摘要
CO_2在原油中的扩散在油藏增产中起着重要的作用,其影响到采收率提高幅度和原油黏度的降低程度等。本文从直接法和间接法两个方面进行了CO_2在原油中扩散系数测定方法研究进展总结,重点阐述了间接方法测定扩散系数的模型差别及研究进展,指出了完善影响因素分析、丰富研究维度、完善不同尺度孔隙中扩散规律研究等将成为未来CO_2在原油中的扩散研究重点和热点。图10表1参47
Diffusion of CO_2 in oil phase plays an important in enhanced oil recovery,since its impact on the recovery improvement percentage and oil viscosity reduction percentage. The research progress on the CO_2 diffusion coefficient measurement methods including direct method and indirect method,were summarized. The difference of mathematic models and research progress of indirect method were pointed out in this paper. Based on the summary,it is pointed out that the improving the analysis of impact factors,enriching the research dimension,and improving the study of diffusion law in different scale pores will become the focus and hotspot of the future.
