Specific embodiment
Embodiment 1:
As shown in Figure 1, the present invention devises a kind of pre- fouling antiscale tube pump combination unit, including it is sequentially connected from top to bottom
Long-plunger antiscale pump 1, tail pipe 2, sand sediment pipe 5 and plug 6, be provided with three groups between the tail pipe 2 and sand sediment pipe 5 and replace phase
Between the pre- fouling pipe 3 and eye pipe 4 that arrange, the pre- fouling pipe 3 is internally provided with triple coil spring 7.
Pre- fouling pipe of the present invention constitutes one together with downhole components such as long-plunger antiscale pump, eye pipe, sand sediment pipes and prevents
Dirty system has ensured the normal production of oil well to greatest extent, has reduced pit shaft accident caused by fouling;It is pre- in the antiscale system
Fouling pipe and eye pipe are designed as three-level, i.e., be followed successively by from top to bottom pre- fouling pipe+eye pipe+pre- fouling pipe+eye pipe+pre- fouling pipe+
Eye pipe avoids blocking when only one pipe since fouling is serious so that maximally utilising pre- fouling pipe carries out antiscale
The case where eye pipe.
Embodiment 2:
On the basis of embodiment 1, the triple coil spring 7 is welded on the tube wall of pre- 3 bottom of fouling pipe, triple coil spring
7 are nested together and diameter is sequentially reduced.
The present invention has used for reference the principle of the pre- antiscale of surface line, by increasing the contact area with fluid, to realize in pipe
Pre- fouling, specific design is exactly to load onto triple coil spring in pre- fouling pipe, this triple coil spring diameter is sequentially reduced, and is covered one
It rises, is welded on the tube wall of oil pipe bottom, when oil stream is by wherein, plays and increase oil stream contact area, the effect of pre- fouling, most
Limits protect the oil well pump of top.
Embodiment 3:
On the basis of embodiment 1, as shown in Fig. 2, the long-plunger antiscale pump 1 includes at least short pump barrel 8 and pump barrel
Expansion link 9,9 upper end of pump barrel expansion link are connect with short pump barrel 8, and fixed mounting base 12 is fixed in 9 lower end of pump barrel expansion link
On, the fixed mounting base 12 is fixedly connected on fixed bearing assembly 13, is equipped in short pump barrel 8 and pump barrel expansion link 9
Long-plunger 10, the upper end of the long-plunger 10 are connected with upward-traveling valves 15, and 10 lower end of long-plunger is connected with lower travelling valve 16;It is short
Sand setting outer cylinder 11 is installed outside pump barrel 8 and pump barrel expansion link 9,11 lower end of sand setting outer cylinder is connect with duplex fitting 14, duplex fitting
14 pass through stifled 17 locking of iron;8 upper end of short pump barrel is equipped with wiper ring, and the lower end of the pump barrel expansion link 9 is provided with solid
Determine valve 18.
The length of the long-plunger 10 is greater than the length of integral barrel tubing pump.
Long-plunger antiscale pump in the antiscale system uses short pump barrel long column plug structure, when pumping pump work and stopping taking out,
One section of upward-traveling valves of long-plunger upper end does not enter short pump barrel always, so that junk, sand grains not can enter short pump barrel or in short pumps
The accumulation of nozzle portion, but by forming annular space between pump barrel expansion link outer circle and sand setting pipe orifice, it deposits under duplex fitting
The heavy dirty tail pipe of sand setting in, therefore junk, sand grains card buried column plug and blocking fixed valve and junk pad can be effectively prevent to live valve ball
The phenomenon that causing leakage, improves pump efficiency, pump detection period is extended, and short pump barrel upper end end devises wiper ring, in fouling
When plunger generates fouling in oil well, the dirt shovel on plunger can be wiped off by wiper ring, it is stuck to can effectively prevent plunger, avoids
Fouling, shake out caused by failure of pump.
In use, 10 upper end of long-plunger is connect with sucker rod, when upstroke, rod string pulls up long-plunger 10, column
Upward-traveling valves 15 and lower travelling valve 16 beyond the Great Wall are closed by head of liquid in oil pipe, at this point, the lower pump chamber below long-plunger 10
Volume increases, and pump pressure reduces, and fixed valve 18 is descended under pressure difference operation on it and opened, in crude oil suction pump, at the same time, such as
It is gradually full of by liquid in fruit oil pipe, the liquid above plunger is discharged to ground along oil pipe.So upstroke is sucking in pump
Liquid, and the process of well head discharge liquid.
When down stroke, rod string drives long-plunger 10 to move downward, long-plunger 10 compress fixed valve 18 and travelling valve it
Between liquid.When pump pressure, which increases to, is greater than pump pump intake pressure, fixed valve 18 is first closed, and is greater than when pump pressure increases to
When the above fluid pressure of plunger, travelling valve 18 is opened, and the liquid below plunger enters plunger upper part by travelling valve, arranges pump
Liquid out.So down stroke is to pump the process of the drain into oil pipe, causing the condition of pump discharge liquid is that pump pressure is higher than column
Fill in the above head of liquid.
