Some Case Studies of Nuclear Magnetic Resonance in the Petroleum Industry【一】

Case 1: Core Porosity Accuracy Test

Table 1. Core Porosity Accuracy Test

Case 2: Comparison of Pore Structure Distribution (Shale vs. Sandstone)

Figure 1. Comparison of T2 Distributions in Conventional Core and Shale

The T2 relaxation time distributions of shale and sandstone differ significantly. Shale-specific low-field NMR instruments are capable of detecting nanoscale pore signals.

Case 3: Comparison of Shale T2 Distributions under Different TE Values
