摘　　要：塔河南探区三叠系中油组储层孔隙度高,渗透性好,但非均质性强,横向变化剧烈。针对这些特点,提出了三叠系中油组储层预测方法——频谱成像技术、测井约束地震反演技术和地震衰减梯度属性技术。利用上述方法技术对塔河南探区中油组储层进行了预测、分析和评价,刻画了砂体的分布特征,描述了有效砂体的含油气性,预测结果与钻井结果相吻合。The middle Triassic reservoir in south Tahe area is character- ized by high porosity and good permeability,but with strong ani- sotropy and considerable lateral changes.Aiming at the character- istics,we proposed the reservoir prediction methods for this area, including spectrum decomposition,well constrained seismic imped- ance inversion,and seismic attenuation gradient attribute technolo- gy.The abovementioned methods have been applied to predict,an- alyze,and evaluate the middle Triassic reservoirs in south Tahe ex- ploration area,successfully predicted the distribution of the sand and the oil-gas bearing capability,which coincide with the drilling results.
