塔里木盆地古城低凸起三维地震工区内的奥陶系碳酸盐岩埋藏深，非均质性强，且无钻井资料。重点对奥陶系鹰山组三段—四段白云岩的串珠状地震反射体进行地质诠释。采用均方根振幅属性预测了储层平面分布规律，应用缝洞雕刻技术预测了裂缝和串珠体发育区，运用相干、曲率属性预测了断裂、裂缝的分布，联合应用频率衰减梯度、低频能量、平均频率和吸收系数等手段进行了油气检测。通过对多种信息的综合分析，评价优选出有利勘探目标。基于上述工作部署的A井，在鹰山组三段灰质白云岩储层中获天然气勘探重大突破，证实了地震综合预测方法的有效性。

A geological in terpretation is done to the beads-shaped seismic reflectors shown in deep-buried Ordovician Yingshan-3 to -4 carbonate reservoirs with anisotropiy, which are selected in a 3-D seismic survey target area in Gucheng Low Uplift. A series of seismic interpretation technology are used to predicting the rule of reservoir distribution in plane, the fault and fracture distribution zones, and the beads-shaped reflector zones, as well as detecting hydrocarbon. Based on these integrative predictions, some favorable drilling targets in the reservoirs are evaluated and elected in this seismic target area. The fact that commercial gas flow was obtained from the Well-A that was arranged to drill into the Yingshan-3 dolostone reservoir has proved effectiveness of this integrative seismic predictions.
