GEEnergy公司开发了一种新型电阻率系统。这种井下电阻率系统在井眼正钻时提供地层评价资料。与电阻率测井仪一同使用的MWD探头 ,安装在电阻率测井仪的上面 ,以便回收并将资料传输到地面。电阻率测井仪把多个发射器的间距和单独的频率结合起来 ,从而自动弥补了井底温度和压力的
GEEnergy has developed a new resistivity system. This downhole resistivity system provides formation evaluation data as the wellbore is being drilled. The MWD probe used in conjunction with the resistivity tool is mounted above the resistivity tool to recover and transmit the data to the surface. Resistivity tools combine the spacing of multiple transmitters with individual frequencies to automatically compensate for the bottomhole temperature and pressure
