摘要
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 acoustic logging technology has come into service nearly 30 years,with its advantages of shear wave measurement and shear wave anisotropy analysis,it＇s widely used in well-logging,seicmic,geology and petroleum reservoir engineering and other project fields. The compressional wave,shear wave,stonely wave and the other reservoir acoustic informations contained in the dipole acoustic logging data could effectively solve many practical problems such as reservoir fluid property discrimination, stress direction determination, fracture analysis, reservoir fracturing evaluation through the prosessing of wave slowness extraction,wave energy calculation, share wave anisotropy analysis, rock mechanic parameters calculation,etc. It improves the capacity of acoustic logging in solving petroleum geology and engineering problems effectively. The application status of dipole acoustic logging at home and abroad is stated in detail in this paper, and the newlydeveloped technology and development direction of the actual equipment,detection mode and data processing is analyzed and discussed briefly.
