With the improvement of the production and manufacture technology of casing, the actual collapse strength of casing cannot be accurately calculated by present API 5C3 formula.───随着套管制造工艺水平的不断提高和制造质量的显著改进,现有的API 5C3公式已不能正确的预测套管实际抗挤抗内压强度。
With finite element method, the collapse strength of casing with ovality and eccentricity under unidirectional uniform and ellipse distributive force was calculated and analyzed.───采用有限元法,计算和分析了壁厚不均与椭圆套管在单向均匀和单向椭圆分布外挤力作用下的强度问题。
improved model is used to calculate the final casing collapse strength. This method combines FEA and strain test together and thus can get more …───该方法将有限元计算与应变检测结合起来,大大提高了有限元计算的精度,对预测套管的挤毁压力、指导高抗挤套管的开发具有一定的参考价值。
The results showed that the casing collapse strength and internal pressure strength will decrease as the casing wear-thickness increases.───计算结果表明,非均匀磨损套管的抗挤强度和抗内压强度降低百分比随套管磨损厚度的增加而增加;
Under the same wear condition, the casing collapse strength decreases more rapidly than the internal pressure strength.───在相同的磨损厚度情况下,磨损后套管的抗挤强度比抗内压强度降低得更快;
