Abstract

A vibration assisted well drilling simulation device comprises a frame, a column, a servo motor, a rock clamping deivce, lead screw and nut mechanisms, a drill bit, a bearing plate, a loading plate, a rotating motor, a vibration excitation table, a four-side square framework and an impact rod. The clamping deivce is arranged on a base plate of the frame, and the servo motor is arranged at the bottom of the base plate. The lead screw and nut mechanisms are symmetrically arranged on two sides of the clamping deivce, the lower ends of lead screws penetrate through the base plate of the frame and are connected with gears disposed on a motor shaft of the servo motor through gears disposed on the lead screws and synchronous cog belts, the upper ends of the lead screws sequentially penetrate through the bearing plate and the loading plate, and nuts are fixed on the loading plate. The drill bit is arranged at the bottom of the bearing plate disposed above the rock clamping device, and the rotating motor drives and is connected with the drill bit. The vibration excitation table moves vertically through matching of an outer side guide rail and an inner side guide rail. The four-side square framework is vertical and surrounds the vibration excitation table, and the impact rod is vertically arranged at the bottom of the four-side square framework. The vibration assisted well drilling simulation device is ingenious in concept, simple in structure and high in well drilling efficiency, and greatly improves well drilling speed.

Description

technical field [0001] The invention relates to a vibration-assisted drilling simulation device, which is suitable for studying the change of rock characteristics and the influence of vibration on the rock-breaking ability of a drill bit under the conditions of low-frequency large-amplitude and high-frequency small-amplitude respectively, and belongs to the technical field of resonance drilling rock-breaking. Background technique [0002] Vibration phenomena widely exist in various material media, such as metallic materials (steel, aluminum, various non-ferrous metals) and non-metallic materials (rocks, ceramics, glass, cement) and so on. The rock vibration excitation simulation test system is a test system including vibration excitation simulation and test analysis. The system can be used to analyze the vibration characteristics of various materials. [0003] Its main functions mainly include two aspects: one is to make the rock generate various excitation signals, such as...
