A Static Exploration Composite Geochemical Microelectrode Probe System

Abstract

The present invention relates to a static cone penetration combined type geochemical microelectrode probe system, comprising a base and a static cone penetration test probe and at least one microelectrode that are disposed on the base; the static cone penetration test probe is disposed in the center of the base; at least one microelectrode is arranged around the static cone penetration test probe; and the conical tip of the static cone penetration test probe is 4-8cm greater than the conical tip length of the microelectrode. The static cone penetration test probe and the microelectrode are combined, and the threshold value of the static cone penetration test probe is set according to the limiting breaking strength of the microelectrode, thereby ensuring that the microelectrode stops penetrating the deposits before reaching the limiting breaking strength, and protecting the microelectrode from being damaged. At the same time, the microelectrode is driven to go deeper. The microelectrode probe system can be applied to a long-term seabed-based multi-point in-situ observation system, can effectively realize the accurate multi-point positioning function, and then finally analyze and obtain the space distribution information of an active diffusion field according to the data acquired at a plurality of exploration points in the exploration region.

Description

technical field [0001] The invention relates to a static detection composite geochemical microelectrode probe 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 many other by-products, which may cause serious impact on seabed stability, 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 eva...

Problems solved by technology

However, the vast majority of microelectrode probes are used to detect the chemical index content of seawater or loose sediments. Even the gel resin probe with the highest structural strength can only detect seabed sediments with relatively low physical and mechanical strength. limited detection

[0006] Obviously, if the microelectrode probe group is directly used to detect various chemical indicators during the process of penetrating the sediment, it is very easy to cause destructive damage to the microelectrode probe, resulting in the failure of long-term observation
