摘要
本文论述了利用声波全波列数字测井资料提取横波的两种方法:子波逼近法和相似相关法。根据测井获得的纵波、横波和密度资料,计算了岩石的弹性模量,所得结果有足够的精度,为煤矿生产和建设提供了有用的岩石物理力学参数。文中还讨论了用静态法和动态法所测得的弹性模量存在的某些差别。
Two methods are discussed in this paper for estimating shear-wave from full waveform acoustic logging records: wavelet-approach and semblance.The elastic mocule of rocks can be obtained with compressional-wave,shear-wave and density parameters from well logs.The result indicated that the precision is sufficient.This determination is very useful to supply the physical mechanics of rock parameters for coal-mining.The differences between measurements of elastic module of rocks in static and dynamic are also discussed in this paper.
