| 摘 要： | 地应力与井眼稳定、井筒压力系统控制、井眼井斜及方位的控制和井身 结构的确定紧密相关。因此地应力场的研究是钻井工种设计的基础工作之一。目前国内外对地应力作用下的套管外载的研究非常重视，相继开展了室内模拟试验和有关理论的研究。文中主要用有限元数值分析法研究蠕变地层中地应力对套管外载的影响。

| Abstract: | In-situ stress have been closed associated with wellbore stabilization,wellbore pressure control system,wellbore deflection and wellbore orientation control and wellbore structure confirmation as well.So in-situ stress field is also one of base works about drilling engineering design.Now,there are lots of importance attached to external pressure of case under the in-situ stress all over the world.Many colleges and fields have gradually developed indoor simultion tests and relative theories research.This paper mainly studies the influence of in-situ stress on external pressure of the case in the creep stratum with finite element numerical method. |
