Description
Technical field
The utility model belongs to technical field of geophysical exploration, is related to a kind of ocean measuring instrument system.
Background technique
Marine seismic prospectiong is the method for carrying out seismic prospecting on ocean using exploration ship.The original of marine seismic prospectiong
The instrument manage, used, and the method for processing data are all essentially identical with land seismic prospecting.Due to being found in continental shelf area
A large amount of oil and natural gas, therefore, marine seismic prospectiong have extremely wide prospect.Marine seismic prospectiong be in the seawater into
The investigation method of row artificial earthquake has the characteristics that 4: 1. most to use non-explosive source；2. being excited in water, received in water, water
Listen device on towing cable (floating cable, cable, streamer) after ship；3. walking the continuous record of boat；4. data is by computer disposal, work
It is high-efficient.Due to These characteristics, make marine seismic prospectiong that there is the production efficiency more much higher than land seismic prospecting, with greater need for
Digital computer handles data.Some special interference waves are commonly encountered in marine seismic prospectiong, such as singing and reverberation,
And bottom related with seabed wave interference.
Submarine seismic exploration technology is one kind of offshore seismic exploration technology, is equally made of focus and acquisition instrument.Sea
Bottom seismic exploration technique mostly uses non-explosive source (based on air cannon), and focus is swum in close to sea, by offshore earthquake
Exploration ship towing；Acquisition instrument is put into seabed to receive the longitudinal and shear wave signal that focus is issued, reflected by seabed bottom.Due to sea
Water cannot propagate shear wave, and wave detector, which is only put into seabed just, can receive shear wave and converted wave.Its main feature is that excite in water,
It receives, excites in water, condition of acceptance is uniform；The continuous observation that can not be brought to.The initially use piezoelectric seismometer of wave detector, it is existing
Developing to piezoelectricity and the use of vibration velocity detector array.Submarine seismic exploration technology can be divided into submarine cable exploration engineering again
(Ocean Bottom Cable, abbreviation OBC) and subsea node seismic detector exploration engineering (Ocean Bottom Node, referred to as
OBN).OBC technology is that hundreds and thousands of a wave detectors are connected on submarine cable, by dedicated spread laying boat position indicator guidance
For the lower cable sinking that will acquire to seabed (submarine cable can be one or more), one end of submarine cable is connected to fixed instrument
On device ship (instrument ship will throw front and back anchor at sea to guarantee that hull does not turn to and not deviate with accommodation), and by marine seismic prospectiong ship
Ocean bottom seismic data is acquired in such a way that design survey line is blown out in sea surrounding.
Subsea node seismic detector exploration engineering (OBN) be node seismic instrument is placed underwater untethered power supply and without
Communication, each node seismic instrument autonomous operation are totally independent of all other node, can be with continuous acquisition data several moons.
The data collection task of OBN is that two ship operations-energy source boat and node seismic instrument lay and recycle ship.Node seismic instrument
Laying mode and spacing do not have restrict, are suitble to full azimuth exploration.When laying node seismic instrument, on each node instrument
It may add along rope yarn or wire hawser, can easily recycle node seismic instrument, similar fisherman recycles long tandem crab pot.It is past thousands of
When node seismic instrument is laid in the seabed of meter Shui Shen, it is not suitable for and adds along rope yarn or wire hawser, node earthquake is generally carried by ROV
Instrument lays instrument according to the measuring point coordinate of design in seabed, when recycling, and goes to recycle deep water one by one to seabed by ROV dive
Node seismic instrument.
Utility application 201710224316.2 discloses a kind of combined type sea bottom earthquake-capturing node (GOBS),
It is submarine earthquake acquisition node made of dragline type metal shell, and external structure includes compressive cabin, upper lower flange, tether
Wirerope.The cabin of combined type sea bottom earthquake-capturing node uses titanium alloy casing, and packaged type uses end face O-ring sealing side
Formula, inside are adopted equipped with digital acquisition device, full-shape wave detector, network communication module, GPS, electronic compass and integrated drive generator, sensor
Spectrum spreading circuit is installed additional with full-shape wave detector to design.
