In the realm of reservoir engineering and geotechnical laboratory testing, the Liquid Steady-state Permeameter stands as a cornerstone instrument. Its primary function is to measure the absolute permeability of core samples to liquids, typically following Darcy's Law. By maintaining a constant flow rate and measuring the resulting pressure drop across a plug sample, researchers can derive critical data regarding the flow characteristics of porous media.
Modern permeameters have evolved from simple manual setups to sophisticated, automated systems integrated with AI-driven data acquisition. These systems are vital for calculating reservoir productivity, evaluating the impact of drilling fluids, and optimizing secondary recovery processes in the petroleum industry.
Utilizes steady-state flow conditions where the pressure gradient and flow rate are constant over time. This reduces the mathematical complexity compared to unsteady-state methods and provides highly repeatable results.
Designed to simulate downhole conditions, featuring overburden pressure cells that can handle thousands of PSI, ensuring the laboratory data reflects real-world geological environments.
Equipped with high-precision pressure transducers and flow meters that feed directly into proprietary software for real-time permeability calculation and reporting.
Xi'an, as a historic and technological center in China, has emerged as a global leader in civil engineering and geotechnical instrumentation. The synergy between academic research and industrial manufacturing provides unique advantages for global buyers:
Our R&D team is founded by personnel from Chang'an University and Xi'an Petroleum University, integrating the latest theoretical breakthroughs into commercial hardware.
From CNC machining centers to advanced argon arc welding, our 7500sqm facility controls the entire production cycle, ensuring rigorous quality control and faster lead times.
We provide OEM and ODM services that allow international labs to customize permeameters for specific fluid types or pressure ranges at a fraction of the cost of Western competitors.
With more than 15 years of civil engineering background, Zealchon is located in the new technology industry development zone in Xi'an. We manufacture and supply testing instruments for civil engineering, geological survey, water conservancy, and hydropower. We specialize in:
Our "Xiya" trademark is a recognized leader in the Shaanxi Province, filling critical gaps in the domestic and international instrument markets.
The industry is moving toward "Smart Laboratories." Modern Liquid Steady-state Permeameters are no longer standalone units; they are nodes in a digital ecosystem. Trends include Remote Monitoring, where engineers can oversee core flooding experiments from anywhere in the world, and Predictive Maintenance based on sensor feedback.
International enterprises are seeking more than just equipment; they need comprehensive Lifecycle Support. This includes ASTM/ISO calibration certification, multi-language software interfaces, and robust logistics handling for sensitive electronic components.
Steady-state measures permeability by maintaining a constant flow and pressure drop, ideal for absolute permeability. Unsteady-state uses pressure decay or transient flow, often used for low-permeability samples or gas measurements.
Our systems are compatible with refined oils, brines, distilled water, and certain chemical tracers. We use corrosion-resistant alloys for all wetted parts to ensure longevity.
We use high-precision transducers with a 0.1% FS accuracy and provide a calibration certificate with every unit. Our software includes noise-filtering algorithms to ensure clean data signals.
Yes, we offer customized heat jackets and internal heaters that can maintain sample temperatures up to 150°C, simulating deep reservoir conditions.
We provide comprehensive video training, remote commissioning, and, for large-scale installations, on-site technical support through our global partner network.
Please contact our sales team with your specific core dimensions, required pressure ratings, and fluid types. We provide formal quotes within 24-48 hours.
