High-fidelity sampling system for layered deep subsurface fluids


Published Time:

2025-04-23


Product Introduction
The deep underground fluid stratified true sampling system is mainly applicable to the environmental and safety monitoring of various deep underground engineering projects, such as CO2 geological storage, landfill, underground mining, nuclear waste disposal, and groundwater monitoring projects, for stratified sampling of gas and water in deep strata and long-term monitoring of temperature and pressure. The sampling system adopts a multi-layer UI-type structure to achieve independent stratified sampling of gas and liquid in multiple strata, especially suitable for gas-liquid two-phase sampling and real-time temperature and pressure monitoring in ultra-low permeability strata, with minimal disturbance to the strata during the sampling process.
