METHOD AND SYSTEM FOR LOW-FREQUENCY PRESSURIZED SOURCE

摘要

A source element (400) for generating seismic waves includes a housing (401); a partitioning element (407) placed inside the housing (401) and configured to split the housing (401) in a closed chamber (409) and an opened chamber (411); and a valve (403) in fluid communication with the closed chamber (409) and configured to supply high-pressure air to the closed chamber (409) to make the partitioning element (407) oscillates. An oscillation of the partitioning element (407) generates low-frequency seismic waves.
