偶极声波测井技术自投入使用近30年来,以其在横波测量、横波各向异性分析方面的独特优势使其在测井、地震、地质、油藏工程各方面得到了广泛运用.偶极声波测井资料包含的纵波、横波、斯通利波等诸多储层声学信息,通过时差提取、能量计算、横波各向异性分析、岩石力学参数计算等处理过程,能够有效解决储层流体性质判别、地应力方向确定、裂缝分析、储层改造评价等诸多现实问题,提高了声学测井资料解决油气地质及工程问题的能力.本文简要回顾了偶极声波测井技术的发展历史,详细论述了其目前在国内外的应用现状,并对其在仪器设备、探测模式及数据处理方面的技术进展及研究方向进行了简要分析说明和讨论.
Dipole sonic logging has been widely used in logging, seismic, geological and reservoir engineering since it was put into operation for nearly 30 years because of its unique advantages in shear wave measurement and shear wave anisotropy analysis. Dipole Acoustic logging data contains many reservoir acoustic information such as P-wave, S-wave and Stoneley waves, which can effectively solve the reservoir fluid property discrimination through time-difference extraction, energy calculation, shear wave anisotropy analysis and rock mechanics parameter calculation , The determination of direction of stress, crack analysis, evaluation of reservoir reconstruction and many other practical problems, improve acoustic logging data to solve the problem of oil and gas geology and engineering capabilities.This paper briefly reviews the development history of dipole acoustic logging technology, discussed in detail At present, it is applied at home and abroad, and briefly analyzes and discusses its technical progress and research direction in equipment, detection mode and data processing.
