摘要
采用关联分析方法对石油套管在复杂载荷下的破坏实验数据进行了关联分析。结果表明 ,外径和壁厚是影响套管径向极限承载能力的 2个主要因素 ;套管外挤压力对套管轴向极限承载能力的影响很大 ;椭圆度仅对均匀外挤压力导致套管破坏有较大影响。
Casing destructive testing data are analyzed correlatively under complicated loads by using a correlative analytical method The result indicates that outside diameter and wall thickness are two key factors influencing the casing radial limit loading capacity, the effect of outside casing squeeze pressure on its axial limit loading capacity is very big, the only effect of ellipticity on casing destruction caused by even outer squeeze pressure is higher
