eccentric wear meaning in English

（轮胎）偏磨耗
偏心磨损

Finite element analysis of the influence of casing eccentric wear rate on collapsing strength
套管偏磨曲率对其抗挤毁强度影响的有限元分析
The technology mentioned could prolong the service life of old pipe , reduce eccentric wearing , and extend the wax removal cycle
对延长旧管使用寿命，减少杆管偏磨，延长油井清蜡周期具有良好的效果。
Since the deeper the well , the higher the lifting force at the upper drill string , the deviation of derrick and the well head ' s eccentricity should be avoided by all means to prevent the severe eccentric wear on the casing which is caused by excessive effective eccentricity
由于上部钻柱的提升力随井深的增加而增加，因此应当尽量避免井口偏心或井架安装不正，防止有效偏心距过大而造成近井口套管的严重偏磨。
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
针对深井钻井中的井口附件套管偏磨问题，以动力学为基础，建立了钻柱偏磨力学模型，推导出了套管钻柱正压力的近似计算公式，分析了影响偏磨的主要因素。
