METHOD TO DETERMINE SELF-CALIBRATED CIRCUMFERENTIAL CASED BOND IMPEDANCE |
| 摘要 |
<p>A method and device are disclosed for determining the impedance of the cement bond between a borehole casing (140) and its wellbore (110). The invention uses a predicted resonance response as a baseline for determining from the observed resonance response the approximate impedance of the cement. Corrections are made to account for various defects in the casing normalizing the received resonance response.</p> |
