Abstract
An isolator for an acoustic logging system includes an outer housing surface, a bore, an outer bore surface, and a first isolator feature positioned between the outer housing surface and the outer bore surface to reduce a collar wave transmitted by the acoustic source.
Claims20
An acoustic logging tool for a wellbore, comprising:
- an acoustic source for generating one or more acoustic waves;
- an acoustic receiver for receiving at least a portion of or a reflection of the one or more acoustic waves;
- and
- an isolator, comprising:
- a housing having an outer housing surface;
- a bore defined within the housing and configured to conduct a drilling fluid through the isolator, the bore having an outer bore surface;
- and
- a first isolator feature positioned between the outer housing surface and the outer bore surface such that the first isolator feature is physically separated from the bore and the outer housing surface, the first isolator feature configured to reduce a collar wave transmitted by the acoustic source.
