Abstract: Based on the formation-on-bit drag torque model and the theory of anisotropic deflecting by formation, this paper deals with the influence of the bit, drill string, formation and drilling parameters an threedimensional buckling of lower drill string in a deviatied-straight borehole.

摘要： 根据地层对钻头的反抗扭矩模型和地层各向异性造斜理论,合考虑钻柱、钻头、地层及钻井参数对斜直井内下部钻柱空间弯曲变形的影响。
