Processing wait time NMR with double to determine relations T1 / T2, the porosity and the total porosity of the fluid confined.

摘要

Processing of NMR with time of double sphere to determine relations t ~ 1 ~ / T ~ 2 ~, the porosity and the total porosity of the fluid confined.Processes are put the acquisition of NMR data of double time to wait that employs techniques of data with short time of waiting (W ~ s ~) and long time to wait (W ~ 1 ~).The acquired data are processed through the construction and minimisation of a fraction of the maximum probability match so self consistent data in short time and long wait for proIntroduction of an apparent reason t ~ 1 ~ / T ~ 22 and a set of spectral amplitude (~ K ~) independent of the distribution of T ~ 1 ~.This process provides a better accuracy is approximately equal to a factor of double improvement on the conventional process for time easy to wait.
