Description
Technical field
The utility model relates to a kind of seismograph, and particularly relating to a kind of note type does not have the cable seismograph.
Background technology
1, seismic instrument present situation
The high accuracy number seismograph is to be used for the artificial or earthquake signal of record, seek the exploration instrument for geology of oil, gas, coal and other mineral resources then according to the record of these seismic signals, and can be used for surveying earth ' s internal structure, carry out engineering and geological hazards prediction etc.
Method of seismic exploration remains the main means at land and seafari oil and natural gas at present, also be the important method of exploration of other mineral resources simultaneously, and be widely used in studying earth ' s internal structure, engineering exploration and aspects such as detection, geological hazards prediction.Its basic skills is to bury to put thousands of and even up to ten thousand seismic event sensors (being seismoreceiver) on the ground of exploration target area, at sea then be to float cable (floating cable), excite artificial earthquake with explosive or vibroseis (on land) or high-pressure airgun (at sea) then every seismoreceiver of tens of meters parcels with the long sea of the several 1-2km of sea exploration vessel drag and drop.Seismic event is propagated to deep under ground, the interphase that runs into the heterogeneity stratum will produce reflection, seismoreceiver picks up reflection wave and converts thereof into analog electrical signal, by high-precision digital seismograph these analog electrical signals is converted to digital signal record then and gets off.The mass data that ground observation receives is carried out complicated signal Processing and Inversion Calculation by indoor high-speed computer, just can obtain clear reliable underground structure image, finally determines the position and the degree of depth of mineral resources.
Digital seismograph with the mineral resources geophysical survey can be divided three classes according to data transfer mode: wire-link telemetry seismograph, wireless telemetering seismograph, no cable memory-type seismograph.
The seismographic feature of wire-link telemetry is to be sent instruction and transmitted image data by wired system fully.In present open-air practical application, occupy leading position, occupy most shares in seismograph market, the world, 408/428 series that Sercel company is arranged commonly used, System IV, the Scorpion of ION company and Aries II system, the Summit system of German DMT company, Uni Q system of U.S. WesternGeco company etc.Present instrument in China's oil and the use of gas prospecting industry greatly partly is the wire-link telemetry seismograph from external import.
The instrument that utilizes wireless system to send instruction and transmission image data is called the wireless telemetering seismograph, generally is used for surface condition construction down distinguishingly, also occupies certain market.The Wireless Seismic system of the BOX system of Fairfield company and Wireless Seismic company is the wireless telemetering digital seismograph.
Britain Vibtech company (by Sercel corporate buyout, developing into the Unite system) releases a kind of novel telseis instrument system---IT system first, called after " honeycomb earthquake " acquisition system.The wireless system that it is different from the past, IT system adopts the patented technology of cellular radio.Communicating by letter between remote control acquisition component (Remote Acquisition Unit-RAU) and their " local node " (local node) adopted the 2.4GHz ISM band that need not licence.When blowing out, IT system adopts cellular radio to come the remotely monitored sensor data to recording-member, and then by cable line geological data is delivered to central recording unit.
No cable memory-type seismograph is a kind of seismograph of specific type, it is characterized in that: do not have big line, do not have transmission of seismic data; Each acquisition station receives blows out storage automatically after the data, with special data recovery system all is blown out data again and takes out from acquisition station; There is the part instrument to utilize wireless system, but do not receive data, do not monitor the duty of acquisition station the order such as fire of used acquisition station.
No cable formula register system (directly writing down with the paper section in early days) is all adopted in the observation of the earthquake station, in field of seismic exploration, no cable system the earliest is the SGR (Seismic Group Recorder) of the seventies by the development of Amoco company, early stage SRG system is " blind putting (shoot blind) ", be in the surface units of SGR magnetic tape station to be installed, in case after surface units was laid, seismic data recording can't know whether surface units is working properly on tape.Though this method is not accepted by a lot of people, because he can obviously enhance productivity, at noontide, once has 20 field parties to equip this instrument.When " blind putting ", nearly 1% seismic trace had problem at that time, and this also allows in present wired system.
