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.
