Study Of Application Of The Land Seismic Geophone

As the development of technology of geophysical prospecting and the extension of prospecting scopes, especially the application of technology of high resolution prospecting and study of Q technology and the lithology prospecting, the requirement of the quality of seismic data is higher and higher, namely is low distortion,high S/N ratio and wide band etc. The quality of seismic data is decided by the specification of the data acquisition system mainly. The data acquisition is combined with instrument and geophone, as the development of electronic technology, the specification of instrument is better than the geophone's, as the result that the quality of seismic data is decided by the specification indeed. So the study of application of geophone is useful. Facing all kinds of analog geophone and fresh digital geophone, it is the final goal of geophysical prospecting to improve the quality and efficiency of wild productions with the proper application and management of geophone, so many technicians from BGP work together to study the application of geophone. The main tasks of this project are to study the theory ,structure,advantages and disadvantages of analog/digital geophones, and to finish some experiments in wild field ,the technicians analyse the results of experiments, and finally they give some advises and suggestions on how to use and manage the geophone in wild field as follows. In recent years, many people finish the study of geophone, but most of them just repeat the past experiments, do not do it on the basis of theory, especially in the coupling between geophone and ground. Finally this paper gives some suggestions on further study. First it is that the data processing technology must be enhanced; second, the coupling technology must be broken. Some viewoints of this project is leading in the prospecting field, such as the theory and application technology of MEMS geophone,the choice of natural frequency of analog geophone, etc, that will guide the application and research of he geophone. of course some of them have the limitation and it must be perfected with the development of prospecting technology.
