Abstract：There are more and more high density and large trace number(3D) seismic exploration application,which brings new challenge for the field seismic acquisition,for example the current SPS software does not support large trace number acquisition.The SPS file preparation method for over ten thousand trace in seismic exploration was discussed in this paper,at first the difference between the conventional SPS file format and the SPS file format for over ten thousand trace was compared,then the problem for using the conventional SPS file format in acquisition for over ten thousand was analyzed,thirdly the SPS file format was analyzed and summarized,and fourthly the development and realization of the SPS file preparation software for over ten thousand trace were introduced,and at last the SPS file preparation software for over ten thousand trace was used in field seismic data processing,great results were achieved with the method.
