复杂地质条件下精细构造建模的技术策略

A set of technical strategies for fine structure modeling in complex geologic environments

渤海海域新近系断层复杂 ,构造破碎 ,地层横向变化很大 ,在这种复杂地质条件下进行精细构造建模的难度很大。为此 ,以全三维可视化解释为主要工作思路 ,对已引进的各种相关软件系统进行了技术组合应用研究 ,形成了一套在复杂地质条件下进行精细构造建模的技术策略 ,并在秦皇岛 2 7/ 33和渤中 2 5 1构造应用中取得了良好效果 ,为后续的油藏地质建模提供了高精度的边界约束数据。

For the Neogene in Bohai Sea, there are complex geologic conditions due to complicated faults, great lateral changes in stratigraphy and crushing structures, in which it is difficult to conduct fine structure modeling. Therefore,all、3D visualization interpretation has been taken as the main guidance, a combined application research has been completed for various introduced softwares, and a set of technical strategies for fine structure modeling in complex geologic environments has been developed. Its applications to QHD27/33 and BZ25、1 structures have resulted in good effects and provided refined boundary constraints for the sequent geologic modeling of reservoir.
