发明名称 Noise reduction in particle motion sensing seismic streamer
摘要 An apparatus includes particle motion sensors and a streamer that contains the particle motion sensors. The streamer is to be towed in connection with a seismic survey, and the towing of the streamer produces a turbulent flow. The streamer includes an inner cable that contains the particle motion sensors and a fluid containing layer to surround the inner cable to reduce noise otherwise sensed by the particle motion sensors due to the turbulent flow.

主权项 1. A seismic streamer comprising: pressure sensors; particle motion sensors; a solid core inner cable and an outer skin surrounding the solid core inner cable; and a fluid containing layer between the outer skin and the solid core inner cable, wherein at least one of the particle motion sensors is connected with the seismic streamer such that the at least one particle motion sensor is static with respect to the solid core inner cable.
