提出了一种基于渗流理论的水力压裂耦合模型。通过与解析解和实验解的比较,验证了所提出方法的有效性.研究了地应力分布、天然裂缝面摩擦力和天然裂缝网络对水力裂缝扩展的影响。模拟结果表明,地壳应力比主要影响高频波的传播方向。当高频和神经纤维连接时,由神经纤维打开引起的诱导应力偏转新裂缝的扩展方向。纳米纤维表面的摩擦力是影响纳米纤维与纳米纤维相互作用的重要因素。
A coupled hydromechanical model based on peridynamics is proposed to simulate the hydraulic fracturing in a complex fracture network. The proposed method is validated by comparing the numerical results with the analytical and experimental solution. Then, the influence of the crustal stress distribution, the friction force acting on the natural fracture (NF) surface and the NF network on hydraulic fracture (HF) propagation are investigated. The simulation results reveal that the crustal stress ratio mainly affects the HF propagation direction. When HFs and NFs are connected, the induced stress caused by the opening of NFs deflects the propagation direction of new fractures. The friction force on NF surface is an important factor affecting the interaction between HFs and NFs.
