The problems that the surface of a plunger and the part which is not inserted into a pump barrel of the existing long-plunger short-pump barrel pump are seriously scaled and the plunger is easy to block are mainly solved. The method is characterized in that: the upper end of the pump barrel (1) is connected with an upper joint, the lower end of the pump barrel (1) is connected with a fixed valve, the lower end of the fixed valve is connected with a lower joint, the upper end of the plunger (2) is connected with an upper traveling valve, the lower end of the plunger (2) is connected with a lower traveling valve, the plunger (2) is arranged in the pump barrel (1), the outer diameter of the upper traveling valve cover (3) is equal to the outer diameter of the plunger (2), an elastic rubber sheet (4) is arranged in an outer groove of the plunger (2), and more than 1 rigid sealing ring (5) is arranged in the elastic rubber sheet (4). The equal-diameter self-adaptive plunger anti-scaling clamp oil well pump for the oil field rod-pumped well has the characteristics of difficulty in scaling and prolonging of pump detection period.
Description
Technical field
The utility model relates to field of oil field oil extraction oil well pump used, especially the diameter adaptive plunger anti-scaling card oil well pump such as oilfield pumping well.
Background technique
In field of oil field oil extraction, long-plunger short pump barrel oil well pump is used widely.And the plunger surface of long-plunger short pump barrel pump and not enter the fouling of pump barrel part serious, often occur plunger stuck phenomenon, have impact on production time efficiency, fouling peak period pump detection period, less than 75 days, have impact on development effectiveness.
Summary of the invention
In order to solve the plunger surface of existing long-plunger short pump barrel pump and not enter the fouling of pump barrel part seriously, the problem that easy plunger is stuck.The utility model provides the diameter adaptive plunger anti-scaling card oil well pumps such as a kind of oilfield pumping well.The diameter adaptive plunger anti-scaling card oil well pumps such as this oilfield pumping well have less scaling, extend the feature of pump detection period.
The technical solution of the utility model is: the diameter adaptive plunger anti-scaling card oil well pumps such as this oilfield pumping well comprise pump barrel and plunger.Pump barrel upper end is connected with upper connection, pump barrel lower end is connected with standing valve, standing valve lower end is connected with lower contact, its upper end is connected with upper traveling valve, plunger lower end is connected with lower travelling valve, and plunger is placed in pump barrel, and upper traveling valve cover external diameter is mutually isometrical with plunger outer diameter, be provided with elasticity rubber in the outer groove of plunger, elastic gum intracutaneous is provided with more than 1 steel sealing ring.
The utility model has following beneficial effect: the diameter adaptive plunger anti-scaling card oil well pumps such as this oilfield pumping well are connected with upper connection owing to adopting pump barrel upper end, pump barrel lower end is connected with standing valve, standing valve lower end is connected with lower contact, its upper end is connected with upper traveling valve, plunger lower end is connected with lower travelling valve, plunger is placed in pump barrel, upper traveling valve cover external diameter is mutually isometrical with plunger outer diameter, be provided with elasticity rubber in the outer groove of plunger, elastic gum intracutaneous is provided with the structure of more than 1 steel sealing ring.Utilize steel sealing ring radial expansion on elasticity rubber, utilize isometrical upper traveling valve cover and plunger simultaneously, realize long-plunger short pump barrel pump less scaling, extend the object of pump detection period.The diameter adaptive plunger anti-scaling card oil well pump such as this oilfield pumping well has less scaling thus, extends the feature of pump detection period.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
1-pump barrel in figure, 2-plunger, 3-upper traveling valve cover, 4-elasticity rubber, 5-steel sealing ring.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the diameter adaptive plunger anti-scaling card oil well pump such as this oilfield pumping well comprises pump barrel 1 and plunger 2.Pump barrel 1 upper end is connected with upper connection, pump barrel 1 lower end is connected with standing valve, standing valve lower end is connected with lower contact, plunger 2 upper end is connected with upper traveling valve, plunger 2 lower end is connected with lower travelling valve, plunger 2 is placed in pump barrel 1, and upper traveling valve cover 3 external diameter is mutually isometrical with plunger 2 external diameter, prevents the local fouling of upper traveling valve cover 3 and the necking down of plunger 2 joint from causing holddown.Be provided with elasticity rubber 4 in the outer groove of plunger 2, in elasticity rubber 4, be provided with more than 1 steel sealing ring 5.Steel sealing ring 5 can in elasticity rubber 4 radial expansion, ensure that and to coordinate between pump barrel 1 with steel sealing ring 5 closely, prevent hydraulic slip in well.
Working procedure:
During the diameter adaptive plunger anti-scaling card oil well pump upstrokes such as this oilfield pumping well, in oil jacket annular space and oil pipe under fluid pressure differential effect, determine valve and open, travelling valve is closed, and liquid discharged by pipeline earthward; Down stroke, standing valve is closed, and pump internal pressure raises gradually, and travelling valve is opened, and liquid is discharged in oil pipe.Upper traveling valve cover 3 external diameter and plunger 2 external diameter such as to be designed at the gauge structure, prevent upper traveling valve cover 3 to be connected bottleneck fouling with plunger 2 and cause holddown, plunger 2 there is steel sealing ring 5 tandem compound, when after pump barrel fouling, flexible rubber 4 between plunger 2 and steel sealing ring 5, between plunger 2 and pump barrel 1 during fouling, steel sealing ring 5 can radial expansion, auto-compensation plunger 2 and pump barrel 1 gap, adapt to fouling environment.
The diameter adaptive plunger anti-scaling card oil well pumps such as this oilfield pumping well, when not taking to add boiler compound, reduce ternary composite drive produced well inspection pump number of times, reduce operating rate, obviously extend pump detection period.Within 2014, at ternary composite driving block field experiment 3 mouthfuls of wells, after experiment, average pump efficiency reaches 50.9%, and average dirty card pump detection period 38 days before experiment, dirt card does not occur after experiment, and the phase of being excused from a college course reaches 259 days.On January 12nd, 2014 tests the diameter adaptive plunger anti-scaling card oil well pumps such as this oilfield pumping well at apricot 5-D4-SE10 well, this well test production fluid 40t/d day before yesterday, submergence 65m, pump efficiency 49.4%; Day production fluid 42t/d, submergence 51m after test, pump efficiency 51.8%, it is normal that merit figure shows operating mode, average dirty card pump detection period 36 days before test, and when ground does not drip liquid boiler compound, the phase of being excused from a college course reaches 261 days; On January 13rd, 2014 tests the diameter adaptive plunger anti-scaling card oil well pumps such as this oilfield pumping well at apricot 6-30-SE16 well, this well test production fluid 36t/d day before yesterday, submergence 180m, pump efficiency 46.2%; Average dirty card pump detection period 42 days before test, day production fluid 37t/d, submergence 135m after test, pump efficiency 47.5%, it is normal that merit figure shows operating mode, and when ground does not drip liquid boiler compound, the phase of being excused from a college course reaches 260 days; On January 18th, 2014 tests the diameter adaptive plunger anti-scaling card oil well pumps such as this oilfield pumping well at apricot 6-30-SE14 well, this well test production fluid 56t/d day before yesterday, submergence 210m, pump efficiency 51.4%; Average dirty card pump detection period 35 days before test, day production fluid 58t/d, submergence 195m after test, pump efficiency 52.6%, it is normal that merit figure shows operating mode, and when ground does not drip liquid boiler compound, the phase of being excused from a college course reaches 255 days.
