翻译T1-T2二维谱利用T1T2 信息结合T2驰豫时间区分样品中不同含氢组分如水 、油、气、干酪根、沥青等。D-T2二维谱则通过扩散系数的不同分辨油、水、气组分同时反映出岩心内部梯度场、受限扩散以及润湿性等因素的影响。

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.
