摘　　要：针对南阳凹陷张店区块的地质特征及长裸眼大斜度定向井对钻井液的特殊要求,优选了聚合物防塌润滑钻井液体系,并制订了相应的维护处理措施。介绍了2口井的应用情况及效果。实践表明,选用的聚合物防塌润滑钻井液体系悬浮携带、护壁防塌和润滑防卡能力强,避免了井下复杂情况的发生,能够满足长裸眼大斜度定向井的施工需要。Based on the geological characteristic of Zhangdian block in Nanyang oilfield and requirements of long openhole and high-angle directional drilling, a sloughing prevention drilling fluid is optimized. The matching treatment and maintenance are also investigated. Applications and effects are introduced. The advantages of the fluid such as good cutting transportation, sloughing prevention and lubrication are proved.
