井下的摩阻和扭矩是大位移井设计和施工的两个关键因素,本文阐述了针对古巴大位移井的现状,研制径向振动工具来减低摩阻和扭矩,提高大位移井的施工质量,提高钻具的使用寿命,完善大位移井钻井工艺技术。详细介绍了径向振动工具的结构、性能。通过现场试验数据表明径向振动工具的使用可以有效地降低钻具的扭矩和摩阻,降低钻柱对套管的磨损。
Downhole friction and torque are two key factors in the design and construction of large displacement wells. This paper describes the current situation of large displacement wells in Cuba, develops radial vibration tools to reduce friction and torque and improve the construction quality of large displacement wells, Improve the service life of drilling tools, improve the drilling technology of large displacement wells. Details the structure and performance of radial vibration tools. The field test data show that the use of radial vibration tools can effectively reduce the torque and friction resistance of drilling tools and reduce the wear of the drill string on the casing.
