摘要
基于悬臂梁模型,建立了旋转导向偏心稳定器在提离井底条件下的力学模型,分析了偏心稳定器产生的造斜力与钻具横向均布载荷、井斜角、钻具长度、偏心位移以及钻具抗弯刚度等参数的关系,其结果可以为旋转导向钻井工具的设计和钻具组合的选配提供依据。
Based on cantilever model, the mechanical model is built to analyze the relationship among the deviating force generating from eccentric stabilizer with the horizontal uniform load of drilling tool, deviation angle, length of drilling tool, eccentric displace and bending rigidity of drilling tool as lifting off downhole. The results can provide the evidence for design of rotary steering drilling tools and selection of drilling string.
