A Preliminary Research of the Establishment of Reservoir Geological Model of Fanfront Braided River-An Example of Haizou Outcrop Sandbodies in Fuxin Basin

摘要: 本文选择阜新盆地海洲矿野外露头砂体研究为例，对四个主砂体及一些辅助砂体进行了大比例尺实测及密集取样。根据储层建模的四项基本原则，以沉积序列、成岩作用与孔隙演化、物性特征及非均质性研究为基础，建立了６０ｍ、２０ｍ、１０ｍ、３ｍ、１ｍ（Ａ型及Ｂ型）一维储层地质模型；再结合结构单元分析、沉积模式、成岩模式和物性模式，建立了扇上、扇端、扇前辫状河二维储层地质模型。所建立的模型是岩性与物性的统一，是原型地质模型或概念模型。Abstract: This peper tubes the Haizhou outcrop sandally in Fuxin Basin as an example.Four main sandboies and some supplementary sandbodies are practically measured in a large scale and sampled densely.According to four basical principles of the establishment of reservoir geological model,based on the reserches of sedimentuny sequence.diagenesis and pete evolution.physical property andbeterogeneity, one-dimensional reservoir geological models of 60m .20m .10m.30m.1m (A-typeand B-type) grades are established.Combined with architeCtural-element analysis.sedimentary model.disgenesis model and Physical model, four two-dimensional reservoir geological models of fan, fanend and front-fan braided stream are established.The models established are of unified lithologies and physical Properties.Thus, they are prototype models or concept models.
