摘要: 本文以二维弹性孔板理论为基础,应用线弹性断裂力学理论,对油气井水力压裂作了理论分析,并得出了计算岩石破裂压力的公式。室内试验和现场实例表明,这些公式的计算结果比目前石油工程中广泛采用的公式更接近实际施工的情况。

Abstract: On the basis of the theory of two-dimensional elastic plate with holes, the use of the theory of linear elastic fracture mechanics in the hydraulic fracturing of oil and gas wells is discussed in this paper. The formulas for computing fracturing pressure of rocks have been obtained. A series of tests and field practices showed that the results calculated by these formulas are more approximate to the practice than those computed by the formulas used in the present petroleum engineering.
