| Popis: | The article outlines the prerequisites and results of using a specialized technology for processing vibrograms obtained during high-performance vibroseismic studies using the “slip-sweep” technology. The goal is to reveal the potential and advantages of multispectral adaptive data processing, mainly associated with improving the quality and information content of the results obtained. The prerequisites for the introduction of technology are the existence of an objective demand for high-performance seismic exploration methods and the physical feasibility, in modern conditions, of recording and processing data from the level of initial vibrograms. The work describes the advantages and disadvantages of the vibroseismic method and its high-performance modifications, provides a brief retrospective analysis of the topic of processing vibrograms before correlation, substantiates specific methodological approaches to reducing the technological noise of vibroseismic “slip-sweep” surveys, demonstrates specific examples of improving data quality (both at the level of correlograms, and at the level of total sections) with different numbers of groups of vibroseismic sources. The main conclusion is that processing vibrograms using the “slip-sweep” method provides an increase in quality comparable to at least a one and a half to twofold increase in the shooting magnification. |
