摘　　要：综合分析研究了非常规油气储集层孔隙结构、非常规油气赋存状态、充注机理、富集主控因素和高产成藏模式方面的新进展。非常规油气地质研究从纳米孔隙的观测发展到全孔径孔隙结构的定量表征和三维重构,从非常规油气赋存状态的宏观、静态特征描述发展到微观、动态演化研究,从启动压差驱动和优势通道运移发展到跳跃式阶梯充注和润湿性优势输导,从"源控论"发展到源控下的"优势源储组合+保存条件"的成藏论,从非常规油气的"富集"地质模式发展到"富集+高产"的成藏模式,展示了非常规油气地质理论的研究进展和未来的发展趋势。在此基础上指出了非常规油气地质理论、深层非常规油气富集条件和资源可采潜力、非常规油气地质研究对工程技术的渗透及非常规油气资源共采基础地质研究面临的问题与挑战。The progress in pore structure characterization, hydrocarbon occurrence state, mechanism ofoil and gas accumulation, main controlling factors and high production model of unconventional oil and gas is reviewed. The unconventional oil and gas geological research developed from observation of the nanopores to quantitative full scale and 3D pore structure characterization, from macroscopic occurrence state study to microscopic occurrence state evolution discussion, from differential pressure drive and preferential channel migration to staged accumulation and wettability preferential migration, from accumulation controlled by source to accumulation jointly controlled by source-reservoir assemblage and preservation conditions, from accumulation model to enrichment and high production model, revealing the research progresses and future trends of unconventional oil and gas geology. Challenges are presented in unconventional oil and gas geological theory, enrichment conditions and recoverable resources potential of deeply buried unconventional oil and gas, combination of unconventional oil and gas geological research and engineering technique, and basic geologic research for joint mining of different unconventional oil and gas resources.
