| 英文摘要 | Aiming at calculating gravity anomaly of 2-D complicated and heterogeneous geological body, we propose Irregular Gravity Modeling (IGM) approach based on Delaunay triangulation. As we know, the most fundamental cell is triangle in 2-D space. With Delaunay triangulation, we can divide a two-dimensional body, extending horizontally with arbitrary cross-section, into various triangular prisms with varying density in optimal way. After inversing the density of those nodes, we can figure out the density distribution. Using analytic equations derived, our approach is convenient and efficient in calculating. In comparison with traditional approach, the implementation of Delaunay triangulation helps us to use various triangles to approximate the geometry of geological body, and varying density is more close to the real density distribution when figuring out 2-D geological body with complicated geometry and heterogeneous density. Here, we implement our method in inversing a gravity profile measured in Qianmiqiao Oil Field, analyze the result, compare our method with the conventional, and make a discussion. |
