Abstract
A tube wave reduction system for a borehole includes a tubular member; one or more openings in the tubular member, the one or more openings having a through-passage and a deformation region surrounding the through-passage; and an absorber in fluid communication with the one or more openings. Also included is a method for reducing an effect of a tube wave.
Claims20
A tube wave reduction system for a borehole comprising:
- a tubular member;
- one or more openings in the tubular member, the one or more openings having a through-passage;
- and
- a deformation region of the tubular adjacent one or more through-passages of the one or more openings.
1 more element
A method for reducing an effect of a tube wave comprising:
- burping at least pressure from a tube wave through one or more openings in a tubular member through which the tube wave propagates by deforming a deformation region adjacent one or more through-passages of the one or more openings;
- and
- absorbing energy from the tube wave thereby reducing a magnitude of the tube wave.
