构造建模是储层地质建模的基础,精确的构造建模为后期建立准确的相建模和属性建模提供了有力保证,同时也为数值模拟打下了良好的基石。由于在复杂断块油气藏中,储层受多期次、多组合断层切割,使其在纵向上构造幅度大,横向上连续性低,从而使构造建模成为了复杂断块油气藏三维建模的难点。在临13断块油气藏建模中,采用分级断层、组合关系、综合模拟、质量检验的方法,得到符合地质构造特征的临13断块油气藏的三维地质模型。
Structural modeling is the foundation of reservoir geological modeling. Accurate structural modeling provides a powerful guarantee for establishing accurate phase modeling and attribute modeling in the later stage, and also provides a good foundation for numerical simulation. Because of the complex fault block reservoirs, the reservoir is cut by multi-period and multi-combination faults, so that the structure has a large amplitude in the vertical direction and a low continuity in the lateral direction, so that the structure modeling becomes a three-dimensional Mold difficulties. In the modeling of Lin13 fault block reservoir, a three-dimensional geological model of the Lin13 fault block reservoir that meets the geological structure features is obtained by means of hierarchical faults, combination relations, comprehensive simulation and quality inspection.
