摘要
综合考虑了钻柱的重力、井口部的提升力及钻柱的转速等三个主要方面对钻柱弯曲变形的影响,建立了动力学模型和方程,并以实例验证了本研究方法的可靠性。对钻井技术的理论研究和预防钻柱失效具有指导意义。
The paper comprehensive study three respects： the influence upon bending deflection caused by three primary aspects such as gravity, pull of the mouth of well and rolate speed of drillstring. Based on these the dynamic model and equatiou is established, and the reliability of the study method in the paper is validated by example. The method in the paper is of guiding significance for the theory study of drill technique and perverting drillstring from failure,
