Abstract
A hydrophone includes a body formed of a flexible, plastic material. The body includes a plurality of channels and each channel may have one or more wells. The wells are adapted to receive an active element which includes mounting hardware. The mounting hardware includes a soft, rubber grommet or other means which suspends the active element, thereby permitting the flexing of the body without introducing that motion to the active element.
Claims23
A seismic sensor comprising;
- an axially oriented, flexible plastic body including a plurality of axially oriented channels defining at least one well therein;
- at least one active element supported by the body on a mounting plate having opposing ends, the active element sensitive to a seismic signal, the at least one active element retained within the at least one well;
- a grommet on each of the opposing ends of the mounting plate, and
- a mounting bracket adjacent each end of the mounting plate and grasping the grommet on each end of the plate.
A seismic streamer cable having a plurality of seismic sensors positioned therealong at intervals, each of the plurality of seismic sensors comprising a flexible body retaining at least one active element sensitive to a seismic signal, the body including a plurality of axially oriented channels defining at least one well in each of the plurality of channels, the at least one active element retained within the at least one well in its respective channel;
- each of the seismic sensors supported by a respective mounting plate having opposing ends;
- and
- means for isolating strain from the streamer cable to each of the sensors including a grommet on each of the opposing ends of the respective mounting plate and a mounting bracket adjacent each end of the mounting plate and grasping the grommet on each end of the plate.
A seismic sensor on a seismic streamer cable, the seismic sensor comprising
- an axially oriented, flexible plastic body including a plurality of axially oriented channels defining at least one well in each of the plurality of channels;
- at least one active element supported by the body in the at least one well in each of the plurality of channels and sensitive to a seismic signal;
- and
- means for isolating strain from the streamer cable to the active element:
- wherein each of the active elements is supported by a respective mounting plate having opposing ends;
- and
- means for isolating strain from the streamer cable to each of the active elements including a grommet on each of the opposing ends of the respective mounting plate and a mounting bracket adjacent each end of the mounting plate and grasping the grommet on each end of the plate.
