A rock core clamper used for carbon dioxide corrosion tests

Abstract

A rock core clamper used for carbon dioxide corrosion tests is provided. The rock core clamper comprises a clamping cylinder formed by connecting a first half cylinder to a second half cylinder. A corrosion cavity is formed in the clamping cylinder. Two ends of the clamping cylinder are respectively provided with a first opening. The cylinder wall of the clamping cylinder is also provided with two axisymmetric second openings. The rock core clamper can perform carbon dioxide corrosion, and perform permeability tests, a rock core does not need to be taken out repeatedly in a process and all tests are completed in the rock core clamper. As the rock core is not taken out, the position of the rock core does not change, corrosion can be continued after permeability calculation is finished, thus achieving continuous value measuring, making experiment time short and saving the rock core.

Description

technical field [0001] The invention relates to a holding device, in particular to a rock core holder used in a carbon dioxide corrosion test. Background technique [0002] At present, the problem of global warming caused by a large amount of carbon dioxide emissions is becoming more and more severe, and environmental protection has attracted more and more attention from the international community. Storing carbon dioxide in exhaust gas is one of the effective ways to avoid climate change. For this reason, carbon dioxide sequestration technology emerged as the times require, and alleviated the greenhouse effect to a certain extent. my country has good geological conditions and huge storage potential for storing carbon dioxide. Actively exploring carbon dioxide geological storage technology is of great significance for reducing carbon dioxide emissions. [0003] At the same time, domestic and foreign studies have shown that carbon dioxide is a very efficient oil displacemen...

AI Technical Summary

Problems solved by technology

Carbon dioxide corrosion experiments are usually carried out in high-temperature and high-pressure reactors, without the need for core holders. After the reaction, the cores are taken out and tested in special equipment, so as to obtain the horizontal and vertical values ​​of the cores under different periods of corrosion. Because the horizontal and vertical permeability of the core corresponding to each time point needs repeated experiments, because the position of the core changes after it is taken out, it cannot be reused, and it takes a lot of core and time
