Research on the Mechanism of Sand Bridge Stuck Drill in Deep Coal and Rock Gas Horizontal Wells
Accounting for wellbore collapse debris and the bulldozer effect, this study develops models for permeable and impermeable sand bridge sticking in deep CBM horizontal wells, deriving resistance and volume formulations. Validated in Changqing, results show impermeable bridges dominate; controls (fluid optimization, staged drilling, circulation, speed ...
