ABSTRACT = {The ash mudstone in some oil formations is highly water-sensitive. The oil formation is fractured, and the risk of
well leakage and collapse is not negligible. This study presents a countermeasure for well collapse prevention,
based on a “force-chemistry synergistic balance” approach and the utilization of environmentally friendly and
efficient hydration inhibitors. The relevance of this approach is demonstrated considering a drilling fluid system
with the high potassium content. The analysis shows that the system can maintain good rheological properties,
filtration loss and suspension stability even after aging at 130°C for 16 h. The primary roll recovery of rock chips
is better than 98%. The secondary rolling recovery rate is 89%. The rapid water loss is close to zero. The effects of
carrying rock, sand, hydration inhibition and dispersion of drill chips are all noticeable.},
