Fretsaw cutting device for rock core samples and cutting method therefor

Abstract

The invention relates to a fretsaw cutting device for rock core samples and a cutting method therefor. The transmission integration mechanism of the fretsaw cutting device is arranged at the upper endof a supporting frame, and is provided with an emery wire winder, an emery wire motion adjuster, a transverse motion adjusting button, a circular motion adjusting button and an adjusting wrench. A rotating platform is consisting of an upper rotating platform and a lower rotating platform, and is arranged between the transmission integration mechanism and the supporting tray of the supporting frame, the upper rotating platform and the lower rotating platform are provided with clamping devices. The rock core sample is fixed between the two clamping devices, the upper rotating platform and the lower rotating platform are provided with transverse motion guide rails, each transverse motion guide rail is provided with an emery wire moving device, wherein the two emery wire moving devices are located on the same vertical line, and an emery wire moves up and down between the two emery wire moving devices. According to the fretsaw cutting device for rock core samples and the cutting method therefor, problem of damages to the pore throat structure of a rock body caused by the fracture of a fragile rock core sample during rotary drilling and coring is solved, and the original pore structureof the rock is retained to the maximum extent.

Description

Technical field: [0001] The invention relates to the preparation of rock core samples for industrial micro / nano CT scanning, in particular to a wire saw cutting device for rock core samples and a cutting method thereof. Background technique: [0002] The preparation of core samples is an important reference index for the accuracy of industrial micro / nano CT scans. The focus of core sample preparation is the size of the core sample diameter and the degree of damage to the rock sample itself during the core sample preparation process, which directly It is related to the precision and accuracy of industrial micro / nano CT core sample scanning. Theoretically, the smaller the diameter of the core sample, the higher the scanning accuracy of the industrial micro / nano CT core sample; the smaller the damage of the core sample during the preparation process, the more realistic the scanning of the industrial micro / nano CT core sample can be. It reflects the physical properties of the r...
