Abstract
The utility model relates to a sucker rod for oil production in an oil field, in particular to an upset forging direct-connected high anti-torque hollow sucker rod. The technical scheme is as follows: the upset forging direct-connected high anti-torque hollow sucker rod comprises a rod body; one end of the rod body is provided with an upset forging high anti-torque male connector, and the other end of the rod body is provided with an upset forging high anti-torque coupling; and a high temperature resistance seal ring is sleeved on the outer wall of the upset forging high anti-torque male connector. The upset forging direct-connected high anti-torque hollow sucker rod overcomes the defects that the stress on a friction weld crater is concentrated and the friction weld crater is easy to be broken, and the improvement to the oil production efficiency is reliably guaranteed; the anti-torque capability is greatly improved, and torsibility with heavier load can be borne; and the service life of the hollow sucker rod is prolonged, and the oil production cost is reduced.
Description
One, technical field
The utility model relates to a kind of sucker rod of oil field oil recovery usefulness, is the direct-connected high torque resistant hollow rod of a kind of upset forging type concretely.
Two, background technology
At present, the hollow rod of domestic oil field oil recovery usefulness mostly is the common flat button hollow stem of friction welding formula, because of its in use, have topmost two disadvantages: one, the two ends screw thread blocks easily, and the screw thread damage of colliding with easily, the situation of inextricable joint often occurs, bring very big labour intensity to the well puller, during card tight, can only adopt sawed-off method, more because of having caused hollow rod to be scrapped; Two, joint and box cupling are friction welding type with the body of rod, often occur because of friction weld bond stress is concentrated crackle, disconnected phenomenon of taking off taking place, and have brought very big difficulty to oil producing operation, have caused very big economic loss to the oil field.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provides a kind of upset forging type simple in structure, with low cost direct-connected high torque resistant hollow rod.
Its technical scheme is: it comprises the body of rod, and an end of the body of rod is provided with the high torque resistant male joint of upset forging type, and the other end of the body of rod is provided with the high torque resistant box cupling of upset forging type, and the high torque resistant male joint of upset forging type outer wall is set with high-temperature resistant seal ring.
The utility model has overcome friction weld bond place stress to be concentrated, and the situation of fracture provides reliable guarantee for the raising of oil recovery efficiency easily; Its anti-twisting property strengthens greatly, can bear the more twisting resistance of high load capacity; Prolong the application life of hollow rod, reduced cost for oil production.
Four, description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Five, the specific embodiment
As shown in the figure, the direct-connected high torque resistant hollow rod of a kind of upset forging type comprises the body of rod 3, and 3 one ends of the body of rod are provided with the high torque resistant male joint 1 of upset forging type, the other end of the body of rod 3 is provided with the high torque resistant box cupling 4 of upset forging type, and high torque resistant male joint 1 outer wall of upset forging type is set with high-temperature resistant seal ring 2.
Claims (1)
1. direct-connected high torque resistant hollow rod of upset forging type, comprise the body of rod, it is characterized in that: an end of the body of rod is provided with the high torque resistant male joint of upset forging type, and the other end of the body of rod is provided with the high torque resistant box cupling of upset forging type, and the high torque resistant male joint of upset forging type outer wall is set with high-temperature resistant seal ring.
