Abstract In order to resolve the problems of hole shrinkage, bit balling and borehole instability in
mudstone section of the Xinjiang Tahe Oilfield, a new polyamine drilling fluid was applied in section 2 and
scction 3 of Well Dul 4. Laboratory test shows that the new polyamine drilling fluid system has strong in
hibition and good lubrication property. Its application in section 2 of Wel! DUII 4 effectively solved sticking
and bit balling problems in the mudstone section, preventing any complications, resulting in the reduction of
15 days in drilling cycle than offset Well DUH 1. In section 3 of the Well DUH 4,it has solved the problems
of borehole instability and tight holes caused by complex hydration swelling of gypsum mudstone and
shale, the drilling cycle time was 50 d shorter than Well DUH 1, and average hole enlargement rate was only
4.37%. The successful application of novel polyamine drilling fluid in Well DUH A shows that the drilling
fluid can effectively solve tight hole and bit balling in mudstone rocks, ensure the safe drilling, reduce drill
ing cycle time, and improve drilling efficiency
