A self-floating seabed temperature detection system

Abstract

The invention discloses a self-floating undersea temperature detecting system which comprises an undersea signal collecting base station and a temperature detecting probe. The temperature detecting probe can be used for multiple times and fully makes contact with seawater, temperature detecting units are arranged in the temperature detecting probe and combined conveniently and flexibly to output digital signals, and the data quality can be effectively improved; through the undersea signal collecting base station, the instrument recycling rate is guaranteed, and the sea temperature detecting risk is reduced. The self-floating undersea temperature detecting system can detect the undersea temperature both in a neritic region and in an abyssal region and is beneficial for long-term undersea temperature detecting due to long sea staying time.

Description

technical field [0001] The invention belongs to the field of geophysical measurement, and in particular relates to a seabed temperature detection system for geophysical measurement. Background technique [0002] Seafloor temperature detection is an important means of geophysical methods, especially the temperature gradient detection results in the heat flow region can directly reflect the heat transfer process inside the earth, helping us to carry out research on geodynamics and the evolution process of the internal heat-driven framework in the earth, providing a basis for the seabed The exploration of oil and gas and other mineral resources provides evaluation basis. [0003] At present, seabed temperature detection is mainly realized by oil drilling temperature measurement and seabed heat flow meter detection. Among them, oil drilling temperature measurement is mainly carried out in oil areas and shallow sea areas, with many operating conditions, high cost and low efficie...

AI Technical Summary

Problems solved by technology

Submarine heat flow meters can easily measure the temperature of the seabed within a kilometer, but as the depth of seawater increases, the difficulty of detection increases exponentially, the efficiency decreases and the risk greatly increases

When the probe of the submarine heat flow meter is inserted into the sediment, it will cause frictional heat generation, and the specific heat stabilization time is not easy to grasp. At the same time, the seabed temperature in some specific sea areas is affected by the interior of the earth and shows drastic changes over time. A submarine heat flow meter is required. Stay in the sea for a long time to obtain accurate temperature information

In addition, during the working process of the submarine heat flow meter, the measurement ship will drift due to the surge, and the position of the submarine heat flow meter on the seabed may change under the action of the steel cable, which may even cause damage to the submarine heat flow meter and cause the operation to fail. A new topic is raised for the application of submarine heat flow meter
