A seabed-based multi-point in-situ long-term observation system

Abstract

The present invention relates to a long-term seabed-based multi-point in-situ observation system which comprises a platform frame, a buoyant material, an underwater acoustic communication device, a beacon, a monitoring chamber, a control chamber, a release control chamber, a central revolving table, ballasting weights and a microelectrode probing system; the platform frame has a cylindrical main body with a total of four layers from the top down; the buoyant material, the underwater acoustic communication device and the beacon are installed on the first layer; the monitoring chamber, the control chamber and the release control chamber are installed on the second layer; the central revolving table is installed on the third layer; and the ballasting weights are installed on the fourth layer. The present invention effectively realizes accurate multi-point locating function, then obtain the data of multiple detecting points in a detected zone upon demands, and finally can analyze and obtain the space distribution information of an active diffusion field. Therefore, important data supports are given to the evaluation on the oceanic environment effects in the process of petroleum leak and hydrate decomposition, thus providing support and services for the implementation of major projects such as seabed petroleum exploitation, and trial exploitation of the natural gas hydrates.

Description

technical field [0001] The invention relates to a seabed-based multi-point in-situ long-term observation system, which belongs to the technical field of ocean observation. Background technique [0002] Marine resources are an important part of national marine rights and interests, and competition for resources such as deep-sea oil and gas hydrate has become the focus of international energy. During the exploitation of seabed natural gas hydrate, due to factors such as temperature, pressure, and external disturbances, the hydrate spontaneously decomposes, producing such as CH 4 、H 2 、H 2 S, O 2 And other by-products, which may seriously affect the stability of seabed, marine engineering infrastructure, marine and atmospheric environment. Therefore, effective and comprehensive long-term monitoring of the natural gas hydrate exploitation process plays an important role in promoting the exploration and exploitation of hydrate resources and the investigation and evaluation of...
