Description
Technical field
The invention belongs to applied geophysics exploitation method, it is related to marine seismic prospectiong, marine natural Electromagnetic Sources and can
Control source electromagnetic survey technology, more particularly to a kind of small intelligent offshore earthquake electromagnetic data acquisition system.
Background technology
Current marine electromagnetic data acquisition mode mainly has following three kinds：
First, independent acquisition station is sunk to the bottom, excitaton source drags, such as EMGS, OHM, Schlumberger generally use in the world
Sea-floor electromagnetic acquisition station and it is high-power drag field source, laid acquisition station in advance, excitation then dragged above acquisition station, can
To complete ocean controllable source electromagnetism and magnetotelluric data acquisition simultaneously.
Second is that acquisition cable is synchronously dragged with excitation cable, a kind of pull-type ocean controllable source electric field number released such as PGS companies
According to acquisition system.The system only gathers an electric field component along cable direction, does not gather any magnetic-field component data.But
The marine electromagnetic field data for not measuring any magnetic-field component is incomplete, is unfavorable for the electricity to seabottom geology structure and reservoir
Property feature carry out detailed understanding and analysis.In addition, it is along the electrode of cable directional spreding nor equally distributed, close to adopting
The electrode density collected on the cable near ship is larger, and is just distributed away from the electrode on the cable at acquisition vessel very dilute
It dredges.In addition, this pull-type ocean controllable source electric field data acquisition system is only capable of carrying out the frequency of time-domain or single frequency point respectively
The electric field data collecting work in rate domain.
Third, cable sinks to the bottom laying, excitaton source drags for marine electromagnetic data acquisition, it is such as open there is presently no actual application
Number disclose a kind of sea-floor electromagnetic cable data acquisition system for the patent application of " CN102472829A ", working method is sea
Bottom electromechanical cable (EM OBC-ElectroMagnetic Ocean Bottom Cable) is first to launch to be routed to sea by cable boat
Then bottom tows underwater controllable electric power from emission source ship and (is sent out away from moving ahead in a certain distance of seabed and powering into seawater
Penetrate controllable electric magnetic wave), the electromechanical cable that seabed is routed to by launching in advance gathers sea-floor electromagnetic data.After data acquisition,
Cable boat recycles sea-floor electromagnetic cable, and dispensing is routed to new measurement work area, the then repeatedly data acquisition of sea-floor electromagnetic signal
Operation.
The patent application of Application No. " CN201310292356.2 " disclose a kind of pull-type ocean controllable source electromagnetism and
System for acquiring seismic data, the system is by being placed in the electric field sensing being uniformly or non-uniformly distributed in three or three or more towing cables
Device (unpolarizable electrode), three-component line of induction ring type or three-component fluxgate type magnetic field sensor and by hydrophone or accelerometer
The sonic sensor composition of composition, to Measuring Oceanic three-component magnetic-field component, along cable direction and vertical cable directional spreding
Ocean electric field component EXAnd EYAnd multicomponent marine seismic data.The present invention can acquisition time domain and frequency domain simultaneously sea
Foreign electromagnetic data can improve to several times once construct marine electromagnetic and the collection capacity of multicomponent marine seismic data, effectively carry
High target acquisition precision is realized and carries out marine minerals and oil gas using ocean controllable source time-frequency electromagnetism and marine seismic prospectiong technology
The joint exploration and overall merit of resource and methane hydrate.
For controllable source electromagnetic method using more, it is all frequency domain or time-domain method to have method.I.e. or a frequency point one
It excites and measures a frequency point, such as controlled source audio-frequency magnetotelluric method (CSAMT) (CSAMT)；Or one pulse (square wave) of excitation measures it
Attenuation curve at any time after power-off, such as long offset transient electromagnetic method (LOTEM).In addition, existing methods measurement parameter only limits
In an electric field, a magnetic-field component, such as CSAMT methods；Or a vertical magnetic field is only surveyed, such as LOTEM methods.Its physical property studied ginseng
Number is single, is only limitted to resistance parameter.Therefore, these methods are solving the ability of geological problem and precision etc. with being actually subjected to
It seeks survival in gap, it is difficult to geological problem existing for satisfactory solution.
Sinking type marine electromagnetic data acquisition system that is all currently in use at present and announcing all is using counterweight cement
Block takes marine electromagnetic data acquisition station to seabed, after data acquisition terminates, from the acoustic control unit on deck to seabed
Electromagnetic data acquisition station send control signal, start electromagnetic data acquisition station acoustics or mechanical trip, make electromagnetism number
It is separated according to acquisition station with counterweight cement block, after by the glass floating ball on electromagnetic data acquisition station top, acquisition station is taken on sea
It is recycled.This sinking type acquisition station volume is big, of high cost, weight weight, largely can not lay highdensity two in seabed
Tie up marine electromagnetic data acquisition survey line or three-dimensional grid.In addition it is free subsidence when acquisition station is launched, does not pinpoint dispensing precision
Control, when recycling are to take marine electromagnetic acquisition station on sea to by glass floating ball, low construction efficiency, also because of acoustics or machinery
Release device failure causes acquisition station that can not be separated with counterweight cement block, causes acquisition station recycling failure and loses.
