This study examines gas-water distribution in tight sandstone using nuclear magnetic resonance, revealing key insights for accurate reservoir identification.
Key Points
Quantitative analysis found dynamic behavior of methane gas and water in tight sandstone reservoirs.
The study established a two-dimensional NMR gas-water identification model that enhances visualization and characterization.
NMR analysis was conducted under varying pressure and temperature conditions to observe fluid redistribution effects.
Findings suggest effective technical support for reservoir exploration and development, especially in heterogeneous environments.
