| Abstract | 本实用新型提供了一种与底部钻具组合配合使用的单极随钻声波测井仪。与底部钻具组合配合使用的单极随钻声波测井仪中的底部钻具组合包括钻铤和钻头，钻铤的端部上安装钻头，钻铤上连接的单极随钻声波测井仪包括：安装在钻铤上的声波接收器；安装在钻铤上的单极子声源，并且单极子声源发出预定频率范围的声波；单极子声源与声波接收器之间由隔声体连接；钻铤的外直径D1与钻头的外直径D2的比值为d，则0.75＜d＜1。应用本技术方案能够解决现有技术中存在的对于慢地层横波速度测量，需同时使用单极子测井和四极子测井来分析地层纵波与横波速度，操作过程与数据处理复杂导致测量精度不高和效率降低的技术问题。 |
| Other Abstract | The utility model provides a monopole acoustic logging while drilling appearance with bottom hole assembly cooperation use. Bottom hole assembly among the monopole acoustic logging while drilling appearance with bottom hole assembly cooperation use includes drill collar and drill bit, installs the drill bit on the tip of drill collar, and the monopole acoustic logging while drilling appearance ofconnecting on the drill collar includes: install the sound wave receiver on the drill collar, install the monopole sound source on the drill collar to the sound wave of preset frequency scope is sentto the monopole sound source, be connected by the acoustic isolater between monopole sound source and the sound wave receiver, the external conjugate diameter D1 of drill collar and the external conjugate diameter D2's of drill bit ratio is d, then 0.75 < d < 1. Using this technical scheme and can solving measuring to slow stratum shear wave velocity of existing among the prior art, the well logging comes analysis stratum compressional wave and shear wave velocity with quadrupole need to use the monopole well logging simultaneously, and operation process and data processing complicacy lead tothe not high technical problem with the efficiency reduction of measurement accuracy. |
