Acoustic generator and associated methods and well systems

摘要

A well system and associated method can include an acoustic generator which can be used to excite a formation with acoustic waves transmitted from the acoustic generator. Another well system and associated method can include an acoustic generator which can transmit acoustic waves into cement surrounding a casing. Another well system and associated method can include an acoustic generator which can be used to transmit acoustic waves into an annulus surrounding a well screen during or after a gravel packing operation. Another well system and associated method can include an acoustic generator which can be connected in a drill string in close proximity to a drill bit, with the acoustic generator transmitting acoustic waves into a formation ahead of the bit.

1. A well system, comprising:
an acoustic generator which transmits acoustic waves into an annulus surrounding a well screen; a vibration isolation device between the acoustic generator and a string on which the acoustic generator is conveyed; and an isolator section to reflect or attenuate acoustic energy associated with the acoustic waves.
