摘　　要：在草湖凹陷东河砂岩尖灭线实际解释中,可能因地震资料的假象或陷阱而造成解释或预测结果的错误。针对地下东河砂岩复杂的尖灭地质现象,通过模拟东河砂岩厚度变化所造成的地震响应特征,并结合常规解释的成果,开展了东河砂岩地质建模与正演。建立了多个超覆尖灭的地质模型,进行正演模拟,精确预测尖灭点的位置,引导正确的解释方向。In fact,it's possible to result in the mistakes for the false or trap of seismic dada. Aiming at the complex pinch-out phenomenon of underground Donghe sandstone, through simulating seismic response character affected by the thicken of Donghe sandstone layer,combined with the common explanation, we build multi-pinch-out geological model,predict exactly the location of pinch-out point, and guide correct direction of seismic explanation.
