Multi-angle anisotropic medium experimental rock sample drilling device

Abstract

The invention discloses a multi-angle anisotropic medium experiment rock sample drilling device. The device comprises a drilling machine base, a supporting assembly, a drill bit assembly, a power assembly, a lubricating assembly and a clamping assembly. The supporting assembly and the clamping assembly are arranged on the drilling machine base, and the power assembly is arranged at the upper end of the supporting assembly; the drill bit assembly is connected with the power assembly; the lubricating assembly comprises a lubricant box, the drill bit assembly comprises a drill bit power transmission shaft and a hollow sampling drill bit, the drill bit power transmission shaft is a hollow shaft, and the top of the drill bit power transmission shaft communicates with a lubricant control switch;the drill bit power transmission shaft is driven by the power assembly to rotate; and the hollow sampling drill bit is arranged at the lower end of the drill bit power transmission shaft, and the interior of the hollow sampling drill bit communicates with an inner cavity of the drill bit power transmission shaft. Lubricant in the lubricant box above a drilling machine is transferred into the drill bit through the hollow power transmission shaft, internal lubrication is achieved, and corresponding lubricant can be used for different lithologic rock samples.

Description

technical field [0001] The invention relates to the technical field of mechanical processing for rock physics experiments in geological exploration, in particular to a multi-angle drilling device for anisotropic medium experiment rock samples. Background technique [0002] At present, the known experimental rock core drilling device is to install a hollow sampling drill bit on the existing bench-top drilling machine for sampling, and the full-diameter holder is a flat plate vise without radian, and the contact area between the full-diameter rock core and the holder is small. The full-diameter core is easy to slide when drilling samples, which affects the success rate of drilling samples. Only rock samples perpendicular to the axis of the full-diameter core can be drilled, that is, samples taken in parallel to the full-diameter direction. Through literature search and investigation, it is found that the reservoir rocks in many basins have obvious anisotropic characteristics,...

Problems solved by technology

[0004] In order to solve the problems of polluting the working environment by directly showering the drill bit with tap water, single sampling angle, and insufficient clamping stability, the present invention provides a multi-angle drilling device for anisotropic medium experimental rock samples, which can add corresponding lubrication for different lithologies Liquid, to achieve internal lubrication sampling, not only to achieve multi-angle sampling, improve the success rate of sampling, but also make the rock sample drilling environment clean and tidy
