| 摘 要： | 传统的单极声波测井仪只能测量地层的纵波波速,且有其自身的缺点。对于硬地层来说,可以通过对长源距声波全波测井资料的分析、处理,获得纵、横波波速,但在软地层中无法获得横波速度。通过偶极声波测量技术可以测量地层的横波,进而计算岩层弹性及非弹性参数、地应力参数、孔隙度、渗透率等,使声波测井曲线提供的有用信息量骤增。文章从电路入手,分析了在青海油田偶极声波仪在应用中出现的问题,总结了解决方法。

| Abstract: | Traditional acoustic logging tool only measures the velocity of compressional wave of the formation,and has its own shortcomings.For hard formation,compressional wave(P-wave)and shear wave(S-wave)velocities can be obtained by the analysis and processing of long-distance full-wave acoustic logging data,however,in soft formation,S-wave velocity can not be obtained.Shear wave velocity can be measured by wavesonic logging technology,and as a result,the elastic and inelastic parameters of the rock,formation stre... |
