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

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.
