Deep sea transient electromagnetic method detection receiving device and control method thereof

Abstract

The invention discloses a deep sea transient electromagnetic method detection receiving device and a control method thereof. The detection receiving device comprises a controller, a transmitting coiland a receiving coil, and the transmitting coil and the receiving coil are respectively connected with the controller; the receiving coil comprises a first receiving area and a second receiving area,the plane where the transmitting coil is located serves as a reference plane, the orthographic projection of the first receiving area on the reference plane is located in the transmitting coil, and the orthographic projection of the second receiving area on the reference plane is located outside the transmitting coil; and when the transmitting coil generates a primary field, the magnetic flux passing through the first receiving area is equal to the magnetic flux passing through the second receiving area. The electromagnetic detection device is used for solving the problems that in the prior art, mutual inductance is too large and surface data cannot be received due to too large detection energy of an electromagnetic detection device, and in order to reduce the mutual inductance influence of the detection device, deep data in the deep sea environment cannot be received.

Description

technical field [0001] The invention belongs to the technical field of marine detection equipment, and in particular relates to a deep-sea transient electromagnetic detection receiving device and a control method thereof. Background technique [0002] Deep-sea hydrothermal polymetallic sulfide minerals are resources rich in metal elements such as Cu, Pb, Zn, Au, Ag, etc. They usually occur on the seabed at a water depth of 1200-3700 meters, and are widely distributed in mid-ocean ridges and island arcs and back-arc basins and other geological environments. This kind of ore body is accumulated within a few hundred meters, rich and shallow, which is convenient for seabed mining, and the prospect of resource development is very attractive. [0003] At present, in the exploration of seabed oil and gas layers, the marine controlled source electromagnetic method is mainly used. For example, Imamura et al. used the method of vertical galvanic source and horizontal galvanic source ...

AI Technical Summary

Problems solved by technology

[0006] The technical problem solved by the present invention is to provide a deep-sea transient electromagnetic method detection and receiving device and its control method to solve the problem that the electromagnetic detection device in the prior art has too large mutual inductance due to excessive detection energy, and the surface data cannot be received; And in order to reduce the mutual inductance effect of the detection device, the detection energy is small, and the deep data in the deep sea environment cannot be received.
