| 摘 要： | 通过有限元模拟,计算分析了水泥环对套管的抗内压强度影响。得出有水泥环保护下,磨损套管的剩余抗内压强度变化规律。同时,对水泥环缺失条件下进行有限元计算。分析水泥环缺失一定角度时对套管抗内压强度的影响,得出水泥环在缺失不同角度时套管剩余抗内压强度的变化规律。通过分析发现水泥环缺失一定角度产生应力的集中,套管抗内压强度会比无水泥环保护时更低,若此时套管同时发生磨损,对套管强度和井控安全影响巨大。 |

| Abstract: | This thesis calculation and analysis the influence of cement loop on casing internal pressure strength by means of finite element simulation, got the relevant changes law of casing internal pressure strength after wear under under the protection of cement loop. .Through finite element calculation under the condition of cement loop lose, got the relevant changes law of casing internal pressure strength when the cement loop had a lack of a certain angle. Through analysis got that casing internal pressure strength of cement loop is lower than no protection of cement loop. |
| Keywords: | Cement Loop Deletion Internal Pressure Casing Wear Finite Element Analysis |
