页岩油实验分析技术进展OA

Shale oil is an important strategic replacement resource for increasing reserves and production of oil and gas in China.Experimental analysis technique has laid a solid foundation for the effective exploration and develop-ment of shale oil.Aiming at the practical requirements of shale oil experimental analysis technology in Daqing Oil-field,a literature information tracking and research method is used to study the current status and progress of shale oil reservoir evaluation and experimental testing research from three aspects of reservoir properties,oil-bearing properties and mobility.The results show that the evaluation of shale oil reservoir properties includes pore quantita-tive characterization and accuracy determination of porosity,permeability and saturation,which are closely related to reservoir space distribution characteristics of shale mineral composition,pores and fractures.The evaluation of shale oil-bearing properties and mobility includes the comprehensive analysis of parameters such as shale oil satura-tion,viscosity and density,which are closely related to the distribution of micro-area oil and fluid mobility.Further development direction of shale oil reservoir evaluation is also discussed,including the emphasis on the combination of 2D-3D techniques in modern imaging analysis to achieve fine characterization of multi-scales pore structures,strengthening comprehensive characterization and dynamic evolution studies of shale reservoirs to comprehensively assess the pore structure,fluid occurrence state and dynamic variation of shale reservoirs,and paying attention to the integrated development of various experimental analysis techniques for shale oil oil-bearing properties and mo-bility to improve the accuracy and reliability of shale oil mobility evaluation.
