Embodiment 1
[0041] A method for in-situ and deep supercritical storage of power plant flue gas, such as figure 1 , 2 , 3 and 6, the specific steps are as follows:
[0042] 1) Under the condition that the normal power generation of the power plant and the safety and stability of the power facilities are not affected, deep drilling is carried out in a certain range of open space in the power plant area 1. The drilling depth exceeds 2000m, and the target well depth reaches 5000m-7000m. Casing 12 is installed in the hole and cemented.
[0043] 2) Sampling the cores of different formations over 2000m in the drilling, and experimentally measure the porosity, permeability, water content, gas adsorption / desorption rate and mechanical strength parameters of rocks in different formations, and combine the relevant geological and hydrological conditions with the formation. Conditions (thickness, dip, water content, and fault characteristics), through comprehensive evaluation, analysis and screening...
