引言自石油勘探进入地震地层学时代以来,要求勘探学家更详尽的研究地质情况的变化,在成熟探区尤为如此。但是,对地球物理学家的这一要求,因地震子波的分辨力所至,迄今仍为难题。近来,分析地震数据已有可能揭露构造和地层中的小量的变化,发展了一种定量解释技术,以补偿子波分辨力的不足,甚至可提供有关薄层的厚度及横向延伸范围等信息。 INTRODUCTION Since petroleum exploration entered the era of seismic stratigraphy, exploration scientists have been required to study in more detail the changes in geological conditions, particularly in mature exploration areas. However, this requirement for geophysicists is still a problem to date due to the resolving power of seismic wavelets. Recently, the analysis of seismic data has made it possible to expose minor changes in tectonics and formations, and a quantitative interpretation technique has been developed to compensate for the lack of resolution of the wavelet and even to provide information on the thickness and lateral extent of the sheet .
