摘　　要：从目前裂缝性储层表征及建模研究现状入手,结合自身实践,详细介绍了裂缝性储层表征及建模研究中的各种方法,分析了每种方法的优缺点。裂缝表征中主要使用的方法包括:野外露头分析法、岩心分析法、测井分析法、地震预测分析法、动态响应分析法、岩石力学分析法。裂缝建模中主要使用离散裂缝网格模型和等效连续模型两种方法。其中,重点介绍了分形理论在野外火山岩露头裂缝分析中的应用、数字岩心技术在微观裂缝表征中的应用、各种最新的地球物理及岩石力学表征和预测裂缝的方法、动态裂缝在裂缝性油藏开发的作用、近年来国外学者所倡导的裂缝地层学理论、非常规储层中的裂缝表征,以及上述两种裂缝地质建模方法。在此基础上,讨论了裂缝性储层表征及建模中存在的问题,最终指出了该项研究未来发展的趋势。This paper introduces several main methods of fractured reservoir characterization and modeling, and summarizes theiressential advantages and disadvantages. The main methods for fracture characterization include field study, core and well logging,seismic prediction, dynamic response analysis, mechanical analysis, and rock mechanical analysis. And fracture modeling is conductedmainly with by DFN（discrete fracture network） and equivalent continuum modeling. This paper reviews the application of fractal theoryto outcrop fracture analysis of volcanic rocks, the application of digital core technique to micro fracture characterization, several mostrecent geophysical and mechanical fracture characterization and prediction methods, the impact of dynamic fracture on reservoirdevelopment, fracture stratigraphy theory proposed abroad lately, fracture characterization in unconventional reservoir, and finally theabove two fractured reservoir modeling methods. On the basis of all above, challenges for fracture characterization and modeling andfuture research in this field are pointed out.
