翻译T1-T2二维谱利用T1T2信息结合T2驰豫时间可以区分不同含氢组分如水、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、气组分反映岩心内部梯度场、受限扩散以及润湿性等因素的影响。

The T1-T2 two-dimensional spectrum utilizes T1/T2 information and combines with T2 relaxation time to differentiate different hydrogen-containing components, such as water, oil, gas, kerogen, and asphalt. The D-T2 two-dimensional spectrum distinguishes oil, water, and gas components by their different diffusion coefficients, reflecting the influence of the internal gradient field, restricted diffusion, and wetting properties in the rock core.
