Abstract

The invention discloses a field sandy mudstone identification device and method. The device comprises a hollow cylinder extending in the axial direction; a grinding portion used for grinding a rock sample, wherein the grinding portion is provided with a grinding surface used for making contact with the rock sample, the grinding surface being located outside the cylinder body when the rock sample is ground; a vibration pressure sensor connected with the grinding portion and used for acquiring pressure and vibration frequency of the grinding surface; and a water adding portion arranged on the cylinder body and used for adding water to the grinding surface. The field sandy mudstone identification device and method provided by the invention can objectively and quantitatively evaluate the lithology of the rock and provide accurate basis for subsequent research.

Description

technical field [0001] The present application relates to the field of abrasive jet technology, and in particular to a device and method for identifying sand and mudstone in the field. Background technique [0002] The descriptions in this section merely provide background information related to the disclosure in this application and may not constitute prior art. [0003] Field description is an important process in field geological reconnaissance, and it is also one of the important basic data sources for geological analysis. Rock grain size is one of the important field description items. According to the different grain sizes of rocks, rocks can be preliminarily divided into glutenite, sandstone, siltstone, mudstone, etc. Further subdivided by composition, there are argillaceous siltstone, silty mudstone and so on. [0004] Grain size is a microscopic concept. Usually, the particle size of sandstone is above 0.1mm, the particle size of siltstone is 0.1-0.01mm, and the ...
