The geometry modification design of the seismic prospecting acquisition is necessary in the seismic acquisition.It involves many subjects,like geophysical,math,computer graphics,and parallel computing technology and so on.Under the normal computer environment in filed seismic acquisition,how to change the geometry system efficiently is the key in the high density and high precision seismic prospecting acquisition.Druing the processing of geometry modification design,SPS data,bin segmentation,precise correction of the satellite or remote sensing photos,parallel computing technology are the key factors which decide the efficiency of the seismic prospecting.Nowadays,seismic prospecting method based on the massive data and high efficient acquisition is the mainstream method,but the software used now is unable to meet the need of nowadays seismic prospecting.In order to increase the efficiency geometry modification design,this study starts from the four key factors mentioned above.Firstly,we analyzed the format of the SPS data.Through analyzing the properties of the format,a project to locate the massive SPS data rapidly has been proposed,and we also proposed automatic adaptive bin segmentation and attribute parallel computing technology of 3D seismic geometry,and established the processing flow.Secondly,puts forward the image processing technology for seismic geometry-changed design,and establishes the processing flow of precise correction,coordinate registration and image enhancement processing flow.Thirdly,proposed the concept of layer organization,used the Interpolation and thinning technology,and adopted the multi-threading parallel processing to realize efficient display and analysis of the geometry system and has been formed the engineering application process.Finally,using the plug-in technology provided by the open S software platform,the integration of the above technology is realized.It has solved the problems of high efficient storage,processing and display of large amount of data,multi-type data and various graphics and images,and realized the geometry-changed design based on the complicated seismic acquisition and massive data on ordinary computer.It is innovative in adaptive panel block parallel computing,geometry-changed design based on satellite registration and precise correction,multilayer geometry attribute using multi-threading parallel processing technology and so on.
