【Abstract】 Based on two-dimensional linear elastic fracture mechanics, the effects of variedin-situ stresses, different material properties and gravity of fracturing fluid on the crack propagating during hydraulic fracturing are studied,using analytic method and finite element method. A simple effective method to predict crack height quantitatively is presented and a finite element simulator is coded.更多还原
