摘要
在油田生产过程中,油管偏磨现象十分普遍。通过对油管的受力分析,校核偏磨油管的抗拉强度和抗疲劳强度。进行偏磨油管抗内压强度计算,确定油管发生偏磨后内径变化的极限值。为生产实践过程中油管的使用和管理提供可借鉴的技术参数。
During field production,the phenomenon of eccentrically worn tubing is often met.By analyzing the force applied on the tubing,the tensile strength and anti-fatigue strength of the tubing are calibrated.The anti-internal-pressure strength is calculated for the eccentrically worn tubing to determine the limit of inner diameter changes of the tubing,by which technical parameters are provided for the tubing application and management in field production.
