The Key Technologies of High Precision Imaging Logging while Drilling

  • 摘要:

    为了解决随钻地质导向系统距离钻头远、检测信息少和检测精度低的问题,基于随钻扇区扫描原理,结合MEMS动态工具面检测技术、近钻头伽马旋转累计计数成像采集算法和随钻电阻率动态PID调节发射驱动成像采集算法,研制了高精度近钻头伽马成像测井仪和高精度随钻电阻率成像测井仪,实现了近钻头伽马16扇区测量与随钻电阻率128扇区测量。现场试验结果表明:随钻采集到的近钻头伽马成像测井数据可为复杂油气藏地质导向钻进提供技术支持;随钻电阻率成像测井数据与电缆测井数据吻合,可为随钻地层评价提供可靠数据。研究表明,利用近钻头伽马成像测井仪和高精度随钻电阻率测井仪可以获得高精度的测井数据,为地质导向和地层评价提供支持。
