Shale rock core box

Abstract

The invention provides a shale rock core box, and relates to the technical field of rock core storage and transportation. The shale rock core box comprises a box body and a partition plate, and the partition plate divides the box body into at least two rock core containing grooves; rock core supporting pieces which extend to the top of the box body are arranged at the groove bottoms of the rock core containing grooves, the top surfaces of the rock core supporting pieces are arranged to be arc-shaped surfaces, the rock core supporting pieces are used for supporting rock cores placed in the rockcore containing grooves so as to enable the rock cores to be far away from the groove bottoms of the rock core containing grooves to prevent the situation that the rock cores are directly in contactwith the groove bottoms and then can be soaked by accumulated water; and the curvature radius of each arc-shaped surface is larger than or equal to the curvature radius of each rock core so that an operator can conveniently turn over the rock cores placed on the rock core supporting pieces, and the problems that in the prior art, degeneration and efficacy loss of the rock cores are caused due to the fact that the shale rock core box is prone to water accumulation, and the rock cores cannot be conveniently turned over are solved.

Description

technical field [0001] The invention relates to the technical field of core storage and transportation, in particular to a shale core box. Background technique [0002] Shale gas refers to unconventional natural gas that occurs in organic-rich shale reservoir rock series and its interlayers, mainly in adsorption and free states. Its main component is methane, which is a clean and efficient energy source. and chemical raw materials. Compared with conventional natural gas, shale gas has the advantages of long mining life and long production cycle, and has high industrial economic value. [0003] In the preliminary exploration of shale gas, many scientific researches are inseparable from core flow experiments. The test object of the core flow experiment is the core, and the core is a cylindrical rock sample taken out by using a core ring drill bit and other coring tools. It is an important physical material for studying geological and mineral conditions. After the core is ta...
