Problems solved by technology

[0003] The quality of rock permeability is generally expressed by the numerical value of permeability. The determination method of rock permeability is based on Darcy's law. Only gas or liquid can be used to measure the permeability of rock, so only one parameter in gas permeability or liquid permeability can be measured, and the existing permeameter cannot adjust the pressure, and cannot complete the permeability of rock under different stress conditions At the same time, it is difficult to ensure the airtightness between the permeameter and the rock, which will easily lead to inaccurate measured permeability values.

Abstract

The invention relates to a rock permeability measuring device, in particular to a geology rock permeability measuring device which comprises a main supporting frame, a fixed cylinder, a supporting slide rail frame, a rotating cylinder, a blocking ring and the like. A fixed cylinder is fixedly installed above the main supporting frame, a supporting sliding rail frame is fixedly installed on the top face of the fixed cylinder, the bottom of the fixed cylinder is rotationally connected with a rotating cylinder, the rotating cylinder is rotationally connected with the main supporting frame, and the bottom of the rotating cylinder is fixedly connected with a blocking ring. Under the influence of the gravity of the weight, the sliding circular frame can move downwards to extrude air in the fixed cylinder and the rotating cylinder, and gas or liquid in the fixed cylinder and the rotating cylinder gradually permeates through the rock sample, so that the equipment can measure the gas permeability and the liquid permeability of the rock sample.

Description

technical field [0001] The invention relates to a rock permeability measuring device, in particular to a rock permeability measuring device used in geology. Background technique [0002] Rock permeability is the ability of fluid to flow in rock under a certain pressure difference. Rock seepage has an important influence on the mechanical properties of rock. It will change the stress of rock and cause rock deformation, cracking, softening, mudification or dissolution. , thus jeopardizing the stability of the rock mass. Permeability is a parameter that characterizes the ability of soil or rock to conduct gas or liquid. In the field of oil and gas exploration, permeability is an important index to measure the ability of the core to allow fluid to pass through. It directly affects the oil quality. , Gas well production. [0003] The quality of rock permeability is generally expressed by the numerical value of permeability. The determination method of rock permeability is based ...
