发明名称 ORIENTING DOWNHOLE TOOLS
摘要 A method and apparatus of orienting a tool in a wellbore includes running an orientation string into the wellbore, the orienting string including a positioning device, a measurement device (e.g., a gyroscope), and the tool. The orientation string is positioned in a predetermined interval in the wellbore. The azimuthal orientation of the orientation string is measured with the measurement device. The orientation string is removed from the wellbore, and a tool string is run into the wellbore, the tool string including substantially similar components as the orientation string such that the tool string follows substantially the same path as the orientation string.
