储层微观非均质性及其在致密油运移与聚集中的研究进展

Reservoir micro-heterogeneity and its research progress in tight oil migration and accumulation

随着致密油研究进入开发阶段,以往宏观上的工作不能满足现生产与科研的需求。通过大量文献调研,从储层微观非均质性入手,总结致密油在此空间中运移与聚集过程中的机理与特点,然后总结了储层微观非均质性的研究手段,如:孔隙结构模型重建技术,流体特征可视化研究技术等。通过结合致密油成藏特征,分析其新兴技术对致密油运移与聚集的影响,同时也讨论了致密油运移与聚集在微观储层研究中所存在的问题。为进一步的成藏研究奠定了理论与技术基础。

It cannot meet the needs of current production and scientific research with the previous macro works,because the development of tight oil research.Based on a large number of literature surveys,this paper starts with the reservoir micro heterogeneity,summarizes the mechanism and characteristics of tight oil migration and accumulation in the micro space,and then summarizes the research methods of reservoir micro heterogeneity,such as:Pore structure model reconstruction technology,fluid feature visualization research technology,etc.By combining the characteristics of tight oil reservoir accumulation,the influence of its emerging technologies on tight oil migration and accumulation is analyzed,and the problems existing in the study of tight oil migration and accumulation in micro-reservoir are also discussed.It lays the theoretical and technical foundation for further research on accumulation.
