The coal and rock permeability analyzer is used to determine the permeability coefficient of coal and rock specimens that do not disintegrate when exposed to water under indoor conditions. The magnitude of permeability coefficient is determined according to Darcy's law.
The rock permeability coefficient analyzer mainly consists of four key functional parts designed for precise measurement:
Includes the permeability controller, the permeability pressure pump, the vacuum pump, and the permeability pressure chamber.
Achieves the set pressure range of the test in a short time and remains stable within the range control.
Displays the current test pressure and logs the total working time from the beginning to the end of the test run.
Engineered to adapt to various testing environments while maintaining high accuracy and system integrity.
The rock gas permeability tester (gas flowmeter and gas cylinder optional) is a specialized measuring instrument used in the petroleum industry. It is widely used in the analysis and detection of rock gas permeability in oil and gas field exploration and development research and production. Its detection data provides vital, basic parameters for the analysis, research, and evaluation of the physical properties of oil and gas reservoirs.
The pressure regulating bolt of the osmotic pressure pump has been debugged at the factory. The handwheel switch can rotate the handwheel according to the test pressure. Distilled water must be installed inside the osmotic pressure pump. If it is not used for a long time, it must be discharged through the water tank drain valve.
