地质建模技术在路70岩性油藏中的应用

Application of Geologic Modeling Technology in Lu 70 Lithologic Reservoir

路70岩性油藏纵向含油层系多、岩相横向变化快、储层具有较强非均质性。综合运用地震、钻井、测井等基础资料,应用Petrel精细地质建模技术,建立了路70岩性油藏精细三维地质模型,重新落实构造和储层分布;通过对各小层储层物性分布特征的分析以及储量复核,认为该油藏物源来自东南和西南两个方向,指出该油藏大王庄边界断层的上升盘区域为下一步有利勘探潜力区,同时提出了设计井位建议;该项研究成果为路70岩性油藏的有效动用、开发方案编制提供可靠地质基础。

In Lu 70 lithologic Reservoir,there existed multi-layers in vertical direction,and rapid changes of lithologic property in lateral direction,and strong reservoir heterogeneity.Based on the results of seismic,drilling and logging data and comprehensive geologic analysis,fine geologic modeling technology was used to establish 3D fine geologic model for Lu 70 lithologic reservoir,its structures and reservoir distribution were re-determined.The distribution characteristics of reservoir physical properties of each sub-zone were analyzed and the reserves were rechecked.It is considered that the oil sources of the reservoir come from the southeast and northwest,and it is pointed out that the upthrow side of Dawangzhuang Fault Block is a beneficial area for next oil exploration,at the same time suggestions are put forward for well location design.It provides a reliable basis for developing a plan for its reservoir production and 3D geologic modeling,and it has wide application prospects of wide application of 3D geologic modeling oil exploration and development.
