Abstract

The invention provides a composite material sucker rod repair die and an application method thereof. The composite material sucker rod repair die comprises a die body. The die body is composed of an upper die body and a lower die body. The upper die body and the lower die body are hinged and are opened and closed relatively. The die body is internally provided with a cavity for accommodating a sucker rod. A glue injection port is formed in the top of the die body, and two ends of the die body are provided with sealing ports sealed to the outer wall of the sucker rod. The composite material sucker rod repair die can be used for repairing the composite material continuous sucker rod with eccentric wear and bump, so that the wear resistance and impact resistance of a repaired part of the sucker rod are improved, the service life of the composite material continuous sucker rod is prolonged, and the production cost is saved.

Description

technical field [0001] The invention belongs to the technical field of oil exploitation equipment, and in particular relates to a composite material sucker rod repair mold and a use method thereof. Background technique [0002] With the development of more and more complex types of reservoirs, the continuous increase of well depth and the continuous deterioration of the well and mine environment, the corrosion and eccentric wear of sucker rods have become urgent problems to be solved in oil production technology. Due to the characteristics of light weight, high strength and corrosion resistance of composite sucker rods, composite sucker rods have begun to gradually replace traditional metal sucker rods. [0003] With the increasing application of composite material sucker rods, partial wear and bumping of the rod body are inevitable. Since the composite sucker rod cannot continue to be used under the condition of eccentric wear and bumping, it will cause great waste. Theref...
