Abstract
The invention relates to a marine seismic source which emits an FM signal linearly increasing from 10 Hz to about 100 Hz. The source has a number of transducers which are flexible sleeves containing a pulsing hydraulic fluid.
Claims14
A marine seismic source comprising:
- a plurality of flexible elongated sleeve-shaped transducers adapted to generate acoustic seismic signals upon application of a pulsing fluid to the interior of the sleeve, each having a first end and a second end and containing a feed pipe which is inside and approximately concentric to said sleeve-shaped walls and extending from the first end to the vicinity of the second end wherein the lead pipe releases said pulsing fluid and is in communication at the first end to said source of pulsing fluid,
- an outlet in said transducers' first end in communication with the space between the sleeve-shaped wall and the feed pipe allowing said pulsing liquid to leave said transducers,
- a source of pulsing fluid,
- a plurality of stiff-walled conduits connecting the plurality of transducers to the source of pulsing liquid and each adapted to be of equal hydraulic length between said source and said transducers,
- whereby said flexible transducers can oscillate and produce a seismic signal.
2 more elements
The apparatus of 1, 3 or 4 wherein the pulsing liquid is seawater.
A marine seismic source comprising:
- at least one transducer having flexible sleeve-shaped walls and adapted to generate acoustic marine signals upon application of a pulsing fluid to the interior of said transducer, and also having a first end and a second end and containing a feed pipe which is inside and approximately concentric to said flexible sleeve-shaped walls and which feed pipe extends from said first end to the vicinity of said second end and is in communication at the first end with a source of pulsing fluid and said at least one transducer having an outlet in the first end in communication with the space between said sleeve-shape walls and the feed pipe whereby pulsing fluid can exit said at least one transducer, and
- a source of pulsing fluid,
- means for modulating the pressure of the pulsing fluid at a frequency in the range of 10 Hz to 100 Hz,
- whereby said at least one transducer is capable of generating a marine seismic signal.
