摘要
A 3D finite element model for simulating hydraulic fracturing processes is proposed with an ABAQUS code. Fluid-solid coupling and viscoelastic reservoir properties are considered in the model. A typical hydraulic fracturing process is simulated with the model and the obtained bottomhole pressure evolution is consistent with the data measured from field. The model is validated. The effect of viscoelasticity on fracture containment is simulated with the model and discussed. The results show that the viscoelastic model predicts smaller fracture height than that predicted by the elastic model, and the fracture height decreases as the viscoelastic parameters of the reservoir decreases.
