Abstract

The embodiment of the present invention provides a marine controllable source time frequency electromagnetic data acquisition system and method. The system comprises a dipole current source and a cable. The dipole current source is used for generating controllable source time frequency electric field data and controllable source time frequency magnetic field data in a sea area to be detected. The cable is provided with multiple electric field sensors with electrodes, two adjacent electric field sensors on a same cable are used for collecting controllable source time frequency electric field data along a cable direction. A three-component electric field sensor and a three-component attitude sensor are arranged between two adjacent electric field sensors and are used for collecting the controllable source time frequency magnetic field data and attitude data. The cable is provided with a power generation layer for providing power supply. According to the system, since the power generation layer is used to supply power to electronic devices on the cable, the interference brought by using a large-power power supply is avoided, and the technical problems of inconvenient power supply and low accuracy of collected sea controllable source time frequency electromagnetic data of an existing method are solved.

Description

technical field [0001] The present application relates to the technical field of geophysical exploration, in particular to a marine controllable source time-frequency electromagnetic data acquisition system and method. Background technique [0002] In the process of geophysical exploration, especially when conducting geological exploration research on seabed strata, it is often necessary to collect marine controllable source time-frequency electromagnetic data in the sea area to be measured and reflected from the medium below the seabed. Then, according to the collected marine controllable source time-frequency electromagnetic data, the geological structure of the seabed and the electrical characteristics of the reservoir can be analyzed and studied, so as to prepare for the subsequent exploration and development of seabed mineral resources. [0003] The existing ocean controllable source time-frequency electromagnetic data acquisition methods can generally be divided into t...
