摘　　要：介绍了丘陵油田地层、岩性特点及易发生的井下复杂情况。在上部地层选用两性离子聚合物钻井液、中下部地层选用聚磺钻井液。经现场应用表明,两种钻井液抑制能力、防塌能力、携砂能力强,润滑性好,性能易于维护。两种钻井液能满足相应井段的钻井施工需要,避免了井下复杂情况的发生,实现了丘陵油田长裸眼安全钻井。Formation character and drilling problems in Qiuling oil field are introduced. Amphoteric polymer mud and polymer mud with sulfonated additive are used respectively in top and bottom formation. Applications in 194 wells indicate that these two drilling fluid systems possess the advantage of good inhibition ability , hole sloughing resistance, sand carrying ability, good lubricity and can satisfy the demand of drilling operation.
