Abstract
The utility model discloses an underground screw pump special for an oil field. The problem that the existing screw pump is low in wear resistance, low in corrosion resistance and low in high-temperature resistance is mainly solved. The underground screw pump is characterized in that a polytetrafluoroethylene layer (2) is arranged in a stator (1). The underground screw pump special for the oil field has the characteristics of high wear resistance, high corrosion resistance and high high-temperature resistance.
Description
Technical field
The utility model relates to the underground bolt special pump in oil recovery field, oil field oil recovery well lifting used screw pump, especially oil field.
Background technique
In oil recovery field, oil field, screw pump is important oil recovery well lifting equipment.Screw pump is made up of stator and rotor.And the stator of existing screw pump exists wear resistance, rotproofness and heat-resisting quantity poor owing to reasons in structure, thereby causes pump detection period and screw pump shortening in working life, maintenance load to increase, and has finally increased cost for oil production, has reduced the oil recovery well benefit.
Summary of the invention
In order to solve the problem of existing screw pump wear resistance, rotproofness and heat-resisting quantity difference.The utility model provides a kind of oil field underground bolt special pump.The underground bolt special pump in this oil field has the good characteristics of wear resistance, rotproofness and heat-resisting quantity.
The technological scheme of the utility model is: the underground bolt special pump in this oil field comprises stator.Polytetrafluoroethylene floor is arranged in the stator.
Stator in the such scheme is outward a helical; Polytetrafluoroethylene floor thickness everywhere equates.
The utlity model has following beneficial effect: the underground bolt special pump in this oil field is owing to have polytetrafluoroethylene floor in the employing stator, and polytetrafluoroethylene floor thickness everywhere equates.At first owing to be built-in with polytetrafluoroethylene floor at stator; Thereby improve wear resistance, rotproofness and the heat-resisting quantity of the underground bolt special pump in this oil field, finally reach and prolong pump detection period and screw pump working life, minimizing maintenance load; Reduce cost for oil production, increase the purpose of oil recovery well benefit.Simultaneously, make the expansion coefficient of stator case keep identical, increase the intensity of stator case, finally reach and prolong pump detection period and screw pump working life owing to adopt the structure of the polytetrafluoroethylene floor of same thickness everywhere.The underground bolt special pump in this oil field has the good characteristics of wear resistance, rotproofness and heat-resisting quantity thus.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is that the utility model has outward and the rotor worm structure schematic representation that matches;
Accompanying drawing 3 be among Fig. 1 A-A to sectional drawing.
1-stator among the figure, the 2-polytetrafluoroethylene floor.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the underground bolt special pump in this oil field comprises stator 1.Have in described stator 1 can adopt and the rotor screw thread that matches, be outward cylindrical structural, all has inside and outside also can adopting and the rotor worm structure that matches.Polytetrafluoroethylene floor 2 is arranged in the stator 1; Teflon has high abrasion, high corrosion resistant and resistant to elevated temperatures characteristic, utilizes this characteristic of teflon, and then improves wear resistance, rotproofness and the heat-resisting quantity of the underground bolt special pump in this oil field; Prolong pump detection period and screw pump working life; Reduce maintenance load, reduce cost for oil production, increase the oil recovery well benefit.Polytetrafluoroethylene floor 2 thickness everywhere all equates, just waits wall thickness, and it is identical that the expansion coefficient of stator 1 housing keeps, and increases the intensity of stator 1 housing, prolongs pump detection period and screw pump working life.
Working principle is identical with existing screw pump.This pump prolongs working life greatly under identical condition.
