Well‑logging and permeability testing is a fairly common product in everyday life, yet many people aren’t very familiar with it. Today, we’ll introduce some key information about this technology.

Porosity-permeability joint measurement

Core‑permeability joint measurement is a widely used product with an exceptionally broad range of applications. When operating this instrument, it is important to note that it delivers stable performance and can automatically acquire and process data. Porosity and permeability of core samples can be measured simultaneously or either parameter can be assessed independently. The entire workflow—instrument calibration, testing, data processing, and report generation—is computer‑controlled, enabling full automation. Valve actuation is managed by the computer, while pressure regulation remains manually controlled. In practice, the measurement system comprises a pressure regulator, a pressure vessel, a reference chamber, and a rock sample holder. Pressure sensors and pressure gauges simultaneously monitor both the solid‑phase and pore‑volume measurements of the rock sample, with closed‑loop control implemented via microcomputer. Notably, porosity is determined in accordance with Boyle’s law, and the results are processed and displayed on the computer. The permeability subsystem consists of a pressure regulator, a dry filter, a flow sensor, a pressure sensor, and other components. During the measurement process, the computer automatically tracks and collects pressure and flow data.

The principle underlying the simultaneous measurement of porosity and permeability is based on Darcy’s law, with results processed and displayed by a computer. The testing and data‑acquisition system can collect pressure and flow‑rate readings and, via computer, process data related to permeability and porosity. Pressure sensors in the porosity–permeability tester transmit inlet and equilibrium pressures primarily through four rigid transducers to the monitor and computer. Standard values for process pipelines and setpoints are measured on the control panel. Moreover, the collected data can be further processed by the computer to determine the core’s skeletal volume and pore volume, with reports automatically generated and printed. This product provides research institutions in the petroleum, geological, coal‑mining, and related industries with a reliable basis for analyzing core permeability and porosity. Featuring stable performance, automated data acquisition and processing, simple operation, and rapid measurement, the device employs primarily the transient pressure‑pulse decay method, delivering high accuracy in both pressure and flow‑rate measurements; the flow‑rate calculations derived from pressure‑pulse decay are particularly precise.
