摘要
按二维线弹性断裂力学理论，分别用解析法及有限元法分析了水力压裂过程中，原地应力、岩层性质和压裂液密度等因素对裂缝扩展的影响，提出了预测裂缝高度的方法和计算程序．
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.
