Sedimentary System Characteristics of the Sinuosity Meandering River and Internal Architecture Analysis of Point Bar

As the framework of sandbody in the meandering river sedimentary system,point bar sandbody results in internal heterogeneity extremely serious because of its unique deposition.On the basis of the microfacies analysis of the high-sinuosity meandering river in Bohai Basin,the article anatomized the internal structure of point bar sandbody in detail,and summarized a set of research methods.For characteristics of point bar sandbody,it proposed measures to improving potential production of remaining oil by horizontal well technology.
