Description
Technical field [0001] The patent of this invention relates to high temperature and high pressure price adjustment, supercritical CO 2 The pressure measurement along the foam steady-state seepage process is a method for flexibly measuring the pressure along the process of the supercritical CO2 foam seepage process under the high temperature and high pressure conditions of high temperature and high pressure, and belongs to the field of foam low permeability. Background technique [0002] In the process of geological experiments, CO under high temperature and high pressure conditions 2 The pressure parameter along the steady-state seepage of foam is a very important technical issue. Since the geological conditions are high-temperature and high-pressure conditions, it is difficult to obtain the pressure parameters along the seepage process by direct measurement methods using existing technologies. Therefore, an accurate and effective measurement method is used to obtain the st...
