摘要
为解决套损井修复后水力压裂施工时重新出现套损,以及确定套损点到压裂层的距离界限,通过对水力压裂过程的数值模拟,建立了套损修复井的轴对称计算模型,得出了套损点到压裂层的距离界限与施工压力的关系。
Axisymmetric numerical model for original casing-eroded wells is established through hydraulic fracturing numerical simulation,and it can help to determine the relationship between distance limit from casing erosion point to fractured zone and fracturing pressure,so as to refrain from casing erosion recurrence in original casing eroded wells.
