Method for automatically modeling point dam reservoir based on meandering ring shape database

The present invention belongs to the technical field of oilfield development reservoir modeling, and specifically provides a method for automatically a point dam reservoir based on a meandering ring shape database. The method mainly comprises: firstly, constructing a meandering ring shape database; then, meshing a plane distribution range of a to-be-simulated river channel belt, and simulating plane distribution of a meandering ring under constraints of a mesh attribute and a specified rule; and finally, establishing a three-dimensional point dam model. The method provided by the present invention realizes automatic simulation of the point dam in the river channel belt, and improves precision and efficiency of reservoir characteristics, so as to serve for development and production of oilfields. 本发明属于油田开发储层建模技术领域，具体地讲是种基于曲流环形态数据库的点坝储层自动建模方法，主要包括：首先构建曲流环形态数据库；然后网格化待模拟河道带的平面分布范围，在网格属性和指定规则的约束下模拟曲流环平面分布；最后建立三维点坝模型。本发明的方法实现河道带内点坝的自动模拟，提高了储层表征精度和效率，以服务油田开发生产。
