摘要: 运用ANSYS软件,建立了埋地套管的三维有限元模型。通过室内实验,分析了埋地套管管中心应力与地面施加载荷之间的关系,以及不同载荷下套管长度方向上的应力分布规律,并与有限元模拟结果进行对比,验证了模型的可靠性。最后结合油田几种套管案例建立了三维有限元模型,分析了套管达到屈服强度后的地面施加载荷的临界值,研究结果可为管道与套管的安全防护提供一定的参考。

Abstract: Three⁃dimensional finite element model of buried casing is established using ANSYS software. Through laboratory tests, the relationship between the stress within the center of buried casing and the load on the ground, and the stress distribution in the direction of casing length under different loads is analyzed,respectively. Finally, a three⁃dimensional finite element model is established according to several casing cases in an oilfield. The magnitude of the load on the ground is obtained when the casing reaches the yield strength. The research results can provide a certain reference for the safety protection of pipelines and casing.
