The Research and Experiments of Sea-floor Transient Electromagnetic Method on the Sea

To apply the controlled source time-domain electromagnetic method in the sea-floor exploration, transmitting and receiver sensors should be confirmed before the system is sealed. This paper analogy the configurations in the experiments in the sea floor, choose the central loop and the magnetic dipole-dipole to accomplish the sea-floor detection. The send frequency scope of transmitting system is calculated in order to realize the dragging detection .The dynamic display software that can display the profile map and transmit parameters of the transmitting and received system in real time is designed. The canal of oil in the sea floor is detected by rule and line in this way
