Concerted Action of a Radiator and Autonomous Uninhabited Submersibles for Effective Seismic Exploration
Abstract
Introduction: In seismic exploration, they traditionally use stationary geophones attached to a bottom, which is costly and inefficient. Placement of geophones on autonomous uninhabited submersibles allows you to partially automate the seismic exploration, giving up the static scheme of using the geophones for listening to the reflected signals created by a radiator, and switching to a dynamic scheme when a group of autonomous uninhabited submersibles gradually move together with a radiator. In this case, most geophones are busy accepting the reflected signal, and the rest of them are moving together with the submersibles to a new place. This significantly reduces the seismic exploration time. The problem is that the group of the submersibles should act in agreement with the radiator movement. Purpose: We have to develop a method of concerted action for a group of autonomous uninhabited submersibles and a radiator during seismic exploration. Results: A method has been developed to coordinate the movement of a radiator and the progress of a group of autonomous uninhabited submersibles when the radiator, moving along a shifting circular trajectory, constantly describes a circle around the position of the moving group of the submersibles. The values of the optimal parameters of their concerted movement were found on the basis of a specially formulated mathematical model. These values allow you to provide the broadest range of azimuths for the directions of the receipt of the reflected signals emitted by the radiator. Practical relevance: The dynamic scheme of using the geophones leads to an essentially shorter time necessary for seismic exploration in a given area as compared to the static scheme. Besides, the mobility of the entire system formed by a group of the submersibles and a radiator considerably increases, giving you many more ways to rapidly change the parameters of the concerted movement depending on a particular situation during the seismic exploration.Published
