摘　　要：上奥陶统良里塔格组礁滩体储层是塔里木盆地塔中地区主要储集层,为一套碳酸盐岩台地-陆棚边缘礁滩复合体沉积,埋藏深,非均质性强,储层类型多样,有效预测该类储层难度大。针对上述特点,设计了四个礁滩体储层模型,采用正演模拟方法,研究不同情况下礁滩体储层地震响应特征,并与已钻井实际资料对比,吻合较好,由此得出了关于礁滩体储层地震响应特征一些有意义的结论和认识,以便指导本区礁滩体储层预测,有效地减少储层预测结果的多解性。Upper Ordovician reef shoal reservoirs are main reservoirs in Tazhong area of Tarim Basin and reefbank complex deposition and deeply buried and good lateral anisotropy and reservoirs of various types.It is diffcult to predict reef shoal reservoirs.According to characteristics,in the paper four reef shoal reservoirs models are designed and forward modeling is adopted,then studies geophysical characteristics of reef shoal reservoirs,whose result is the same as the real well data,therefore,some significant conclusions are made.The conclusions provide guidance for predicting reef shoal reservoirs and the multiplicity of reservoirs prediction is reduced.
