| 发明名称 | Method and system for low-frequency pressurized source | ||
| 摘要 | A source element for generating seismic waves includes a housing; a partitioning element placed inside the housing and configured to split the housing in a closed chamber and an opened chamber; and a valve in fluid communication with the closed chamber and configured to supply high-pressure air to the closed chamber to make the partitioning element oscillates. An oscillation of the partitioning element generates low-frequency seismic waves. | ||

| 主权项 | 1. A source element comprising: a housing; a partitioning element placed inside the housing and configured to split the housing in a closed chamber and an opened chamber; a valve located inside the housing and in fluid communication with the closed chamber and configured to supply high-pressure air to the closed chamber to make the partitioning element oscillates; and a controller located inside the housing and configured to control the valve to fluidly connect (1) a high-pressure source to the closed chamber and (2) a low-pressure source to the closed chamber, wherein an oscillation of the partitioning element generates low-frequency seismic waves. | ||
