本文用线弹性断裂力学理论推导出了在水力压裂情况下轴向对称裂纹钻孔的破裂压力表达式,并用岩盐试件进行了实验验证。
In this paper, the theory of linear elastic fracture mechanics is used to deduce the fracture pressure of axially symmetric cracked borehole in the case of hydraulic fracturing. The rock salt specimen is used to verify the experimental results.
