Method and Apparatus for Acoustic Noise Isolation in a Subterranean Well

摘要

The disclosure provides a well system component configured to reduce excessive acoustic noise that would otherwise interfere with acoustic telemetry systems. Specifically, the well system component includes a body configured to be coupled to a pipe string, at least one lobe extending radially from the body, and a pad disposed on the at least one lobe and extending radially from an outer radial extent of the at least one lobe. The well system component can be installed at critical acoustic transmission locations, such as at the location of a hanger, at or near a flex joint in a wellhead installation, and/or at or near a rig floor or deck of an offshore rig.

主权项

1. A well system component for reducing excessive acoustic noise in downhole acoustic telemetry systems, comprising:
a body configured to be coupled to a pipe string; at least one lobe extending radially from the body; and a pad disposed on the at least one lobe and extending radially from an outer radial extent of the at least one lobe, the pad being configured to reduce acoustic noise generated within a marine riser and/or a wellhead installation.
