Embodiment Construction
[0125] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0126] The present invention realizes multifunctionality, under certain conditions, the permeability of the rock core can be measured, the connection of the device can be changed, and the change of the adsorption amount of the rock core in different states can be measured; it lies in changing different experimental conditions, measuring the adsorption amount of the rock core, thereby establishing different Physical factors, including the water content of the core, temperature, pressure, etc., affect the adsorption capacity.
[0127] The application principle of the present invention will be described in detail below in conj...
