Drill rod rust removal equipment for petroleum engineering

Abstract

The drill rod rust removal equipment for petroleum engineering comprises a support, and a mounting cylinder, a driving mechanism, a conveying mechanism, a cleaning mechanism and a spraying mechanism are arranged on the support; a polishing piece and a smearing piece are arranged on the inner wall of the mounting cylinder; the cleaning mechanism comprises a first shell which is installed on the support and rotationally arranged on the installation cylinder in a sleeving mode and a dust collector communicating with the interior of the first shell. The installation cylinder is provided with a vent groove communicating with the interior of the installation cylinder and the interior of the first shell. The spraying mechanism comprises two second shells which are installed on the support and rotationally arranged on the installation cylinder in a sleeving mode, an oil tank containing lubricating oil and an oil pump installed on the oil tank, and a plurality of oil holes communicating with the interior of the installation cylinder and the interiors of the second shells are formed in the installation cylinder. The oil pump communicates with the interior of the oil tank and communicates with the interior of one second shell through an oil outlet pipe, and the other second shell communicates with the interior of the oil tank through an oil inlet pipe. The rust removal and rust prevention treatment of the drill rod can be facilitated.

Description

technical field [0001] The present application relates to the technical field of petroleum engineering, and in particular, to a rust removal device for drill pipes used in petroleum engineering. Background technique [0002] Petroleum engineering is a general term for a series of engineering and process technologies implemented to establish suitable flow channels and optimize lifting methods according to the characteristics of oil and gas and reservoirs, and to economically and efficiently extract deeply buried oil and gas from oil and gas reservoirs to the surface, including Reservoir, drilling, oil production and oil surface engineering, etc. Petroleum engineering is a comprehensive engineering that integrates various process technologies and engineering measures, and multi-process technologies cooperate with each other, penetrate each other, promote and develop each other. Oil is generally mined underground, and drill pipes are used in the process of mining. Dirt and rust...

Problems solved by technology

[0003] One of the existing methods for derusting drill pipes is manual grinding, which is not only time-consuming and laborious, but also unevenly polished, which aggravates the wear of the drill pipe. The other is equipment grinding, which makes the drill pipe rotate by itself. It is easy to be dangerous when rotating, and the rotating speed is slow, and the grinding is not thorough; in addition, manual application of lubricating oil to prevent rust is not only easy to apply unevenly, but also easy to cause waste of lubricating oil, so it needs to be improved
