Problems solved by technology

However, this method is only suitable for hard cores. For loose cores (such as sandy soil cores or clay cores), due to their loose characteristics, cutting machines cannot be used to cut longitudinally, so it is difficult to form slices for preservation.

Embodiment 1

[0150] Embodiment one (as Figure 11 shown)

[0151] Figure 11 A method for preparing a clay core slice sample or a sandy soil core slice sample when the slice thickness is less than or equal to a preset thickness is shown:

[0152] Step S102, using two semi-cylindrical tubes to wrap the loose core out of the well to obtain a cylindrical core, wherein the loose core is a clay core;

[0153] Step S104, cutting along the longitudinal section of the cylindrical core to obtain a loose core with a section, and putting the core into a core box;

[0154] Step S20, drying the loose rock core (wherein, the loose rock core is placed in a cool place to dry naturally, and the room temperature is preferably kept between 15°C-30°C, generally 5-10 days is appropriate, and it can be seen from the surroundings of the rock core that the core already dry, keep the core label);

[0155] Step S302, modifying and smoothing the section of the loose core, and cleaning the corner debris;

Abstract

The invention provides a loose rock core slice specimen and a manufacture method thereof. The manufacture method of the loose rock core slice specimen includes the steps: S20 drying a loose rock core;S30 filling the dried loose rock core with glue, and curing the loose rock core to form a slice; S50 filling the slice with glue, and embedding the slice into a cured transparent glue layer to obtainthe loose rock core slice specimen. The dried loose rock core and the slice are filled with transparent resin glue in the step S30 and the step S50. According to the method, the dried loose rock coreis repeatedly filled with the glue, so that the loose clay rock core forms the slice specimen, the loose rock core needing to be preserved is completely sealed into the transparent resin glue by theprepared slice specimen and cannot be affected by the temperature and the humidity of outside environments and human factors, physical and chemical properties are invariant, and long-term preservationis facilitated.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a method for making a loose core slice sample and a loose core slice sample. Background technique [0002] In the existing field of geological drilling and coring, after the core is taken out from the bottom of the well, it is generally cut into thin slices by a cutting machine, and then stored. However, this method is only applicable to hard cores. For loose cores (such as sandy soil cores or clay cores), due to their loose characteristics, cutting machines cannot be used to cut longitudinally, so it is difficult to form slices for preservation. As the water slowly volatilizes, the clay core will crack and lose important information such as its structure and structure; as the water slowly volatilizes, the sand core will gradually become loose sand grains and lose its structure and structure information . Therefore, how to slice and seal loose cores such as clay ...
