Research progress on the architecture modeling methods of meandering river reservoirs

In recent years,with the quantitative development of geological researches,the architecture modeling of meandering river reservoirs has become a research hotspot.This paper summarizes the research progress on the architecture modeling methods of underground meandering river reservoir in the past 10 years,emphatically expounds the research progress on the modeling methods for the internal lateral accretion interbeds of the point bar sand bodies,and categorizes the existing modeling methods of lateral accretion interbeds into three categories,i.e.,the surface-based modeling method,grid random modeling method and equivalent characterization method,further analyzing the characteristics and problems of various modeling methods.It is pointed out that the current architecture modeling of meandering river reservoirs has some problems in the aspects of subsurface configuration patterns of well area and uncertainty characterization,and it proposes that the integration of multiple modeling methods and the development&application of efficient numerical simulators are the key development trends.