American I N company (former I/O company) released the long-range earthquake signal recorder of RSR (Remote Seismic Recorder) in 1999, can realize the earthquake data acquisition of 6 analog detector passages.The RSR system can with the IMAGE system compatible of ION company, the two can be formed wire and wireless and mix acquisition system.ION company 2002 with the remote logging instrument of RSR system upgrade to VectorSeis SYSTEM IV system, be called VRSR2.VectorSeis SYSTEM IV central control system has control module (being called V2), radio-frequency antenna, central transceiver and central transceiver controller to constitute.V2 by the data acquisition of acquisition instructions startup VRSR2 acquisition station, detects the state of VRSR2 by radio-frequency antenna and all VRSR2 formation radio-frequency (RF) telemetry system.Basic identical with function and the structure of RSR, but no longer support analog detector, but adopted three-component MEMS digital geophone.
No cable memory-type earthquake-capturing station is not owing to have real time monitoring record and on-the-spot quality monitoring means commonly used, so can't generally be accepted by industry member, using in China, existence does not meet problems such as Seismic Operation standard yet, up to the present, also not having cable memory-type earthquake-capturing stands in China and carries out actual seismic exploration.But because the accuracy requirement of seismic prospecting makes that the road number of seismic instrument is more and more, according to expert's estimation both at home and abroad, along with the demand of seismic prospecting precision, oil and gas industry circle needs the instrument of 30000 roads to 50000 roads soon, by 2025, perhaps we needed the earthquake-capturing instrument in 250,000 roads.And for the wired acquisition instrument more than 50000 roads, administering and maintaining of cable is very difficult, also needs to spend a large amount of costs.So it will be the developing direction of next step seismic prospecting instrument that at present a lot of scholarly forecasts do not have cable memory-type earthquake-capturing station.
Because the development of no cable memory-type seismic instrument is relatively easy, has many universities, research institution and company to carry out the development work at this kind earthquake-capturing station both at home and abroad at present.Domestic have the GPS time service seismograph of east geophysics company, the submarine seismograph and the metallic ore of Inst of Geology and Geophysics, Chinese Academy of Sciences to explore the no cable telemetric seismic instrument of no cable memory-type seismograph, Jilin University.There is the FireFly of American I N company not have cable seismic acquisition configuration, the Unite system of French Sercel company, the Ultra of U.S. Ascend Geo company abroad and do not have GSR (the Geospace Seismic Recorder) system of cable land seismic acquisition configuration, U.S. OYO Geospace company, the Z system of U.S. Firfield company, the Sigma system of U.S. Seismic Source company.
At present, all large-scale seismic prospecting instruments of China all depend on from developed country's imports such as the U.S., France.Because no cable memory-type earthquake-capturing station is not also accepted by China's geophysical survey circle, also there is not this seismograph of domestic enterprise procurement at present.Homemade no cable memory-type seismic instrument also is in the development stage, does not also have formal product to come out.
2, the weak point of not having cable memory-type seismic instrument now

2. have or not the seismographic acquisition station of cable memory-type can not send data to the real-time quality control that central station is realized data: this is the difficult problem that up to the present can't solve.Do not have the real-time quality control of data, just can not know the quality of earthquake data acquisition at the scene, comprise whether the power, acquisition station work of excitation energy be normal, wave detector work is whether normal etc.In the construction in the open air, can excite hundreds of big gun record every day at present,, mend big gun again and will spend a large amount of man power and materials if after indoor playback, find that a large amount of malfunction data are arranged.So the construction method of this instrument is not also accepted by seismic prospecting circle of China.
3. it is synchronous that the GPS of acquisition station only is used for time service, most of conventional memory-type does not have that cable earthquake-capturing station does not position or bearing accuracy is not enough: because each acquisition station will carry out synchronous data collection, time service type GPS receiver can provide the output of 1pps time signal, can reach the precision of RMS20nS, be enough to satisfy the synchronization accuracy of instrument requirement.But because GPS single-point bearing accuracy is lower, be generally ± 10m, when having SA to influence be ± 100m, the accuracy requirement of seismic exploration contentedly.
