井震联合反演在塔南凹陷储层预测中的应用

Application of seismic and logging joint inversion in reservoir prediction of Tanan depression

塔南凹陷是塔木察格盆地一个主力生油凹陷,针对塔南凹陷构造复杂、岩性多变等特殊地质条件,应用JA SON地震反演软件,将地震、测井、地质信息有机结合起来,采用地震-测井联合反演,通过对地震反演资料补充测井数据高低频成分、拟声波曲线的构建以及建立合理准确的地质模型,提高该区储层预测的纵向分辨率,加强对薄互层砂体的识别能力,提高储层预测的可靠性,落实有利圈闭。

Tanan depression is a main petroleum generative depression in Tamtsag basin.According to the special geological condition in Tanan depression,such as complex structures and rapid change of lithology,the technique of seismic and logging joint inversion was used combination with seismic、logging and geology information in JASON seismic inversion soft.Though supplement logging data with high and low frequency components、integrate pseudo-acoustic curve and establish accurately geological model,enhance the vertical resolution in reservoir prediction and the recognition capability of sand body,these way improve the reliability of reservoir prediction and fix prospective lithologic traps.
