Abstract
The utility model provides a kind of screw pump suitable for glutenite stratum, is related to oil tool research field.A kind of screw pump suitable for glutenite stratum described in utility model includes lower contact, spacer pin, stator, rotor, top connection, sand stop cover, sucker rod.The lower contact is connected with oil pipe respectively with top connection, and screw pump is fixed in whole flow string.Rotor is connected with sucker rod.Sucker rod rotor driven is rotated in stator, and crude oil is transported into top.Described rotor one end is located in spacer pin, plays a part of limitation rotor motion space, it is ensured that effective cooperation of rotor and stator.The spacer pin lower end is provided with the fragmented rock particle being mixed with sand stop cover, crude oil and stopped by sand stop cover, it is impossible to enter screw pump.The utility model can will not enter screw pump, reduce the abrasion and destruction of screw pump, so as to extend the use time of screw pump, it is ensured that the normal production in oil field by fragmented rock particulate blockage outside sand stop cover.
Description
Technical field
The utility model is related to oil tool research field, more particularly to a kind of screw pump suitable for glutenite stratum.
Background technology
Screw pump is that the spatial volume that engages for relying on the pump housing and screw rod to be formed changes and moves to convey liquid or be allowed to
The drum pump of supercharging.The characteristics of screw pump is flow trim, pressure fluctuation is small, have low suction capacity, noise, efficiency high, life-span
Long, reliable operation.And advantage that it is protruded does not form vortex, to the sticky insensitive of medium when being pumped (conveying) medium, can convey height
Viscous media.Therefore, screw pump is widely used on oil field.
The composition on glutenite stratum is based on glutenite, pebbly sandstone and psephitic sandstone, and formation cementation intensity is very low.With
The progress of oil field production, producing pressure differential constantly increases, and rock occurs to crush, and fragmented rock particle enters screw pump, and abrasion turns
Son, damages screw pump, and what interference oil field was produced is normally carried out.Accordingly, it is desirable to provide a kind of screw rod suitable for glutenite stratum
Pump.
Utility model content
The purpose of this utility model is to provide a kind of screw pump suitable for glutenite stratum, and it can prevent glutenite
The rock particles of stratum crushing enters screw pump, so that protection oil production equipment is played, the effect increased the service life.
A kind of screw pump suitable for glutenite stratum described in utility model includes lower contact, spacer pin, stator, turned
Son, top connection, sand stop cover, sucker rod.
The lower contact is connected with oil pipe respectively with top connection, and screw pump is fixed in whole flow string.Rotor with
Sucker rod is connected.Sucker rod rotor driven is rotated in stator, and crude oil is transported into top.Described rotor one end is located at spacer pin
It is interior, play a part of limitation rotor motion space, it is ensured that effective cooperation of rotor and stator.
The spacer pin lower end is provided with the fragmented rock particle being mixed with sand stop cover, crude oil and stopped by sand stop cover, it is impossible to
Into screw pump.The sand stop cover is provided with oil flow hole, and crude oil can enter screw pump by oil flow hole.
It is preferred that, the rotor is formed by steel alloy by smart car, chromium plating and polishing.
It is preferred that, the top connection length is 10 centimetres.
It is preferred that, the lower contact length is 15 centimetres.
The characteristics of the utility model and advantage are：
The utility model uses above technical scheme so that during screw rod pump work, the rock particles of stratum crushing is blocked
Outside sand stop cover, screw pump will not be entered, reduce the abrasion and destruction of screw pump, so that extend the use time of screw pump,
Ensure the normal production in oil field.
Brief description of the drawings
The following drawings is only intended to, in doing utility model schematic illustration and explanation, not limit model of the present utility model
Enclose.
A kind of structural representation for screw pump suitable for glutenite stratum that Fig. 1 provides for the utility model.
In figure：1- sucker rods, 2- top connections, 3- rotors, 4- stators, 5- spacer pins, 6- sand stop covers, 7- lower contacts.
Embodiment
Illustrate specific embodiment of the present utility model below in conjunction with the accompanying drawings.The utility model is related to a kind of suitable for gravel
The screw pump on rock stratum, including sucker rod 1, top connection 2, rotor 3, stator 4, spacer pin 5, sand stop cover 6, lower contact 7.
The lower contact 7 is connected with oil pipe respectively with top connection 2, and screw pump is fixed in whole flow string.Rotor 3
It is connected with sucker rod 1.The rotor driven 3 of sucker rod 1 is rotated in stator 4, and crude oil is transported into top.Described one end of rotor 3 is located at
In spacer pin 5, play a part of limiting the space of rotor 3, it is ensured that effective cooperation of rotor 3 and stator 4.
The lower end of spacer pin 5 is provided with the fragmented rock particle being mixed with sand stop cover 6, crude oil and stopped by sand stop cover 6, no
Screw pump can be entered.The sand stop cover 6 is provided with oil flow hole, and crude oil can enter screw pump by oil flow hole.
It is preferred that, the rotor 3 is formed by steel alloy by smart car, chromium plating and polishing.
It is preferred that, the length of top connection 2 is 10 centimetres.
It is preferred that, the length of lower contact 7 is 15 centimetres.
Finally it should be noted that：Various embodiments above is only limited to illustrate the technical solution of the utility model, rather than to it
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
