直接使用横波测井已经成为油气勘探开发中重要的手段。针对高频散的挠曲波 ,将基于模拟退火的优化方法引入阵列偶极子测井资料处理中 ,以得到横波时差。该方法与常规的速度求取方法不同 ,它不仅采用接收器阵列组合 ,而且采用单个源接收器在不同深度的组合。此方法也提供了一种在整个井段定量地得到相对置信度的方法。应用此方法处理了辽河油田 5 70 0横波测井数据 ,并与横波慢度的常规估计方法进行了对比 ,结果表明 ,此方法比常规的相关分析等方法更可靠
The direct use of S-wave logging has become an important tool in oil and gas exploration and development. For the highly deflected bending wave, an optimization method based on simulated annealing is introduced into the array dipole logging data processing to obtain the transverse wave time difference. This method is different from the conventional method of speed estimation. It uses not only the receiver array combination but also a single source receiver at different depths. This method also provides a way to quantitatively obtain the relative confidence throughout the interval. Using this method, the 5 70 0 shear-wave log data from Liaohe Oilfield was processed and compared with the conventional method for the slowness of shear wave. The results show that this method is more reliable than the conventional correlation analysis
