大庆油田葡南一断块油藏断层发育、构造复杂,应用地质建模技术可实现构造模型的三维可视化,通过分析断层在空间的延伸及相互切割关系,建立了断块区地质模型；利用三维可视化技术分析研究剩余油的分布状况，使得剩余油的分布范围和剩余量由过去的定性描述变为定量，更精确的指导断块剩余油挖潜工作。针对葡南一断块目前剩余油分布状况的不同类型，制定了注采系统调整、复合措施等4套剩余油挖潜方案，进行对比优化，调整后已初步见到效果。 该技术不仅有利于后期调整,而且为断块区提高储量动用程度打下了良好基础。

The faults of first-fault block reservoirs of Punan Area are well developed in Daqing Oilfield and the structures are complex.
Applying the Petrel 3D visible structure modeling technology, we have analyzed the space extension and interactive incising
relations of the fault, and have established the geological model of the Block. We apply the visible 3D technology to analyze
distribution of remaining oil, which makes the remaining oil distribution from qualoitative description to quantitative description in
order to guide the potential tapping of the remaining oil of fault block oil reservoir. The result is good after adjustment. In view of
different types of the remaining oil in the fault block, we have drawn up four regulation projects, including the regulation of injecting
and producing systems,complex measures and so on. We have completed the optimization and comparison. The adjusting result has
been seen. The technology not only is beneficial to later adjustment but also lays a good foundation for increasing reserves utilization
degree in the block.
