讨论了应用VoxelGeo的层拉平技术,利用地震反射数据体及前期解释成果,恢复奥陶系古地貌,通过浏览拉平后的地震数据体,寻找古水系的踪迹,进行古地貌、古水系研究。在此基础上结合钻井等资料进行塔河油田碳酸盐岩储层预测。

In this paper we reconstructed the ordovician palaeogeomorphology by using VoxelGeo′s horizon flattening technique on seismic reflection data and previous interpretation results. With the flattened seismic data volume, we studied the palaeogeomorphology and palaeodrainage pattern via scrutinizing the trace of palaeodrainage pattern. Finally, carbonate reservoirs were predicted in Tahe Oilfield with the above mentioned results and other information such as well data.
