| 摘要 |
The present invention relates to a pressure tolerant seismic source (1) for deep water survey comprising:
an electromagnetic coil (2) for generating an electromagnetic pulse,
a piston plate (4) movable by said electromagnetic pulse, and
a housing (6) with a first chamber (8) and a second chamber (10) separated by each other via a common bulkhead arrangement (12), wherein
the coil (2) is arranged within the first chamber (8) and the piston plate (4) arranged within the second chamber (10),
wherein the second chamber (10) is at least partly filled with a liquid (14) coupled to the plate (4) so that due to movement of the plate (4) at least one pressure pulse is generated traveling through the liquid (14) within said second chamber (10). |
