Abstract
A high strength water distributor mainly solves the problem of low strength of existing water distributor and poor corrosion resistance. It features in that a central tube (2) is made of stainless steel, after the central tube (2) is connected with a lower joint via screw thread, its lower end is then welded and fixed. The water distributor has the advantages of high strength and good corrosion resistance.
Description
Technical field
The utility model relates to the used injection well downhole flow regulator of a kind of water injection well in oil fields, especially high strength injection well downhole flow regulator.
Background technology
The oil recovery field in the oil field, in order to improve recovery ratio, need be with injection well downhole flow regulator water filling in water injection well.Intensity is hanged down and the problem of corrosion-resistant and existing injection well downhole flow regulator is because reasons in structure exists, thereby reduces application life, influences water-injection efficiency.
Summary of the invention
Existing injection well downhole flow regulator intensity is hanged down and the problem of corrosion-resistant in order to solve.The utility model provides a kind of high strength injection well downhole flow regulator.This high strength injection well downhole flow regulator has the characteristics of intensity height and good corrosion resistance.
The technical scheme of the utility model is: this high strength injection well downhole flow regulator comprises lower contact and central tube.Central tube is a stainless steel, and after central tube passed through screw thread and lower contact is connected, the lower surface was welded fixing again.
The utlity model has following beneficial effect: this high strength injection well downhole flow regulator is because the employing central tube is a stainless steel, and central tube is through screw thread and after lower contact was connected, the lower surface was welded fixing structure again.Utilize stainless steel to improve corrosion resistance, increase the service life, utilize screw thread with central tube and lower contact align be connected after, the lower surface is welded fixing again, and then the raising bonding strength, increases the service life.This high strength injection well downhole flow regulator has the characteristics of intensity height and good corrosion resistance thus.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-lower contact among the figure, the 2-central tube.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing, this high strength injection well downhole flow regulator comprises lower contact 1 and central tube 2.Central tube 2 is the stainless steel of 1Cr18Ni9Ti, because central tube 2 adopts stainless steels, thereby improves the corrosion resistance of central tube 2, prolongs this high strength injection well downhole flow regulator application life.With after lower contact 1 is connected, the lower surface is welded fixing again through screw thread for central tube 2, by screw thread central tube 2 is aligned with lower contact 1 to be connected, and the lower surface is welded fixingly more then, and then raising bonding strength prolongs this high strength injection well downhole flow regulator application life.Tensile strength can reach more than 45 tons because of it welds fixedly, thereby guarantees that fully this high strength injection well downhole flow regulator can better adapt to and bear water injection string down-hole pulling force.
Claims (1)
1. a high strength injection well downhole flow regulator comprises lower contact (1) and central tube (2), it is characterized in that: central tube (2) is a stainless steel, and after central tube (2) passed through screw thread and lower contact (1) is connected, the lower surface was welded fixing again.
