The invention discloses an indoor comprehensive simulation device for particle percussion drilling. The indoor comprehensive simulation device comprises a top rotating device, a gantry fixed guide rail bracket device and a hydraulic cylinder, wherein the gantry fixed guide rail bracket device comprises a bracket, a support sleeve and an ambient pressure cylinder; the ambient pressure cylinder comprises a cylinder barrel and a cylinder cover; guide rails are mounted on the bracket; the cylinder barrel is mounted on the bracket through sliding blocks matched with the guide rails; the hydraulic cylinder is connected to the bottom of the cylinder barrel for driving the cylinder barrel to slide on the guide rails; an electromagnetic valve and a pressure sensor for detecting the pressure inside the cylinder barrel are mounted on the cylinder barrel, the electromagnetic valve is connected to the pressure sensor, and the electromagnetic valve is used for opening for pressure relief when the pressure detected by the pressure sensor is greater than a preset value; the top rotating device comprises a shell, a plurality of hydraulic motors and a hollow shaft. Through the synthesis of rotation, moving and ambient pressure manufacturing for the indoor synthesis simulation device for particle percussion drilling disclosed by the invention, underground conditions can be relatively truly reflected, and the overall process of particle drilling is comprehensively simulated to obtain reliable experimental data.
Description
technical field [0001] The invention relates to the field of equipment for particle impact drilling, in particular to an indoor comprehensive simulation device for particle impact drilling. Background technique [0002] With the development of industrial technology, the demand for oil and gas resources in various countries continues to increase. However, with the continuous depletion of shallow oil and gas resources, the search for new oil and gas resources is concentrated in deep formations and complex geological conditions. At present, deep and ultra-deep wells in hard formations generally have problems such as slow speed, long period, and high cost. [0003] According to statistics, when drilling deep and ultra-deep wells, hard formations and highly abrasive footage account for 20% of the total well footage, but drilling costs account for 70% of the total cost. Therefore, it is imperative to study new efficient drilling methods for deep and ultra-deep wells in difficult-...
