双交联凝胶在油田调剖堵水中的应用研究进展
Recent advances in the application of dual-crosslinked hydrogels for profile control and water shutoff in oilfields
摘要
Abstract
Objective This review aims to clarify the influence of different crosslinked network structures on the properties of dual-crosslinked hydrogels and to provide a theoretical reference for the rational design of hydrogel formulations and the optimization of preparation processes in future studies.Method Starting from the energy dissipation mechanism,this paper systematically explains how dual-crosslinked hydrogels enhance tensile strength,compressive strength,and toughness.It also discusses the synergistic effects of dynamic reversible covalent bonds and noncovalent bonds in improving self-healing efficiency and stability.Result Dual-crosslinked hydrogels can enhance both mechanical strength and self-healing capability through multiple energy dissipation pathways and the reversible reconstruction of dynamic bonds.However,practical applications still face inherent trade-offs between injectability and mechanical performance,as well as between structural stability and self-healing efficiency.Conclusion Future research should further optimize the network structure and preparation process of dual-crosslinked hydrogels by taking reservoir conditions and field operation requirements into account,thereby promoting their application in oilfield profile control and water shutoff.关键词
