T1-T2 & D-T2 二维谱：区分岩石中不同含氢组分

The T1-T2 two-dimensional spectrum utilizes T1/T2 information combined with T2 relaxation time to differentiate various hydrogen-containing components, such as water, oil, gas, kerogen, asphalt, etc. The D-T2 two-dimensional spectrum distinguishes oil, water, and gas components based on their different diffusion coefficients, reflecting the influence of internal gradient fields, restricted diffusion, and wettability factors within the rock core.
