Abstract

The invention discloses a porous medium seepage visualization device capable of measuring piezoelectric conversion characteristics. The porous medium seepage visualization device comprises a box body,a liquid inlet pipe, a liquid outlet pipe, a first isolation device, a second isolation device, a first pressure sensor, a second pressure sensor, a seepage pipe, a first measuring electrode, a second measuring electrode, a liquid inlet piston, a liquid outlet piston and a controller. The seepage pipe is arranged in the box body, and the liquid inlet pipe and the liquid outlet pipe are communicated with the seepage pipe; the first isolation device and the second isolation device are arranged in the seepage pipe; the first measuring electrode, the first pressure sensor, the second pressure sensor and the second measuring electrode are connected with the controller; the seepage pipe is made of a transparent material; a transparent window is arranged on the box body; or the box body is madeof a transparent material. When the porous medium is subjected to a seepage experiment, visual observation can be carried out, and the potential difference is visually observed and measured so that the research on the porous medium is deeper and the utilization of the porous medium is more facilitated.

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...
