摘　　要：A油田的油藏属于埋藏浅、高孔、高渗、稀油、边水非构造油藏。针对开发前期识别原始油水界面的难题,以A油田三维地震资料属性分析为手段,利用油层、水层在振幅能量上的明显差异性识别出的原始油水界面,与开发井验证结果基本吻合。该方法在A-80井区推广应用,得到了系统试井资料及开发井实际钻遇情况的证实,表明该方法比较可靠。Reservoirs in A oilfield are non-structural ones characterized by shallow-burial depth,high porosity,high permeability and with thin oil and edge water. So it's difficult to identify an original oil-water interface during early development. In this paper,an attribute analysis to 3D seismic data for A oilfield is carried out and the original interface can be identified through an obvious difference of amplitude between oil and water layers. This identified result is basically coincident with tested result in development well. This identification is applied to A-80 wellblock and has been proved to be reliable by systematic well test data and actual drilling.
