Description
The present invention relates to a kind of seismic physical modeling technology, relate to a kind of data collector and method that is used for seismic physical modeling or rather.
The research of seismic physical modeling starts from abroad the earliest, nineteen twenty-seven, Terade and Tsuboi agar, promptly a kind of jelly was made a seismic physical model, make focus with electromagnetic pulse, observed such as the situations such as influence of seismic event with tomography and river course on the variation of the degree of depth and the round.1970, Hilterman.F.J. utilized electric spark to make focus, was converted into difformity with paper and simulated different tectonic structures, write down anticline, to architectonic self-excitations such as oblique, folds from being subjected to record.Early stage experiment mainly launches around tectonic model, comprises the model of some simple two-dimensional even one dimension, verifies some simple questions.
As time goes on, the seismic physical modeling technology is constantly developed, as 1997, houston, u.s.a university built up in the seismoacoustics laboratory tank seismic physical model system, and became the basic model of each laboratory seismic physical modeling system of the present world.
A kind of seismic physical modeling is located the basic structure of acquisition system automatically shown in Fig. 1, what adopt is that habitual single-point excites the single-point receiving mode in the seismic physical modeling experiment both at home and abroad at present, and its collecting device comprises: geologic model 101, tank propagation mediums such as (or) platforms 102, excite transducer (exciting probe) 103, receiving transducer (receiving transducer) 104, ultrasonic vibration source 105, location acquisition control system (microcomputer) 106, high speed data acquisition system 107, amplifier 108, prime amplifier 109, positioning system 110 and positioning control driver element (single-chip microcomputer) 111.111 of ultrasonic vibration source 105, location acquisition control system (microcomputer) 106, high speed data acquisition system 107 and positioning control driver elements (single-chip microcomputer) are connected by IEEE-488 interface bus 112.
According to tectonic structure design geology physical model 101, be immersed in this geology physical model 101 in the tank 102 or be placed on the platform, the pulse producer of ultrasonic vibration source 105 sends spike pulse, deliver to and excite transducer 103, the transducer of being made by the piezoelectric ceramics that excites in the transducer 103 is converted to ultrasonic emitting with electric pulse.Receiving transducer 104 receives through 101 reflections of geology physical model and through the sound wave that transmission medium is propagated back to, and is converted to electric signal, and further send high speed data acquisition system 107 to carry out acquisition and recording through prime amplifier 109, amplifier 108 after amplifying.
At present the method for work of seismic physical modeling is: given an order to positioning control driver element (single-chip microcomputer) 111 by location acquisition control system (microcomputer) 106, positioning control driver element (single-chip microcomputer) 111 110 pairs of positioning systems of control excite transducer 103, receiving transducer 104 carries out running fix, send the signal that drives ultrasonic vibration source 105 by location acquisition control system (microcomputer) 106 then, repeat to excite transducer 103, the emission ultrasound wave is to geology physical model 101, along with exciting transducer 103 each time, 100 pairs of receiving transducers of positioning system 104 carry out a running fix, receiving transducer 104 receives reflection wave and converts electric signal to, the signal of 107 pairs of receptions of high speed data acquisition system carries out digitized processing, finally is recorded on the hard disk by standard format by location acquisition control system 112.
Because positioning system 110 has only two arms that are connected with the receiving transducer that excites probe and receiving transducer 104 that excites transducer 103 respectively, data of every reception, just need excite and once excite probe, control positioning system 110 simultaneously once, once gather a track data for high speed data acquisition system 107 with the receiving transducer running fix in the receiving transducer 104.Because during total system work, excite that probe repeatedly excites, constantly repeatedly mobile receiving transducer simultaneously, and the whenever mobile arm of positioning system 110 all needs the long period, thereby the most working time all has been used on frequent the moving of positioning system 110, caused in the very long situation of the data collection cycle of laboratory geophysical model, the data volume of required collection is very big in addition, makes an acquisition tasks often need some months just can finish, and collecting efficiency is quite low.In addition, frequent the moving of positioning system 110 causes mechanical wear to increase, and also had a strong impact on the operation life of system.Therefore, can think: the key issue that influences laboratory geophysical model acquisition speed is exactly that single probe receives.
In order to adapt to the more and more difficult situation of problem that exploration object and development environment that the work of China's oil natural gas exploration and development deepens continuously, faces become increasingly complex, will solve, need higher experimental technique, the seismic physical modeling of 3-d seismic exploration and particularly based on the optimal design of the stereo observing system of geologic geophysical model, the three-dimensional acquisition data volume is bigger, and obviously present single track data acquisition efficiency can not address that need.
