Experimental Study on High Collapse-Resistant Oil Casing SEW-110T
-
摘要: 在充分了解油田实际工况的基础上,开发了SEW-110T高抗挤套管,通过力学性能测试、拉伸至失效、静水压至失效及外压至失效等手段测试了SEW-110T套管的性能。结果表明,SEW-110T套管的母材及焊缝区组织在具有高强度的同时,具有较高的韧性和塑性,因此表现出良好的抗拉伸、抗内压、抗挤毁性能。Abstract: High collapse-resistance oil casing SEW-110T was designed and developed on the basis of sufficient understanding of the casing's operating conditions in oil field. The performances of SEW-110T were evaluated by tests of mechanical property,tensile strength,hydrostatic pressure and external pressure etc. The results show that the base metal and weld zone of SEW-110T have high strength as well as good toughness and ductility, and therefore SEW-110T shows good mechanical properties, tensile strength,and resistance to internal pressure and external pressure.
