Abstract: By a fandelta outcrop, a set of techniques and methods of detailed study of reservoir outcrop have been worked out,including detailed description, measuring and sampling on the outcrop, laboratory experiment,geostatistic analysis and prediction methods of various geologic parameters. In addition, main controlling factors and space distributions of reservoir heterogeneities in different scales of a fandelta have been systematically summarized. As a result, the prototype model and knowledge database of reservoir deposited in environment are established so as to be introduced into subsurfacial reservoir analogies for identifying,predicting and evaluating the uncertainty in modeling.

Key words: fandelta, prototype model, geologic knowledge database, geologic statistic
