WIPO Patent Application WO/2017/031615
Kind Code:
A1
Abstract:
A method of constructing a ground subsidence prediction model of a two-cavity salt cavern reservoir, belonging to the technical field of underground spaces. The method comprises: obtaining information of a two-cavity salt cavern reservoir and according to the information establishing a 3D geological analysis model of the two-cavity salt cavern reservoir (101, 201); selecting key points of the 3D geological analysis model of the two-cavity salt cavern reservoir (202); performing rheological analysis on the key points of the 3D geological analysis model of the two-cavity salt cavern reservoir to obtain a rheological analysis result for the key points (102, 203); and according to the results of rheological analysis of the key points, constructing a ground subsidence prediction model of the two-cavity salt cavern reservoir (103, 204). The invention establishes a 3D geological analysis model of the two-cavity salt cavern reservoir, accurately reflects anisotropic properties of a salt layer in 3D space, performs rheological analysis on key points in the model, thus constructing a ground subsidence prediction model of a two-cavity salt cavern reservoir, and thereby accurately predicting ground subsidence of a two-cavity salt cavern reservoir.
