Abstract

The invention relates to the field of oil detection, in particular to a seabed node which comprises a shell which is of a hollow structure with an opening in at least one end. The support frame is inserted into the shell through the opening; the end cover is arranged at the opening in a sealing and covering manner; the detection device is arranged on the supporting frame; the signal receiver is arranged on the end cover in a sealing and penetrating mode, the part, located in the shell, of the signal receiver is electrically connected with the detection device, and the signal receiver is used for receiving signals in water. By means of the mode, the problems that the seabed joint structure is complex, the workload in the production and machining process is large, the working procedure is tedious, and the assembling difficulty is large are solved.

Description

technical field [0001] The invention belongs to the field of petroleum exploration, and in particular relates to a seabed node. Background technique [0002] An Ocean Bottom Node (OBN) is a multi-component seismograph located on the ocean floor and can independently collect and record seismic signals. The subsea nodes are deployed on the seabed by the retractable node ship, and the subsea nodes are powered by their own batteries. After all the subsea nodes are deployed, the source ship performs the source excitation task. The seabed node of the seabed and download the data in the seabed node for processing and analysis. The existing subsea nodes have complex structures, cumbersome manufacturing processes, and difficult assembly of components. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention provides a subsea node, which solves the problems of complex structure of the subsea node, cumbersome manufacturing process and difficult ...
