METHOD AND APPARATUS FOR DETERMINING MULTISCALE SIMILARITY BETWEEN NMR MEASUREMENTS AND A REFERENCE WELL LOG |
摘要 |
Pulse sequences are applied to a fluid in an earth formation in a static magnetic field and NMR spin echo signals are obtained. The signals are processed to give a distribution of a relaxation time at a plurality of depths. Semblance between the distributions and a log of a formation property are used to identify depths at which portions of the distributions are similar to the formation property logs. |
