FLUID FLOW DURING LANDING OF LOGGING TOOLS IN BOTTOM HOLE ASSEMBLY

摘要

The present disclosure relates to systems, assemblies, and methods for facilitating fluid flow during/after landing of logging tools in a bottom hole assembly. In operation, a memory logging tool is lowered through a longitudinal bore of a drill pipe string and landed in a bottom hole assembly disposed at the end of the drill pipe string. Drilling fluid is pumped behind the logging tool to assist with downward movement of the tool. As the logging tools land, partial fluid flow path is blocked by the logging tools. The fluid pressure can rise in response to the narrowing of the fluid flow path. Facilitating fluid flow through and/or around the logging tools can put the rising fluid pressure in a proper range for powering the logging tools to land and monitoring purposes.
