HDD Performance Analysis on Screw Drilling Tools with Uniform-thickness Stator

摘要

The development of screw drilling tools plays an important role in the directional drilling industry.With the increasing market share of directional drilling,especially for HDD projects where screw drilling tools are employed for HDD pilot drilling,lots of screw products emerge every year and it leads to complex tools selection.This paper focuses on performance analysis which compares screw drilling tools of uniform-thickness with normal ones in order to provide engineers with the technical reference needed for HDD drilling tools selection.
