摘要
超短半径水平井近年来成为边际油藏高效开发的重要措施。通过分析超短半径柔性钻具受力特性,探究柔性钻具在轴向压力、轴向拉力、径向扭矩和径向弯矩不同力学载荷下的形变趋势,为柔性钻具的设计改进提供参考。
In recent years,ultra-short radius horizontal wells have become an important measure for efficient development of reservoirs.By analyzing the mechanical characteristics of ultra-short radius flexible drilling tools,this paper explores the deformation trend of flexible drilling tools under different mechanical loads of axial pressure,axial tension,radial torque and radial bending moment,providing reference for tool design and improvement.
