Problems solved by technology

In areas where high-impedance rock formations such as evaporites and basalts develop, it is often difficult for conventional reflection seismic to obtain geological information of strata below the high-impedance layer
[0004] The equipment of the detection system is mainly composed of submarine seismic acquisition nodes and other supporting devices. The foreign supporting devices are refitted from the entire ship, and the system is extremely large.
However, there is no molding equipment in China, and the supporting delivery system is even more lacking.

The system comprises a space positioning part, a signal control part, a source power part, an electric winch part, a fixation installation part and an auxiliary platform part. The parts cooperate with each other so as to realize adaptive arrangement of submarine earthquake acquisition nodes. The system is applied to submarine earthquake detection, oil gas exploration and geological investigation and has the advantages of high automation degree and accurate arrangement positions.

Description

technical field [0001] The invention belongs to the field of geophysical measurement, in particular to the field of marine survey, and relates to a self-adaptive control delivery system for seabed seismic acquisition nodes. Background technique [0002] Seabed seismographs have the advantages of low noise, large array length, and higher detection accuracy compared to sea surface seismic streamers, and have become an important means for studying deep ocean geological structures and deepwater oil and gas exploration. [0003] Due to the high drilling costs and high investment risks in the exploration of deep-water oil and gas resources, in order to improve the success rate of drilling, various oil companies must carry out various geophysical surveys within the scope of the well site. Therefore, the density and information of submarine seismometers The volume demand is also far beyond the general seabed structure survey. Therefore, the submarine seismic detection system based ...
