水力压裂模拟的相场模型研究进展与展望
Research progress and prospects of phase-field models for hydraulic fracturing simulation
摘要
Abstract
Hydraulic fracturing simulation of reservoirs is a complex fluid-solid-damage coupling process.Owing to the intrinsic advantages of the phase-field meth-od 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 fractu-ring 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.关键词
