长源距声波测井资料分析处理

THE ANALYSIS AND PROCESSING OF LONG SPACING SONIC LOG

本文对长源距声波测井记录的波列特征进行分析,综述时域及频域处理信号的方法.阐明首波检测法、波形相似相关法、直接相位法的特点.讨论“软”、“硬”地层的不同特点,研究相应纵波、横波、管波的特征及其提取方法.并对“软”地层中管波速度反演横渡速度的模型进行了讨论.

In this paper, the characteristic of the long spacing sonic signature are processed and analized in both of the time and frequency domain. Describ the feature of the detection of the first arrivals, the correlation of wave form and phase angle. Discuss the characteristics of 'soft' and 'hard' formation and their correspouding compressional, shear and tube waves. The velocity of the tube wave and derivation of the velocity of the shear wave by using tube wave are also discussed.
