| 摘 要： | 油田套损是石油工程中的一大技术难题，多年来困扰着各油田。大量的现场调查和理论分析表明，油田套损与油藏渗流场动态变化密切相关。无论是剪切套损、拉伸套损还是挤压套损，都是渗流引起应力场调整，最终导致套管受力损伤。基于油藏流固耦合理论，分析了油田渗流诱发套损的机制，建立了油藏渗流-应力耦合计算的数学模型，并介绍了利用流固耦合进行套损预测计算的算例，对于套损防控具有重要的理论指导意义。 |
| 关 键 词： | 套损 渗流 地应力 数值模拟 流固耦合 |

| Abstract: | Casing damage is a difficult technical problem and puzzle oil field for a long period. Large field investigation and theoretical studies show that casing damage is closely related to seepage field changes. Shear failure damage, tensile damage and extrusive damage are all induced by seepage. Based on fluid-solid coupling theory, mechanism of seepage induced casing damage were analyzed; a mathematical model to predict casing damage is established; finally and listed simulation cases are given. It is significant to guide the casing damage prevention and forecast. |
| Keywords: | casing damage seepage geostress numerical simulation fluid-solid coupling |
