Product Overview

The Liquid Permeability Measurement Device is a reliable and cost-effective system designed to determine the absolute permeability of core samples using liquid under ambient temperature conditions. Based on Darcy’s Law and utilizing the steady-state flow method, this instrument provides accurate permeability readings by analyzing the pressure drop and steady fluid flow rate across a core plug.

Its manual configuration, durable structure, and educational focus make it ideal for universities, research laboratories, and petroleum training centers. The device is especially engineered to facilitate hands-on learning and to enhance understanding of fluid flow through porous media.

Working Principle

The device operates on a straightforward process:
A core plug is placed inside a stainless steel Hassler-type core holder, and a controlled liquid flow is introduced. The system measures both pressure differential and flow rate, which are then used to calculate absolute permeability via Darcy’s Law for single-phase flow in porous media. Data can be manually recorded or processed using pre-designed calculation templates.

Applications

• Academic institutions: Teaching core permeability and flow through porous media

• Research laboratories: Experimental investigations on rock properties

• Technology development centers: Evaluating comparative rock performance

• Oil and gas industry: Supporting reservoir studies and core analysis workflows
