Case 1: Accuracy Test of Core Porosity Case 2: Comparison of Pore Structure Distribution (Shale vs. Sandstone) Case 3: Comparison of Shale T₂ Distribution Maps under Different TE Values

Coalbed methane primarily exists in an adsorbed state within coal pores. A proper understanding of the pore structure and distribution characteristics of coal is a crucial basis for studying coal reservoir porosity, spatial structure, fluid flow characteristics, and the recoverability of coalbed methane.

In tight reservoirs, fluid flow characteristics differ from those in conventional reservoirs and are strongly influenced by the microscopic pore structure. Accurately understanding the reservoir’s pore architecture is crucial for calculating recoverable reserves and formulating effective development plans.

Core analysis is an essential method for understanding the geological characteristics of oil and gas reservoirs. As a porous medium, rock exhibits complex phenomena, including its internal pore structure, the behavior of molecules within the pores, and ongoing reaction processes. The interrelationships among these phenomena constitute a central focus of core analysis research.

Core analysis is an essential method for understanding the geological characteristics of oil and gas reservoirs. As a porous medium, rock’s internal pore structure, the movement of molecules within the pores, reaction processes, and the interrelationships among these phenomena constitute important topics in core analysis research.

At present, nuclear magnetic resonance has become a powerful tool in petroleum exploration. It can accurately analyze core pore structures and provide comprehensive pore-related information, including porosity, pore distribution, permeability, bound fluid saturation, and free fluid saturation.

Newmai’s low-field magnetic resonance equipment offers a wide range of powerful functions in research fields such as petroleum energy, rocks, geotechnical materials, and concrete, specifically targeting porous media materials like cores, cuttings, permafrost, and concrete.
