高强度材料在超深井钻机井架底座中的应用

Application of the high tensile material to the substructure of the super-deep well's rig derrick

超深井钻机井架底座在结构形式、构件布局、主体材料的选取等方面均有较高要求,常规的井架、底座主体材料难以满足超深井钻机特定的载荷和工况要求。通过对超深井钻机井架底座的结构分析、高强度材料的性能分析与对比以及井架底座有限元强度分析,最终选择具有高强度、高冲击韧性和良好焊接性的低合金高强度结构钢Q420E作为超深井钻机井架底座主体材料,并总结出高强度材料对超深井钻机井架底座结构性能的影响以及高强度材料的应用原则。

There is a high requirement for the derrick substructure of the ultra-deep well in structural form,layout of component parts and main materials. The ordinary derrick and main materials for the substructure cannot meet the needs of the special loading and operating conditions of the super-deep well's drilling rig. Through structural analysis of the well's derrick substructure,performance analysis and comparison of the high tensile material and finite element analysis of the strength of the substructure,the low alloy steel labeled Q420E,which has a high tensile structure,high impact toughness and good weldability,has finally been chosen as the main material for the well's derrick substructure,summarizing the effect of the high tensile material on the structural performance of the well's derrick substructure and the principle for applying the material.
