Distributed optical fiber sound wave transceiver

The invention relates to a distributed optical fiber sound wave transceiver which comprises a shell which is of a hollow columnar structure; the plurality of back liners are arranged in the shell, the plurality of back liners are arranged at intervals along the axial direction of the shell, and the adjacent back liners are connected through photoelectric connectors; the optical fiber is arranged in the shell, the optical fiber is provided with a plurality of receiving sections, and the optical fiber of each receiving section is wound on the backing according to a preset angle; and at least one acoustic signal source. The method has the beneficial effects that the distributed acoustic characteristics in the exploratory well are extracted in a large range and in all directions, and the sensitivity of signal response is improved. 本发明涉及一种分布式光纤声波收发器，包括：外壳，为中空的柱状结构；多个背衬，设置在外壳内，且沿外壳轴向有多个间隔排布的背衬，相邻背衬通过光电连接头连接；光纤，设置在外壳内，光纤设置有若干个接收段，每个接收段的光纤按照预设角度缠绕在背衬上；至少一个声波信号源。本发明的有益效果为：实现了大范围、全方位的对探井中的分布声学特征进行提取，提高了信号响应的灵敏度。
