摘要
针对滨里海盆地巨厚盐下复杂的地震资料,通过模型正演方法及具体实例,在垂直地震测井(VSP)及盐层速度分析的基础上,剖析了盐下假断层、假构造的形成机理与校正方法,在滨里海盆地中区块地震资料精细解释中取得了较好的效果。
Based on the eo,nplicated seismic data from huge-thick sub-sah carbonate rocks in Pre-Caspian basin, this paper analyzes the formation mechanism of sub-sah pseudo-fauhs and pseudo-structures and presents related enrrection method through foard modeling and fiehl eases, integrated with vertieal seismic profile （VSP） and salt bed velocity analysis. And better results are obtained for refined interpre- tation of seismic data from the eentral block in this basin.
