Description

Technical field [0001] The invention relates to the technical field of porous media research, and in particular to a porous media seepage visualization device capable of measuring piezoelectric conversion characteristics. Background technique [0002] The seepage characteristics of porous media in deep environments play an important role in the exploitation of oil, natural gas, shale gas and other resources. [0003] When the fluid seeps in the porous medium, it will affect the various characteristics of the porous medium. For example, the electric potential of the porous medium during seepage will produce a potential difference. [0004] In the prior art, the generation of the electric potential difference and the influence of the porous medium on the electric potential difference cannot be judged and studied only. Summary of the invention [0005] The object of the present invention is to provide a porous medium seepage visualization device capable of measuring piezoelectric conver...
