Research on the Mechanism and Suppression Method of Gas Migration Velocity Under Gas Invasion Conditions in Ultra‐Deep Well Drilling

open access: yesEnergy Science &Engineering, Volume 14, Issue 1, Page 460-474, January 2026.
ABSTRACT During ultra‐deep well drilling, the narrow safety density window of the drilling fluid makes it prone to complex conditions such as gas invasion. The high‐temperature and high‐pressure environment causes changes in the properties of the drilling fluid, making the gas invasion process highly covert and increasing the difficulty of well control.
