曲流河储层在我国各大油田占有很大比例,高含水期的剩余油被复杂的储层内部构型所遮挡,难以应用常规油藏描述方法进行挖潜。为此,从储层构型的起源开始,分析建立储层构型定性及定量构型模式的研究方法,包括露头和现代沉积、探地雷达、高分辨率地震以及经验公式,并对各种方法和技术的优缺点进行简评。结合曲流河地下储层构型研究的实践,分3个层次(河道、点坝、点坝内部增生体)总结归纳国内外学者在曲流河地下储层构型研究中应用的方法和取得的效果。研究认为,曲流河储层构型模式研究发展迅速,但缺少内部构型(如点坝内部侧积层)的定量模式;地下储层构型研究已形成了一定的技术路线,但是构型模式和井资料有效拟合难度大,而且建立点坝内部侧积层的建模方法也尚不成熟。针对目前的研究现状和存在的问题,指出了曲流河储层构型表征的发展趋势,这对于我国高含水期油气田的开发效率具有十分重要的实际意义,对丰富储层地质学也具有重要的理论意义。

Meandering reservoir takes a great proportion in large oilfields in China. Remaining oil in high water-cut stage is occluded by complicated reservoir architecture, and it is hard to trap by normal reservoir description method. Then, from the origin of reservoir architecture, the methods of qualitative and quantitative models are analyze, which include outcrop, modern deposition, ground penetrating radar, high resolution seismic and empirical formula, and the pros and cons of various ways are briefly evaluated. Combined with the practice of fluvial underground reservoir architecture, from three administrative levels (channel, point bar, adenoid in point bar), the applied method which scholars do research in underground reservoir architecture with and the results obtained are summarized, and the newest research development is analyzed. Studies indicate that the pattern of meandering reservoir architecture develop quickly, but there is short of internal architecture pattern; technical route has formed for the study of underground reservoir architecture, but it is difficult to well fit in architecture pattern and data, and modeling method of lateral accretion in point bar is not perfect yet. With aim at the current research situation and existing problems, the development tendency of fluvial reservoir architecture characterization is point out. It has important practical meaning of development efficiency in high water-cut stage and theoretical meaning of enriching reservoir geology.
