【摘要】 现文采用灰色关联分析方法对石油套管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受极限承载力的 2个主要因素 ,套管外挤压力对套管受轴向极限承载力的影响很大 ;椭圆度仅对均匀外挤压力导致套管破坏有较大影响。更多还原

【Abstract】 The method of grey related analysis is used in the relational analysis of experimental data for petroleum casing wreck.The results show that the two major factors are outer diameter and thickness which influence axial limit load of casing.But the outer extruding force of casing is one of the maximum influential factors in influencing a pair of diameter limit forces.The ellipticity only influences casing damage caused by outer extruding force.更多还原
