Deep brine resource evaluation is a very difficult issue. On the one hand, deep brine’s geological and hydrogeological parameters are difficult to obtain, and on the other hand deep brine’s evaluation method is lack of standard. Traditional evaluation method of deep brine resources is volumetric method. But volumetric method is too simple to describe spatial form of brine reservoir, and it also can not solve the problem of deep brine parameters serious heterogeneity. Volumetric method is easy to cumulative error. This paper proposes an improved model of the volumetric method. At first, it uses Opengl API 3D rendering technology to create threedimensional model of brine reservoir. Then, it uses Kriging method to set grid on the brine reservoir 3D model and builds simulation unit on the brine reservoir 3D model. At last, it uses simulation methods to solve the problem of parameters serious heterogeneity and calculates the resources. This method inherits the traditional calculating ideas, and it can obtain more accurate calculation result. In order to apply this method, a software is develops. This paper evaluates one brine structure’s resources of Northeastern Sichuan Basin as an example. This method can more fully exploit the deep geological parameters, and its result is better than volumetric method. This method is an effective improvement of the volumetric method.
