NMR-DNA-FINGERPRINT |
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 relaxation time at each of the plurality of depths. A quasi-DNA is obtained by autoscaling and a nonlinear mapping of T2 component logs and non-NMR logs. Similarities between the quasi-DNA of the two types of logs are used to estimate formation lithology and fluids. |
