摘　　要：近期龙岗62井长兴组及剑门102井须家河组须三段获得重大突破,证实长兴组生物礁储层及须家河组碎屑岩储层均具有较大的勘探潜力。通过对研究区资料特征进行分析对比,在攻关中采用了纵横波阻抗叠前同时反演、体曲率属性、瞬时振幅属性等针对性技术,准确地刻画了生物礁台缘发育相带,预测了碎屑岩裂缝发育和油气有利聚集区,为研究区下一步井位部署提供了准确的资料基础,并形成了一套有效的技术流程。New breakthrough has been made in Changxing Formation of Longgang 62 well and the third member of Xujiahe Formation of Jianmen 102 well recently, which indicates that reef reservoir of Changxing Formation and clastic reservoir of Xujiahe Formation have great exploration potential. Based on comparing and analyzing the dada in work area, PP-PS joint inversion, curvature attributes and instantaneous amplitude are used in the study. The platform-edge is described accurately; clastic rock fracture development and favorable hydrocarbon accumulation zones are forecasted. The study has brought about accurate data for further exploration, and a set of technical countermeasures are developed.

关 键 词：四川盆地 纵横波阻抗叠前同时反演 体曲率属性 瞬时振幅属性
