摘要
针对常规随钻测井存在的技术局限问题,介绍了UTE方位伽马近钻头测量系统的组成及原理,并通过现场应用,证明了UTE方位伽马近钻头测量系统能够通过近钻头井斜和方位伽马进行精确的地质导向,及时掌握所钻地层岩性变化,提高了在薄目的层中井眼轨迹控制能力和目的层钻遇率。
Aiming at the technical limitations of conventional logging while drilling,the structure and principle of UTE azimuthal gamma near-bit measurement system are introduced.Through on-site application,it is proved that the UTE azimuthal gamma near-bit measurement system is able to carry out accurate geosteering by means of the near-bit inclination and azimuthal gamma,grasp the change of lithology of drilled formations in a timely manner,and improve the ability of trajectory controlling of the well borehole and the drill-in rate to the target layer.
