Abstract: The applied software for predicting the distribution of flow units was developed with VB programming language on the basis of SuperMap control objects of geographic information system(GIS).This software integrated the functions of data management,spatial analysis and diagram visibility of SuperMap objects.The multiple reservoir properties for this software,such as lithofacies,porosity,permeability and net thickness,were stored by vector data objects of SuperMap.An integrated analysis of multiple parameters can be efficiently performed using the overlap analysis mode of this software.The new developed software was successfully applied to Weizhou Oilfield.The results show that the software can improve the division efficiency of flow unit.This software will be easily adapted to other situations,while changing the division criteria or the number of data/parameters involved.

Key words: flow unit division, prediction software, geographic information system, overlap analysis mode, secondary development control object, reservoir evaluation
