摘要
声波曲线是目前进行基于测井约束的波阻抗反演工作所必备的基础资料,然而在实际工作中得到的声波资料经常不能很好地反映地下岩性的变化规律,因此有时需要参考其它测井信息进行曲线重构工作。该文结合LMZ地区的波阻抗反演实例,介绍了一种曲线重构方法,主要包括曲线整理、数据标准化、曲线分析和数据重构等步骤。
Abstract
Acoustic curves are basic data essential for the wave impedance inversion based on logging restraint. But the acoustic data obtained from practical work usually cannot well reflect the changing rules of subsurface lithology. So, it is needed sometimes to refer other logging information in order to do curve recomposition. Combined with the examples of wave impedance inversion in LMZ area, a curve recomposition method was introduced in this paper, whichincluding curve sifting, data standardization, curve analyses and data recomposition these steps.
