摘要
为分析油气工程中地层变形导致的套管失效问题,采用多孔介质流固耦合计算方法,将储层作为具有多孔介质属性的材料,计算了多孔介质流固耦合作用下的地层变形.通过组合应用parasoid建模方法和布尔操作,依据辽河油田公司锦州采油厂J25区块的地质数据,建立了三维有限元实例模型.计算结果表明,地层变形控制了套管破坏,具有多孔介质属性的地层其变形速度明显大于其它地层,流固耦合作用对地层位移具有明显影响.依据计算结果分析,得到通过储层变形可以预测套管破坏位置的结论,为工程中的套管防护提供了建议.
In order to analyze casing failure in petroleum engineering caused by strata deformation, this paper adopted the calculation method of fluid-solid interaction in porous media, treated the reservoir as pore media, and investigated strata deformation under fluid-solid interaction. According to the geological data in J25 block of Jinzhou oil production plant of Liaohe oil field company, a three dimensional finite element model was constructed as an application example through Parasolid modeling and Boolean operation. The calculating results show that strata deformation controls casing failure, speed of strata deformation in pore media is much larger than that of other strata, and strata fluid-solid interaction affects displacement. According to the calculating results, stratum deformation analysis can forecast the position of casing failure, which provides recommendations for engineering protection.
