Embodiment
[0038] Please refer to Figure 1 to Figure 6 , the present embodiment provides a core sample holder, comprising:
[0039] The housing 10 has an accommodating chamber 11 inside the housing 10, and the accommodating chamber 11 has an opening;
[0040]The envelope assembly, the envelope assembly includes an envelope section and a fixing ring 24, the envelope section is used to envelope the core sample 1000, and two adjacent envelope sections are connected by the fixing ring 24, the envelope assembly is arranged in the housing chamber 11 and the envelope section is connected to the shell There is a distance between the inner walls of 10, and part or all of the fixing ring 24 is used to connect the pressure measuring pipeline 1001 or the temperature measuring probe;
[0041] The cover assembly 30 is used for sealing the opening.
[0042] Wherein, the housing 10 is cylindrical, and furthermore, the accommodating chamber 11 of the housing 10 is a cylindrical chamber, which is condu...

The invention provides a core sample holder, and relates to the technical field of sample holding devices. The core sample holder includes a shell, an enveloping assembly and a capping assembly, wherein the shell is internally provided with an accommodating cavity with an opening; the enveloping assembly includes enveloping sections and fixing rings, the enveloping sections are used for envelopingcore samples, the adjacent two enveloping sections are connected through the fixing rings, the enveloping assembly is arranged in the accommodating cavity, and a space is arranged between the enveloping sections and the inner wall of the shell; part or all of the fixing ringsare used for connecting a pressure measurement pipeline or a temperature measurement probe; and the capping assembly is used for sealing the opening. According to the core sample holder, the defect that existing rubber cylinders are not resistant to carbon dioxide corrosion is overcome from the material and structure, theseal failure of the enveloping sections cannot be caused by being corroded by carbon dioxide in a displacement experiment, and reliable test points assist in data acquisition, so that the core sampleholder is very practical.
Description
technical field [0001] The present invention relates to the technical field of sample holding devices, in particular to a rock core sample holding device. Background technique [0002] In the current core displacement experiment, the core sample holder structure used is to first install the sample in a thick-walled rubber tube of the holder. In order to prevent leakage at the edge of the rubber tube containing the sample, a static confining pressure is applied to the annular space between the core sample holder shell and the outer wall of the rubber sleeve. [0003] In this structure, the rubber tube used is generally cast from nitrile or fluorine rubber material. When making measuring points on the cylinder body, due to the problem of the materials used, when it comes to CO 2 Seal failure is prone to occur in the displacement use. Contents of the invention [0004] The object of the present invention is to provide a rock core sample holder, which can ensure a good clam...
