DISCUSSION ON BORE HOLE WALL STABILITY

    Graphical Abstract
    • Abstract
  • In order to realize optimized design on drilling fluid prpperties, bore hole structure and other parameters, a comprehensive analysis on bore hole wall staility in directional wells from point of view of rock mechanice, geophysical logs, engineering data collection, annulus hydraulics and drilling fluid chemistry was conducted and formation prore pressure profile, formation sloughing profile and formation breakdown pressure profile were established.
