| 摘 要： | 首先根据岩石断裂力学理论证明了水力压裂裂缝具有与缝内压力分布无关的椭圆形自相似扩展特征，在此基础上，结合断裂力学与流体力学给出了水力压裂裂缝内压力分布的近似解析解。

| Abstract: | It is proved first that hydrofracture has a self-similar elliptic extending characteristic which is independent of the praseure distribution in fractures by the theory of fracture me-chanics in this paper.Based on this theory ,the approximative analytic solutions of pressure distribution in fractures have been put forward by fracture mechanics coupled with fluid mechanics. |

| Keywords: | hydrofracture fracture extending fracture geometry pressure distribution in fracture |
