摘要: 介绍了利用正交阵列偶极子声波测井资料反演地层横波各向异性的计算过程,研究了极快速模拟退火算法在阵列偶极子声波波形反演处理中实现全局寻优的方法。利用基于极快速模拟退火算法自主编制的软件对多口井的正交阵列偶极子声波测井资料进行了处理。结果表明,极快速模拟退火算法无论是在计算精度还是在计算速度上都达到了对阵列偶极子声波进行波形反演的要求,可以用于正交阵列偶极子声波测井资料的实际处理。

Abstract: The waveform inversion method for computing shear wave anisotropy of formation in the cross-dipole acoustic-array logging was introduced. This method is based on the very fast simulated reannealing (VFSR) to evaluate shear wave anisotropy. The global optimization search speed of this method is faster than that of other reannealing algorithms. The data from several wells were intensively processed using the software made upon the VFSR. The results indicate that this algorithm can meet the need of computing accuracy and computing speed in the waveform inversion. This method can be used in practical data processing of cross-dipole acoustic-array logging.
