Abstract
The utility model relates to a deep-drawing pump with inverter for oil extraction belonging to the class of oil extraction underground oil-well pump. When the oil field is in the middle and late period of mining or encounters less permeable layer, the movable liquid level in the oil well decreases gradually, which cause difficulty to pumping oil with the oil-well pump. The existing technique solves the problem by deepening the pump sling and increasing the ground device dynamic force, which increases the oil pumping cost undoubtedly. In order to realize the purpose, a reverser is provided between the cross pump oil-well pump and the fluid-increasing oil-well pump in the utility model. Double upward tension of the pumping rod can be generated through the clutch transmission of the wheel and rack inside, which drives the oil-well pump moving upward and discharging liquid and improve the oil flow speed. When the pumping unit goes upward, a reaction is generated by the lower oil-well pump under the function of the gravity and the reverser, and the reaction assists the pump sling to go upward, which balances the pumping unit working and saves the energy. So the device can be populated in the deep pumping and benefit increasing of the oil well widely.
Description
Technical field:
The utility model relates to a kind of oil recovery deep oil well pump with reverser, belongs to oil recovery downhole pump class.
Background technique:
The oil field enters the middle and later periods or when the saturating layer strip of low pressure and low permeability recovers the oil in exploitation, the producing fluid level of oil well can reduce gradually, therefore, requires the pump osmanthus of down-hole oil production pump is deepened thereupon, ground installation and power consumption are also increased thereupon, thereby the exploitation difficulty is strengthened.Therefore must take to improve pump efficiency, deepen pump and hang balanced oil extractor, and the measure of increasing producing pressure differential is only effective measure.
Summary of the invention:
The purpose of this utility model is a kind of oil recovery deep oil well pump with reverser that provides in order to overcome above-mentioned shortcoming, can not change the low block infiltration of realization low yield oil reservoir oil well production increasing under the existing ground installation condition.
The utility model is to realize like this.For realizing that above-mentioned task the utility model is the pump oil extraction pump more by being connect by the oil pipe screw thread, increase that liquid deep oil well pump and sand control screen form, at described pump oil extraction pump more and increase between the liquid deep oil well pump to link and be knotted a reverser with pipe wire.
Described reverser is to be equipped with in a shape is the housing of cylinder type that to overlap gears with two sizes be upper and lower two groups of cone pulleys of one group, the tooth bar interlock identical with the cone pulley tooth module arranged on cone pulley, wherein a toothed rack is engaged on the teeth of upper and lower parallel two small gears, join with the bottom sucker rod then, another toothed rack is engaged on the teeth of the gearwheel that is parallel to each other up and down, and joins with the top sucker rod.
The utility model working method is to realize like this;
The utility model is when being in the working state of pumping unit down stroke, oil well pump oil stream is except that overcoming normal oil well internal resistance, and the residual oil that is produced thus flows and to load with lotus and can produce the pulling force that twice makes progress by reverser, can drive the bottom and increase the up discharge opeing of liquid deep oil well pump, can make simultaneously oil reservoir moment generation negative pressure again, thereby can improve the flowing velocity of oil stream, when the top oil well pump when normally carrying out suction operation, as pumping unit as being in the down stroke state, this moment, the inverse electromotive force that produces just can reduce, when pumping unit is up, the bottom increases the liquid deep oil well pump and hangs under the action of gravity, produce reaction force by reverser again, assist the top pump to hang up row, and in balanced oil extractor, realize energy-conservation.
The utility model compared with prior art has distinguishing feature.
Because this device is at existing pump oil extraction pump more and increase and utilize pipe wire to link between the liquid deep oil well pump to follow a reverser, by tooth bar in the reverser and cone pulley interlock, and utilize pumping unit upstroke working state, can produce one times and drive the bottom to up pulling force and increase that the liquid deep oil well pump is up to carry out discharge opeing, thereby can improve oily flow velocity degree, when pumping unit is descending, the inverse electromotive force that is produced will reduce, by reaction force, can assist the top pump to hang up row, realize energy-conservation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the reverser structural representation.
Among the figure by 1, pump oil extraction pump more, 2, reverser, 3, increase the liquid deep oil well pump, 4, oil pipe, 5, sucker rod, 6, sand control screen, 7, sleeve pipe, 8, tooth bar, 9, gearwheel, 10, small gear forms.
Embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
Getting over pump oil extraction pump 1 among Fig. 1 is the logical oil extraction pump of a Daepori,, is connected with the ground pumping unit with sucker rod 5 in the pump in binding is lowered to the oil well of sleeve pipe 7 by the oil pipe screw thread.Oil pipe 4 is that 21/2 o'clock oil pipe connects more the pump oil extraction pump respectively and increases liquid deep oil well pump 3, reverser 2 and sand control screen 6.
Fig. 2 reverser 2 shapes are the housing of cylinder type, two large and small gears that overlap 9,10 be housed be upper and lower two groups of cone pulleys of one group in the housing, the tooth bar interlock is arranged on cone pulley, wherein rooted tooth wheel is engaged on the teeth of upper and lower two small gears 10 that are parallel to each other, join with the bottom sucker rod then, another toothed rack is engaged on the upper and lower gearwheel that is parallel to each other 9 teeth and with top sucker rod 5 joins.
Increase the liquid deep oil well pump and be attached at reverser 2 bottoms, join with sucker rod 5 with oil pipe.Described pump oil extraction pump 1 pump more directly is 30mm, can be lowered in 1800 meters the oil well, oil pumping increases liquid deep oil well pump 3 and is pump footpath 25mm, can be lowered to 2600 meters the interior oil pumping of oil well, 102 millimeters of reverser external diameters, big small gear score is not 1: 2,1: 1.5, and the casing diameter that this instrument is suitable for maximum slope in the well≤15 degree is oil well work in 5.5 o'clock, 7 o'clock, maximum lifting rate 12m
