METHOD FOR ALIGNING MWD TOOL USING ORIENTING HANGER ASSEMBLY

摘要

Methods are disclosed for deploying a retrievable MWD tool in a non-retrievable environment and aligning a selected orientation of an MWD tool, as deployed in a bottom hole assembly (BHA), with a selected orientation on a tool face on the BHA. Preferred methods include providing an orienting hanger assembly (comprising a tubular inner hanger, a tubular outer collar, and a tool adapter) and attaching an MWD tool to the tool adapter. The outer collar is inserted into a BHA and the selected tool face orientation is marked on the outer collar. The inner hanger is rotated within the outer collar to align (via the alignment notch) the high side of the MWD tool to the tool face orientation transferred onto the outer collar. The inner hanger is locked to the outer collar.
