembly, assembly, transportation, maintenance, can separate, make up, be applicable to that wheel (stream) adopts (oil) operation area, reduce total platform number that oil pumper is installed; Can be used for the individual well operation, also can be used for the twin-well operation, a head sheave rack unit adds a skid power unit and is combined into the individual well implement; Skid power unit two a sides symmetry is installed two head sheave rack units, is combined into the twin-well implement; Two mouthfuls of wells drag with a motor, a shared driving wheel, the load of the two mouthfuls of wells mode of counterweight each other moves, crankshaft balance weight rotation mode storage of potential energy by original walking beam machine, and become the rectilinear motion mode storage of potential energy, and the oil pumper driving-chain is shortened, the efficient of complete machine improves, running cost reduces, thereby has reached energy-conservation effect.
