MARINE STREAMER ELECTRONIC UNIT Russian patent published in 2019 - IPC G01V1/20 G01V1/38 G01V13/00 

FIELD: physics.

SUBSTANCE: invention relates to geophysics and can be used for marine geophysical survey. Disclosed is electronic unit (20), the configuration of which allows use thereof as part of marine streamer and surround it with vein cable of marine streamer, wherein said electronic unit (20) includes at least housing (21), at least partially flexible, at least partially made of a polymer material. Said housing (21) extends along longitudinal axis (X) between two lateral ends (22, 23) and has hollow cylindrical core (25) for enclosing therein a portion of said marine streamer coaxial cable and a plurality of walls (26) projecting outward from said hollow cylindrical core (25), bounding spaces (27), the configuration of which provides for enclosing electronic means therein and having free ends (28). One of walls (26) and hollow cylindrical core (25) of housing (21) have through slot (60), wherein said through slot (60) extends longitudinally throughout the length of housing (21) from one side end (22) to other lateral end (23). Electronic unit also includes electronic board (45), including at least one flexible part (46) and having a configuration providing at least partial support on free ends (28) of at least two of said plurality of walls (26).

EFFECT: technical result is to improve the information content of the received data.
