Abstract：The forward modeling technology is widely used in each link in seismic exploration chain;data acquisition,processing and interpretation.The basis of forward modeling technology is building the forward geologic model.The method presented by the paper is to take medium with same velocity and same density as an unit to build a closed structure out of its surrounding interface,and those closed units connecting each other to built a geologic model with the feature of closed structure.The model of a closed structure,compared with a model of a layered structure,the maximum advantage is that it can effectively describe any complicated un- derground geologic structrue.First ,the paper introduced the feature of layered model ,then described the topologic relation between 2-D and 3-D closed model and finally presented relevant mathematic processing method.
