Abstract

The invention discloses a driving type hydraulic oscillator for well drilling. The driving type hydraulic oscillator comprises an upper shell and a lower shell, wherein a shaft sleeve is fixedly arranged at the top of the upper shell; a cleaning shaft fixedly penetrates through the shaft sleeve; a handle block is connected to the top end of the cleaning shaft; a cleaning rod is mounted at the bottom of the cleaning shaft; a cleaning brush is connected to the cleaning rod; an anti-collision mechanism is fixedly mounted at the bottom end of the cleaning shaft; and a cleaning mechanism is arranged on the outer top wall of the upper shell. According to the driving type hydraulic oscillator, the handle block is held by a hand to pull the upper shell, then the cleaning shaft is driven to move upand down, the cleaning rod moves up and down to drive the cleaning brush to move, and then the lower shell is cleaned.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a driven hydraulic oscillator for drilling. Background technique [0002] Drilling is the project of using mechanical equipment to drill the formation into cylindrical holes with a certain depth. According to the way of rock breaking and the type of tools used, it can be divided into sudden drilling and rotary drilling; in geological work, drilling equipment is used to drill a cylindrical hole with a small diameter and a large depth underground. Also known as drilling. The diameter and depth of the well depends on the purpose of the well and the burial depth of the minerals. The study found that when the mud passes through the drilling tool, the pressure change of the mud will cause the vibration of the drilling tool, so that the static friction of the drilling tool against the well wall becomes dynamic friction, which effectively reduces the friction resistance, thereby achie...
