Electronic marine seismic streamer has spread comprising elements of the balancing of the boxes producing

摘要

The streamer is of the type comprising a plurality of rigid electronic boxes 100, of substantially cylindrical shape, distributed along the streamer and dividing the latter into a plurality of substantially cylindrical successive flexible segments 300 linked end-to-end by interposition of the boxes. According to the invention, the boxes are, at least in some cases, linked to each of the two adjacent segments 300, 300' via a spacer element 200, 200' of growing cross-section between a value close to that of the cross-section d3 of the streamer segment, at the linking point with this segment, and a value close to that of the cross-section d1 of the electronic box, at the linking point with this box, the volume of these spacer elements being chosen in such a way that the hydrostatic thrust exerted on the assembly formed by the box and its two associated spacer elements is substantially equal to the weight of this same assembly.
