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 twisting 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 the fields of oil and natural gas extraction. When working, the geophysical drilling rig drives the drilling tool to break the rock, drill into the ground, and drill a wellbore with a specified depth for the oil or gas extraction machine to obtain oil or natural gas. The drilling tool of a general geophysical drilling rig is composed of many sections of drill pipes. The specific number of sections to be selected is determined according to the depth of drilling. One end of each section of drill pipe has a female buckle end, and the other end has a male buckle end. Then, when connecting two sections of the above drill pipes, the male end of one section is connected to the fem...
