摘　　要：高邮凹陷永安南地区戴南组主要发育三角洲前缘-前三角洲沉积,钻井揭示砂体在该区逐渐尖灭,具备岩性圈闭发育的地质背景。在地质评价基础上,综合地震属性分析、谱分解、波阻抗反演等多种地球物理手段,建立了岩性圈闭识别技术,并在永安南地区进行了应用,识别出了多个有利岩性圈闭,实钻取得突破性成果,证明了研究成果的可靠性。The sedimentary subfacies of E2d are delta-front and prodelta in southern Yong′an area of Gaoyou Sag.The drilling data reveal that the sands in this area became gradually pinch-out which has the geologic background of lithologic trap development.Based on the geological evaluation,the lithological trap identification technology was established by integration of the seismic attribute research,spectral resolution,wave impedance inversion.In southern Yong′an area,several favorable traps were identified by adopting the technology.The practical drilling practice has proved the reliability of the research results.
