METHOD FOR DETERMINING WETTABILITY OF AN OIL RESERVOIR |
摘要 |
<p>A method for determining wettability of an earth formation zone surrounding a borehole, including the following steps: introducing paramagnetic ions into the water component of the zone; performing NMR measurements on the zone, and determining an NMR relaxation time parameter for the zone; extracting a fluid sample from the zone; performing NMR measurements on the sample, and determining the NMR relaxation time parameter for the sample; and determining wettability of the earth formation zone using the determined relaxation time parameter for the zone and the determined relaxation time parameter for the sample.</p> |
