摘要
常用的投球式和液压式丢手工具因存在施工效率低和不能传递扭矩等特点而限制了应用范围。针对这种情况 ,研制出KDS— 115型液压丢手工具。该型工具通过设置上接头与打捞头之间的凸爪凹槽结构 ,解决了以往丢手工具不能传递扭矩的问题 ;在结构设计上避免了工具承拉和丢手剪切受力零件相同 ,保证了工具的可靠性 ,丢手压力更易控制 ,具有抗拉强度高、承压能力强、能传递较大扭矩、适合于深井卡堵水作业等特点。新工具应用于卡堵、选层酸化管柱和不压井起下管柱及水平井作业中 ,能简化管柱结构 ,降低作业难度和成本 。
The commonly used releasing tools cannot carry out torque transfer, therefore its application is restricted.Model KDS-115 hydraulic releasing tool is developed, which solves the problem of torque transfer by designing a claw-groove structure between the upper sub and fishing head. The new tool has high tensile strength and can transfer large torque, and is suitable for using in water shutoff operation in deep wells. The operating principle of the tool is described and its application is introduced.
