Drilling time will be lasted and lateral force on casing exerted by drill pipe will increase in case of drilling deep well, ultradeep well, high inclined hole, extended reach well and horizontal well, therefore, friction and wear between casing and drill pipe became a severe problem
在深井、超深井、大斜度井、大位移井及水平井中，鉆井時間延長、鉆柱作用在套管上的側向力增高，因此套管和鉆柱的摩擦與磨損問題越來越突出。Based on the dynamics, a mechanical model calculating the drill string ' s eccentric wear is established, the approximation equation calculating the positive pressure on casing / drill string is derived out, and the major factors affecting the eccentric wear are analyzed
針對深井鉆井中的井口附件套管偏磨問題，以動力學為基礎，建立了鉆柱偏磨力學模型，推導出了套管鉆柱正壓力的近似計算公式，分析了影響偏磨的主要因素。
