Residual Strength Analysis of N80 Oil Tubes with Corrosion Defects
摘 要
针对N80油管腐蚀问题,使用APDL编程语言建立了剩余强度数值计算的参数化模型,模型可分析轴长型与短型两种缺陷形式。以某油田油井数据为背景,对比分析了腐蚀缺陷轴向长度、环向宽度、径向深度及油管轴向应力和内压对油管剩余强度的影响。研究成果可为含腐蚀缺陷油管的安全评估提供依据。
Abstract
A finite element model for the residual strength analysis of N80 steel oil tube with corrosion defects was built by the programing language APDL. Based on the actual data of an oil well an one actual oil field, the effects of the axial length, circumferential width and radial depth of the corrosion defect and the internal pressure and axial force on the residual strength of the tube were examined in detail. The proposed method can be referred in the safety evaluation for the oil tubes with corrosion defects.
