Compression type packer for oil exploitation

Abstract

The invention discloses a compression type packer for oil exploitation, and relates to the technical field of oil exploitation tools. The compression type packer for oil exploitation comprises a compression type packer body, and connecting pipes are fixedly connected with the upper end and the lower end of the compression type packer body. According to the compression type packer for oil exploitation, through cooperation of the compression type packer body, a protection device and the connecting pipes, and the problem that the outer wall of the compression type packer body is abraded when the compression type packer body moves in an oil well is effectively solved through the sleeving connection relation between the protection device and the compression type packer body; and the protection device is installed so that the inner wall of the oil well can make direct contact with the compression type packer body, abrasion of the inner wall of the oil well to the outer wall of the compression type packer body is avoided, damage to the compression type packer body is reduced, the service life of the compression type packer body is prolonged, the cost for replacing and maintaining the compression type packer body is reduced, and the oil exploitation cost of a factory is reduced.

Description

technical field [0001] The invention relates to the technical field of oil extraction tools, in particular to a compression packer for oil extraction. Background technique [0002] Petroleum is a fluid mineral buried deep in the ground. At first, people called oily liquid minerals produced in nature petroleum, combustible gas natural gas, and solid combustible fuel minerals as asphalt. With the deepening of mineral research, they realized that they are composed of All of them belong to hydrocarbon compounds, which are related to each other in origin, so they are collectively referred to as petroleum. Petroleum plays an important role in the national economy. Compared with coal, it has high energy density, convenient transportation and storage, and pollution after combustion. The fuel oil extracted from petroleum is the main fuel for various kilns in transportation, power plant boilers, metallurgical industry and building material industry. Liquefied petroleum gas and pipelin...

AI Technical Summary

Problems solved by technology

[0003] However, the existing compression packer rubs against the inner wall of the oil well during the movement of the oil well, and the inner wall of the oil well is easy to wear the outer wall of the compression packer, and long-term wear will lead to the use of the packer. The reduction of service life will increase the cost of replacing the packer; the existing packer will collide with the transport box due to the influence of road conditions during transportation, which will accelerate the damage of the packer
