【摘要】 曲线重构是提高储集层与围岩速度差异不明显地区测井约束地震反演效果的有效技术。利用多维网格法进行曲线重构是提高重构曲线质量的有效方法,该方法通过建立多维网格数据库,在通过曲线标准化后的声波曲线和自然伽马曲线、密度曲线等相关性比较好的一系列曲线中建立关系,并利用克里格方法进行拟声波曲线的重构,增加了重构曲线反映地层的信息量,从而提高了利用重构曲线划分储集层的质量。更多还原

【Abstract】 Curve rebuilding is an effective approach used in improving the quality of seismic inversion in areas where the velocity difference between reservoir and surrounding rock is not obvious.This paper suggests that multi-dimensional grid method is promising.Relationships were established between acoustic curve and a series of curves such as natural gamma and density curves.Kriging method was used for rebuilding of acoustic curve.The resulted curve could be used for classifying reservoir.更多还原
