摘要: 储层的水力压裂模拟是一个复杂的流-固-损伤耦合过程,由于相场法在多物理场模拟方面具有天然的优势,因此,在水力压裂模拟领域被广泛应用。经过十余年的发展,出现了许多用于水力压裂模拟的相场模型,如基于线弹性断裂力学的脆性断裂相场模型、考虑峰后塑性阶段的延性断裂相场模型、考虑岩石黏弹性行为的相场模型,以及假设裂缝尖端存在内聚区的准脆性断裂相场模型等。这些模型涵盖了大部分的岩石断裂类型,包括脆性断裂、延性断裂、黏弹性断裂、准脆性断裂等。为了继续推动相场法在水力压裂模拟中的发展与进步,特别是在断裂类型判断、多物理场耦合、流体流动和岩石变形方程创新等方面的技术进步,对相场模型在水力压裂领域的进展进行了总结,并指明了相场模型在水力压裂模拟领域的发展方向。该研究可促进相场模型在水力压裂模拟中的推广应用,为突破现有模型的局限性提供技术思路。

Abstract: Hydraulic fracturing simulation of reservoirs is a complex fluid-solid-damage coupling process.Owing to the intrinsic advantages of the phase-field method in multiphysics simulation,it has been widely applied to hydraulic fracturing simulation.Over more than a decade of development,numerous phase-field models have been developed for hydraulic fracturing simulation,including brittle-fracture phase-field models based on linear elastic fracture mechanics,ductile-fracture phase-field models considering the post-peak plastic stage,phase-field models considering the viscoelastic behavior of rocks,and quasi-brittle-fracture phase-field models assuming the presence of a cohesive zone at the fracture tip.These models cover most types of rock fracture,including brittle fracture,ductile fracture,viscoelastic fracture,and quasi-brittle fracture.To further promote the development and advancement of the phase-field method in hydraulic fracturing simulation,especially technical progress in fracture-type identification,multiphysics coupling,and innovations in governing equations for fluid flow and rock deformation,this paper summarizes the progress of phase-field models in hydraulic fracturing and indicates future development directions for phase-field models in hydraulic fracturing simulation.This study can promote the wider application of phase-field models in hydraulic fracturing simulation and provide technical ideas for overcoming the limitations of existing models.

Key words: hydraulic fracturing, phase-field model, numerical simulation, fracture type, multiphysics coupling
