Salt rock can make borehole close in the effectofcreep, which often leads to stuck.
盐岩在应力作用下发生蠕变导致井眼闭合,常引起钻具卡钻事故。

A simple and efficient analytical method ofcreep recovery stress is provided. The effectofcreep recovery is demonstrated by a numerical example.
同时,对高温结构提出一种简便可行的蠕变恢复应力分析方法,并通过算例说明蠕变恢复的影响。

In this paper, the creep compliance of Hot-plate welded joint of PE80 pipe is measured, and the effectofcreep on the crack tip stress field in the weld is investigated.
