摘　　要：针对侧钻水平井中尾管与老井套管的搭接问题 ,分别对水泥环与内侧尾管、水泥环与外侧套管两个粘接面进行分析 ,根据套管柱与水泥环之间的粘结力在外部轴向载荷作用下不破坏的原则 ,确定了侧钻水平井尾管与老直井套管重叠搭接高度的理论模型 ,算例分析结果与现场经验数据基本吻合。The tail tube need to be connected with the casing of old vertical well in side track well. According to the principle of cohesive force not being destroyed between casing and cement, the theoretical model of overlap height is confirmed after analysing the paste surfaces of tail tube cement or cement casing in the action of axial load.
