摘　　要：塔河油田岩溶储集体(洞穴、礁滩、孔洞、裂缝或裂隙等)的地震波场特征是弱反射背景之上的强弱不同的绕射波,因此,绕射波准确归位成像和振幅保持是研究岩溶储集体的基础。笔者从塔河油田地震资料高保真处理实践中,总结出了一套适应该区碳酸盐岩储层预测要求的以叠后高精度偏移算法和振幅保持处理为主的叠后高保真处理技术,取得显著的效果。Seismic wave field feature of Ordovician carbonate karst reservoir (cave,reef,hole,crack and cranny )in Tahe oil field is thedifference magnitude diffraction wave over weak reflection amplitude,so,the diffraction wave exact imaging and fidelity amplitude processing is the basic of carbonate karst reservoir study.The paper,by the real seismic data high fidelity processing with post-stack high precision migration arithmetic and true amplitude in Tahe oil filed , summed up a set of post-stack seismic data high fidelity amplitude processing technology to adapt the area Reservoir prediction.
