摘　　要：针对部分油气藏钻采过程中的固态烷烃相关混合物受热相变、超压砂体瞬间泄压触发砂体液化流动和孔隙充填物降压气化引发骨架垮塌3个典型的相变岩石力学现象,系统分析了目前在理论认识、实验方法、数学表征方面的研究进展,同时探讨了3个相变岩石力学现象对应的工程应用场景,揭示了其力学规律及工程应用效果,在此基础上,讨论了油气藏相变岩石力学目前所面临的挑战、潜在的发展趋势与亟待探索的方法。研究表明:不同的油气藏相变岩石力学现象需要采用相应的、特殊的实验及数学方法开展研究,确定其独特的多场耦合力学响应机制,以有效指导资源开采控制、致灾程度评价、地层稳定分析等。为满足该学科的发展需要,未来需挖掘更多油气资源开采中的相变岩石力学问题,开发特定的新型实验设备,借助人工智能与数字孪生技术,实现岩石相态变化力学过程的实时仿真与动态可视化。Considering the three typical phase-change related rock mechanics phenomena during drilling and production in oil and gas reservoirs,which include phase change of solid alkane-related mixtures upon heating,sand liquefaction induced by sudden pressure release of the over-pressured sand body,and formation collapse due to gasification of pore fillings from pressure reduction,this study first systematically analyzes the progress of theoretical understanding,experimental methods,and mathematical representation,then discusses the engineering application scenarios corresponding to the three phenomena and reveals the mechanical principles and application effectiveness.Based on these research efforts,the study further discusses the significant challenges,potential developmental trends,and research approaches that require urgent exploration.The findings disclose that various phase-related rock mechanics phenomena require specific experimental and mathematical methods that can produce multi-field coupling mechanical mechanisms,which will eventually instruct the control on resource exploitation,evaluation on disaster level,and analysis of formation stability.To meet the development needs of the principle,future research efforts should focus on mining more phase-change related rock mechanics phenomena during oil and gas resources exploitation,developing novel experimental equipment,and using techniques of artificial intelligence and digital twins to implement real-time simulation and dynamic visualization of phase-change related rock mechanics.
