Description

technical field [0001] The invention belongs to the technical field of greenhouse gas emission reduction, and relates to an experimental simulated CO 2 System for geological storage feasibility. Background technique [0002] CO 2 As a greenhouse gas, large-scale emissions can cause severe environmental damage, causing temperatures to rise and sea levels to rise. CO2 is achieved by permanently sequestering carbon dioxide in underground reservoirs 2 One of the important ways to reduce emissions is an effective means to control climate change caused by the burning of fossil fuels. CO 2 The principle of geological storage is to store CO 2 Injected into high porosity sediments through pipelines, due to CO 2 The density of carbon dioxide is greater than the density of pore water in the sedimentary layer, and there are good sealing conditions around the storage formation. Using this characteristic, CO 2 Can be permanently sequestered in sedimentary layers. The advantage of ...

Problems solved by technology

The geological storage places of different carbon dioxide are quite different, and the structural forms are also different, such as rock thickness, lithology, formation dip angle, etc., CO2 2 Quantitative evaluation of storage and dissipation in the stratum needs to be further studied, lack of experimental instruments for visual observation and quantitative evaluation
