Abstract

The present invention provides a soil layer response monitoring system which comprises a tubular mounting frame which is provided with a receiving cavity at a tube wall and a deformation measurement module which is connected to one end of the mounting frame to measure the deformation amount of a soil layer at a current position. The mounting frame is equipped with a temperature sensor which is installed in the receiving cavity and is used for measuring the temperature of the current position, a pressure sensor which is installed in the receiving cavity and is used for measuring the pressure of the current position, a concentration monitoring module which is installed in the receiving cavity and is used for detecting the concentration of the current position, and a signal transmitting unit which is used for transmitting each measurement signal to a control center. According to the system, the information of soil layer pore fluid pressure, temperature, sound waves, pore methane gas concentration, deformation response and the like in the exploration process of a natural gas hydrate under a seabed can be monitored in real time, a data support value can be provided for the aspects of making a natural gas hydrate exploration scheme, evaluating an environmental effect and the like, and a reference can be provided for the research and development of a related sea bottom measurement system.

Description

Technical field [0001] The invention relates to the field of underground resource exploitation, in particular to an integrated monitoring system for monitoring soil layer response changes during natural gas hydrate exploitation Background technique [0002] The exploitation of marine gas hydrate has potential geological hazard threats and environmental effects. At present, in the process of international gas hydrate experimental exploitation, the importance of on-site soil response monitoring technology has been gradually realized, but there is no complete monitoring method yet. . Therefore, the development of an integrated underground soil response monitoring system to monitor the mechanical response parameters of the soil during natural gas hydrate mining and obtain on-site in-situ data is of great significance for engineering safety evaluation and the formulation of safety assurance measures. Long-term monitoring of deep-sea energy mining and geological disasters has potentia...
