T1-T2 & D-T2 二维谱：区分样品中不同含氢组分

The T1-T2 2D spectrum utilizes the T1/T2 information and combines it with T2 relaxation time to differentiate between different hydrogen-containing components in the sample, such as water, oil, gas, kerogen, asphalt, etc. The D-T2 2D spectrum distinguishes between oil, water, and gas components by resolving their different diffusion coefficients, while also reflecting the effects of internal gradient field, restricted diffusion, and wettability in the core.
