| 中文摘要: |
| 油井套管的最小成本设计是工程中关心的问题，本文提出了Fibonacci搜索法与相对差商法相结合的套管截面尺寸参数和扶正器布局问题的混合整数-离散变量优化方法，解决了多工况、多约束下套管结构的优化问题，已应用于工程实际。 |
| 英文摘要: |
| The minimum cost design of casing structures of oil wells is an attractive problem in practical engineering. In this paper, the Fibonacci searching method is used with the relative difference quotient algorithm to give a mixed integer\|discrete method for solving sizing and layout optimization of casing structures and their supports. The proposed method is quite convenient and satisfactory when used to solve structural optimization of casing structures in multiple load cases and constraints and has been applied to practical problems. |
