摘　　要：针对页岩油勘探开发中储层含油性、储集性、可动性、可压性的地质评价需求,结合岩石物理实验技术,系统总结当前页岩油岩石物理实验技术现状及面临的挑战和发展方向。针对页岩油储层的特殊性,现有的特色实验技术主要包括基于扫描电镜矿物定量评价系统的岩性分析技术、以TRA(Tight Rock Analysis)为代表的多物理实验融合物性测试技术、二维核磁共振可动油评价技术、可压裂性分析技术等。在分析上述技术局限性的基础上,提出页岩油储层实验分析技术需同时进行室内分析与现场分析。室内分析能力需建立不同地区二维核磁共振可动流体评价图版并发展3D数字岩石物理技术;现场分析需打造车载岩心实验室,集成全直径高精度光学扫描、自然伽马能谱测试、二维核磁共振、漫反射红外光谱测试、高温热解等实验手段,为快速获取岩心岩性、有机碳含量、成熟度、总孔隙度、可动孔隙度、孔隙结构、含油性等参数提供方法。In view of the geological evaluation needs of oil content,reservoir property,movability and compressibility in shale oil exploration and development,combined with the development process of petrophysical experimental technology,the current status and challenges of shale oil petrology experiments are systematically summarized,and the next development direction is proposed.In view of the particularity of shale oil reservoirs,the existing characteristic experimental technologies in the industry mainly include lithology analysis technology based on QEMSCAN system,multi-physical experimental fusion property testing technology represented by TRA,two-dimensional nuclear magnetic resonance movable oil evaluation technology,and fracturing analysis technology.Based on the analysis of the above technical limitations,this paper proposes that the experimental analysis technology of shale oil reservoir be analyzed indoor and applied in the field at the same time.Indoor analysis capabilities require the establishment of two-dimensional NMR movable oil evaluation plates in different regions and the development of 3D digital petrophysical technology.The well site needs to build a vehicle-mounted core laboratory,integrating full-diameter high-precision optical scanning,natural gamma spectroscopy,two-dimensional nuclear magnetic resonance,diffuse reflection infrared spectroscopy,high-temperature pyrolysis and other experimental methods,to provide methods for obtaining core lithology,organic carbon content,maturity,total porosity,movable porosity,pore structure,oil content and other parameters.
