Embodiment Construction

[0010] The following is attached figure 1 The system connection of the in-situ airtight collection system for sediment pore water of the present invention will be described in detail.

[0011] Several pressure filter type pore water in-situ collection bottles A are connected in series to form a sampling column. Fix it on the bracket E; place the underwater digital acquisition and control subsystem D in the pressure-resistant and sealed barrel C, and fix it on the bracket E; install the sensors B such as the altimeter from the bottom and the position sensor on the bracket E; The electromagnetic coil of the vacuum-preserving ultra-high pressure water valve of the collection bottle, the altimeter from the bottom, the position sensor and other sensor groups B matched with the system are connected to the underwater digital collection control subsystem D in the pressure-resistant barrel C.

[0012] figure 2 It is a structural diagram of filter press type pore water in-situ collec...

Abstract

The invention relates to a system which is used for directly collecting sediment pore water in-situ and recovering the sediment pore water in an air tight mode, belonging to the detection field of matter or articles, with the patent class number G01V. The system comprises a press-filter typed pore water in-situ airtight collecting bottle A, an altimeter used for measuring the height from the bottom, a sensor group B matched with the system such as a position sensor, an underwater pressure-resistant sealing barrel body, a pressure-resistant sealing connector C which is used for underwater connection, an underwater digital collecting control sub-system D, a bracket E which is used for fixing parts and provided with an underwater battery group and a loading counterweight, and a deck display and re-play sub-system F; a sampling pipe assembled by a plurality of sampling bottles vertically passes through the seafloor sediment; and under the control of the sub-system D, the object that the pore water is collected in-situ by layers can be achieved. The system can completely store the chemical property of the pore water compared with the traditional method which collects the sediment on the deck by a sampling device and extracts or squeezes the pore water. The system can be applied to the fields such as investigation, exploitation, underwater environment monitoring, and the like of marine gas hydrate and marine oil-gas, and has wide application prospect.

Description

technical field [0001] The invention relates to an in-situ acquisition technology of sediment pore water for detecting combustible ice (natural gas hydrate), belongs to the field of detection of substances or objects, and has a patent classification number of G01V. Background technique [0002] Natural gas hydrate is a metastable system, and its formation and decomposition are related to the geochemical environment in which it is located. Therefore, various gas and water anomalies closely related to hydrate and their derived geochemical signs can be used for detection . The pore water of shallow seabed sediments retains a large amount of useful seabed geochemical information, so it becomes an important object for detection. At present, at home and abroad, the sediments are first collected on the research ship with a sampler, and then the pore water is extracted or squeezed out on the deck. Use a sampler to collect sediments to the deck. Due to drastic changes in temperatur...
