Porous medium permeability testing device

Abstract

The invention discloses a porous medium permeability testing device, which is composed of a first gas source module, a reactor module, a backflow module, a vacuum-pumping module, a gas-liquid separation module and a mesh plate template. With the arrangement of a device capable of rapidly guaranteeing vertical installation of reactors and by the mode of arranging multiple reactors, the problem that existing devices cannot be applied in reaches on permeability of porous mediums is solved. By the use of the device, laboratory testing researches on permeability rules of a porous medium can be realized.

Description

technical field

[0001] The invention relates to the technical field of experimental test devices, in particular to a test device for the penetration law of porous media. Background technique

[0002] Porous media, such as sandstone, soil, and accumulations of artificial granular materials, are generally a common space occupied by multiphase substances, and it is also a combination of multiphase substances. The part of the space without a solid skeleton is called pores. Liquid or gas or gas-liquid two phases are shared, relative to one of the phases, other phases are dispersed in it, and the solid phase is the solid skeleton, and some cavities that constitute the void space are connected with each other. Its main properties include porosity, wettability, permeability, and capillary pressure. Among them, permeability is an important basic data of seepage mechanics and related engineering technology, which often needs to be studied in the laboratory. The use of supercritical ...
