摘　　要：塔河油田碳酸盐岩油藏油水关系复杂,储层主要受断裂控制,地震断裂检测是储层预测的首要任务。目前,塔河油田主体区已被高精度三维地震全覆盖,因此断裂、裂缝的检测和描述方法技术需要进一步优化。基于前期的断裂检测手段,综合应用精细相干、蚂蚁体追踪等多种技术,将断裂刻画得更为精细,其结果与开发井已揭示的油藏资料相符,证实了塔河油田奥陶系碳酸盐岩油藏为断控油藏,断裂是其主要的油气运移通道,具有明显的控储、控藏作用。The oil-water relation of carbonate reservoir in Tahe Oilfield was complicated,the reservoir was mainly controlled by the fault,seismic fault detection was the most important task for reservoir prediction.The 3Dseismic data were highly precision and fully covered in main region of Tahe Oilfield,the technology of fault,fracture detection and description method needed to be further optimized based on high quality 3Dseismic data.Based on the seismic fault detection at the initial stage,the fine coherent technology and ant tracking technology were integrally used,thus the,the fault characterization is more refined.The results are consistent with the reservoir data from the development well,it demonstrates that Ordovician carbonate reservoir is the fault-controlled one,the fault is the main hydrocarbon migration channel,it is used for reservoir controlling.
