Improved T_(2cutoff) Value Determination with Core NMR and Conventional Irreducible Water Measurements.

Zhou Cancan, Cheng Xiang Zhi, et al  
It is found that error between T 2cutoff value from traditional NMR laboratory measurements and the estimated theory T 2cutoff value is larger on the basis of analysing 19 cores NMR data. Causes for the above error is analysed, and further, a new core centrifugal method is proposed to calculate T 2cutoff values. Practice application proves the method is feasible.
