摘要
复杂小断块的勘探一直是东部老油区难点之一,针对苏北盆地复杂小断块构造的地表和地下特点,采用处理解释一体化研究思路,有针对性应用全三维处理方法,提高复杂小断块的成像效果。以苏北盆地高邮凹陷为例,构造解释中以精细断层解释为突破口,开展构造样式研究,以模式指导复杂的构造解剖,并应用三维空间综合层位标定、相干体、三维可视化、变速成图等全三维解释方法,提高复杂小断块的圈闭识别和描述精度,并在实际应用中取得较好的效果。
Exploration of complicated small fault blocks has always been a hard nut to crack in the mature oil regions in eastern China. In view of the complicated surface and subsurface characteristics of the small fault blocks in Subei basin, the idea of integrated seismic processing and interpretation is adopted and full 3D data processing method is applied to improve the imaging quality of complicated fault blocks. Taking Gaoyou sag in Subei basin as an example, detailed interpretation of faults, study of structural patterns and mode-guided analysis of complex structures are performed in structural interpretation. Full 3D data interpretation methods, such as 3D spatial horizon calibration, coherence volume, 3D visualization and variable velocity mapping, are used in the identification and description of the complicated small fault-block traps to improve precision. The desired results have been achieved in practical application.
