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.

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.Some problems occuring in hydraulic fracturing have been well explained, and some new theoretical bases have also been given to the hydraulic fracturing of oil and gas wells in this paper.
