Problems solved by technology

[0003] The prior art has the following deficiencies: when the oil rod centralizer in the prior art is in use, although it can support the mandrel and reduce wear and tear, the oil rod centralizer in the prior art can be disassembled and installed during use. Both are troublesome. It takes a lot of time to install the oil rod centralizer before using the oil rod centralizer. At the same time, it takes a long time to disassemble the oil rod centralizer after the user is finished, resulting in the work efficiency of the mandrel. Reduced, inconvenient for users to use

Abstract

The invention discloses a quick-disassembling and quick-replacing sucker rod centralizer and method. The quick-disassembling and quick-replacing sucker rod centralizer comprises a first semi-circularplate and a second semi-circular plate, an auxiliary mechanism is arranged in the first semi-circular plate and the second semi-circular plate, and the auxiliary mechanism extends out of the first semi-circular plate and the second semi-circular plate; the auxiliary mechanism comprises six clamping plates, the six clamping plates are all arranged in the first semi-circular plate and the second semi-circular plate, the six clamping plates are combined into a hollow cylinder, and clamping assemblies are arranged on the six clamping plates. The quick-disassembling and quick-replacing sucker rod centralizer has the beneficial effects that the auxiliary mechanism is designed, so that the first semi-circular plate and the second semi-circular plate can be rapidly disassembled and assembled; andmeanwhile, the six clamping plates are extremely convenient to disassemble and assemble, installation can be directly carried out outside the axis, the assembling and disassembling time of the suckerrod centralizer is shortened, the normal working efficiency of the axis is guaranteed, and a user can conveniently use the sucker rod centralizer.

Description

technical field [0001] The invention relates to the field of oil extraction equipment, in particular to a quick-release and quick-change sucker rod centralizer and method. Background technique [0002] The sucker rod centralizer is an anti-eccentric downhole tool for pumping wells. It is suitable for pumping wells with eccentric wear, especially for pumping wells and directional deviated wells with eccentric wear above the neutral point of the sucker rod. The neutral point of the sucker rod Below, it cooperates with the nylon centralizer on the sucker rod body to prevent partial wear. The sucker rod moves up and down in the oil pipe. Due to the elastic deformation of the sucker rod, the rod and the wall of the oil pipe are prone to friction, and the sucker rod is easy to Broken off, the sucker rod centralizer has strong flexibility, it contacts with the inner wall of the oil pipe, can reduce the friction between the rod and the pipe, and enhance the oil production life of th...
