Towrope type ocean controllable source electromagnetism and earthquake data collection system

Abstract

A towrope type ocean controllable source electromagnetism and earthquake data collection system is composed of electric field sensors (non-polarized electrodes) distributed in three or more towropes uniformly or not, three-component induction coil type or three-component fluxgate type magnetic field sensors and sonic sensors composed of hydrophones or accelerometers and is used for measuring ocean three-component magnetic-field components, electric field components EX distributed in the cable direction, electric field components EY distributed in the vertical cable direction and ocean earthquake data. The towrope type ocean controllable source electromagnetism and earthquake data collection system can collect ocean electromagnetism data and ocean earthquake data in the time domain and the frequency domain at the same time, increase the collection quantity of ocean geophysics data of advancing construction at a time in a multiplying mode, effectively improve the target detection precision and explore and evaluate ocean mineral products, oil and gas resources and methane hydrates through combination and comprehensive application of ocean controllable source time-frequency electromagnetism and the earthquake exploration technology.

AI Technical Summary

Benefits of technology

This patented device has several technical features that make them more efficient than current methods: they have multiple components (electric fields) placed next to each other without affecting their performance or functionality; there are no external devices like an inductor near certain points on these components, making this method highly reliable even with long cables used by different sources). Additionally, the use of magnetometer elements allows for precise measurements over longer distances compared to previous techniques such as wireline survey tools.

Problems solved by technology

Technological Problem: Current Electromagnet Data Collection Method for Seafloor Electro Magnetocean Networks involves acquiring accurate measurements through remoted waterborne vehicles equipped with cables attached to them. However, due to factors like environmental conditions including sea currents and tidality issues, the placement location may change frequently during exploration operations. Additionally, when performing surveys over large areas, the movement of the vessel carrying the equipment causes vibrations and disturbances, making it challenging to accurately gather important data about the environment surrounding the survey zone.
