Abstract

The invention discloses an automatic threaded fastener loosening system of drilling tools, a use method thereof and a microcontroller. The automatic threaded fastener loosening system is used for achieving the effect of automatically switching drilling tools, and comprises a hydraulic solenoid valve, a hydraulic fastener loosening oil cylinder, an upper clamping oil cylinder, a lower clamping oil cylinder, a microcontroller, electromagnetic coils, a pressure sensor and a position sensor. The upper clamping oil cylinder is used for clamping or loosening the male fastener end of an upper drill rod, and the lower clamping oil cylinder is used for clamping or loosening the female fastener end of a lower drill rod. The hydraulic fastener loosening oil cylinder is used for loosening the upper drill rod clamped by the upper clamping oil cylinder. The microcontroller is used for controlling the upper clamping oil cylinder and the hydraulic fastener loosening oil cylinder to stretch and contract according to monitoring of the pressure sensor and the position sensor so as to finish loosening or mounting of connector threaded fasteners of the upper drill rod and the lower drill rod of the drill tools. The automatic threaded fastener loosening system of the drilling tools, the use method thereof and the microcontroller achieve the effect of automatically switching the drilling tools quickly, safely, reliably and conveniently, reduce the labor intensity of the working staff and improve the drilling efficiency.

Description

technical field [0001] The invention relates to the technical field of petroleum geophysical drilling rigs, in particular to an automatic rubbing system for drilling tools of a drilling rig, a method for using the same, and a microcontroller. Background technique [0002] Drilling rigs are widely used in oil and natural gas mining fields. When working, geophysical drilling rigs drive drilling tools to break rocks, drill underground, and drill holes of specified depth for oil or gas extraction machines to obtain oil or natural gas. The drilling tool of a general geophysical drilling rig is composed of many joints of drill pipes. The specific number of joints selected is determined according to the drilling depth. One end of each joint of drill pipe has a box end, and the other end has a pin end. Then, when specifically connecting the above-mentioned two sections of drill pipes, the male end of one section is connected with the female end of the other section. In actual work,...
