Between the pre- fouling pipe 3 that arranges and eye pipe 4, described pre- fouling pipe 3 is internally provided with triple coil spring 7.
Pre- fouling pipe of the present invention, constitutes one and prevents together with downhole components such as long-plunger antiscale pump, eye pipe, sand sediment pipes
Dirty system, has ensured to greatest extent the normal production of oil well, reduces the pit shaft accident that fouling is caused；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, so as to maximally utilise pre- fouling pipe antiscale is carried out, it is to avoid blocked because fouling is serious during only one of which eye pipe
The situation of eye pipe.
Embodiment 2：
On the basis of embodiment 1, described triple coil spring 7 is welded on the tube wall of the pre- bottom of fouling pipe 3, 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, is realized in pipe by increasing the contact area with fluid
Pre- fouling, specific design be exactly load onto triple coil spring in pre- fouling pipe, this triple coil spring diameter is sequentially reduced, and is enclosed within one
Rise, be welded on the tube wall of oil pipe bottom, when oil stream increases oil stream contact area by wherein, playing, 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 described long-plunger antiscale pump 1 at least includes short pump barrel 8 and pump barrel
Cylinder 9 is lengthened, described pump barrel lengthens the upper end of cylinder 9 and is connected with short pump barrel 8, and pump barrel lengthens the lower end of cylinder 9 and is fixed on fixed mounting base 12
On, described fixed mounting base 12 is fixedly connected on fixed bearing assembly 13, and short pump barrel 8 and pump barrel are lengthened and be provided with cylinder 9
Long-plunger 10, the upper end of described long-plunger 10 is connected with upward-traveling valves 15, and the lower end of long-plunger 10 is connected with lower travelling valve 16；It is short
Pump barrel 8 and pump barrel to be lengthened and be provided with sand setting outer tube 11 outside cylinder 9, and the lower end of sand setting outer tube 11 is connected with duplex fitting 14, duplex fitting
