Finite Element Simulation Analysis of Performance of Casing Premium Connection

摘要: 利用全尺寸實物試驗和有限元仿真方法，研究Ф244.48 mm×11.99 mm規(guī)格HSM-2特殊螺紋P110套管的接頭性能。結(jié)果顯示：有限元計算時，在ISO 13679∶2002標(biāo)準(zhǔn)CAL IV A系試驗所有加載點下，HSM-2特殊螺紋接頭主密封面均保持較大接觸壓力和密封長度，密封指數(shù)較高；實物試驗及有限元計算結(jié)果均證明了該接頭具有可靠的密封性能和連接強度；有限元計算扭矩與實物試驗扭矩能較好地吻合。

Abstract: The performance of the HSM-2 premium connection of the Ф244.48 mm×11.99 mm P110 casing is studied by means of the full-scale test and the FEA simulation method.The results reveal that the FEM calculation shows that the main sealing surface maintains a high contact pressure and a large sealing length as well as high sealing index under all the loading points of ISO 13679:2002 CAL IV Series A test.And the results of both the FEM calculation and the full-scale test result demonstrate that the said premiumconnection has reliable sealing performance and connection strength, and that the torque from the FEM calculation is almost identical with that from the test.
