【Abstract】 In order to improve the ability of solving geological problems by conventional logging information,this paper based on extensive literature research and analysis,combed the basic principles and properties of S transform, and summarized research results that the current S transform was used for data processing of seismic.Analysis and prospect these possible aspects that the S transform was used for the information processing of logging,The study shows that S transform is a signal processing method with high time-frequency resolution.In seismic data processing,S transform can be used to these aspects,such as,the initial identification of seismic wave,the denoising of seismic signal filtering,the division of sedimentary cycle based on seismic information,the identification on cavern reservoir of carbonate reservoir and the analysis of seismic fancies,etc.In the conventional logging information processing,S transform can be used to these aspects,such as,the de-noising of log presentation,the research of sequence stratigraphy,the identification of the properties on reservoir fluid and the identification of low permeability sandstone reservoirs cracks.The S transform was introduced into conventional log information processing,which can effectively promote the solution related to geological problems in oil exploration and development.更多还原
