套管损坏是制约油气生产的瓶颈问题,而套管外挤载荷设计合理与否对套管寿命具有决定性的作用。
Casing damage is the bottleneck problem for oil and gas production. Reasonable design of collapse load is vital to the life of casing.
这一结论说明:在均匀水平地应力条件下,地层各向异性对套管受力有着较为明显的影响,在设计套管外挤载荷时,应该给予充分考虑;
So it is obvious that the formation orthotropy has great effect on the casing stress, which should be considered in casing design process.
