摘要
建立了大斜度定向井及水平井起下钻过程中钻柱摩擦阻力微分方程，并推导得到钻柱摩阻的解析解。采用计算公式对长庆油田塞平－１水平井所用典型钻柱结构的摩阻进行了理论预测，预测结果与现场实测数据较吻合，验证了理论模型的合理性。
The differential equation for the frictional resistance on the drillstring during tripping in high-deviated holes and horizontal holes was established. The frictional resistance obtained theoretically by the above-mentioned equation accords with the in-situ measured data.
