Analysis of Wellbore Instability Characteristics of Fractured Shale Formation under Thermal⁃Hydraulic⁃Mechanical⁃Chemical Coupling

Wellbore instability is easy to occur when drilling fractured shale formation. Based on mechanical experiments, this paper investigated the weakening law of mechanical properties of shale soaked in drilling fluid.Considering the influence of stress ...

Mechanism of wellbore instability and geomechanical control technology in strong Squeeze tectonic Zones—a case study of the Wuqia Tectonic Belt in Southwest Tarim

Aiming at the challenges of frequent wellbore instability and the failure of conventional anti-sloughing technologies in the Wuqia tectonic belt of Southwest Tarim, which are caused by strong compression, high-steep structures, and formation ...
