Realization of 3D Simulation Technology in Quality Control for Seismic Data Acquisition
摘要
Under today’s complex earth surface conditions, factors influencing the quality of seismic data acquisition are mainly found in hypocenter excitation or seismic wave reception. This, however, often leads to the excessive pursuit of details or one-sidedness, and lack of mastery of the whole work area. In this paper, the 3D images for a work area is constructed by using satellite photos and digital elevation model, and then, according to geodetic coordinates of the shots, the quantitative shot evaluation parameters, including signal-to-noise ratio, shot energy, resolution and the fusion of these three parameters, are accurately superposed onto the 3D image, and the 3D simulation in quality control technology for seismic data acquisition is realized. The advantages of this technology lie in that it not only shows the distribution pattern of shot quality evaluation parameters, but also helps people easily find the influences of the earth surface conditions on the shot quality by using satellite photos, thus improving the quality control for the field seismic data acquisition.
