Aiming at the issue of oil extraction data analysis and data display, this paper introduces an effective contour map rendering method considering constrained factors of the distribution of oil reservoir and geological conditions. The constraints such as faults, ridges, scarps and island areas are first classified into two categories of geometries, namely, polylines and polygons. Then, a Triangulated Irregular Network (TIN) is constructed based on the geo-locations of oil wells and further refined with local constraints of polylines and polygons. Finally, the intersections of line segments between a specified equivalent surface and the triangles in TIN are calculated and the contours are thus formed by connecting these intersection line segments. The approach is well demonstrated with the oil extraction data of Xinjiang oil field in China. 展开更多
