摘　　要：静校正处理质量对地震后续处理是至关重要的。本文利用物理模拟的具有起伏地形的断层模型记录,对地形高程数据分别加5%、8%、10%的随机噪声。再基于单一变量法对共炮点数据进行高程静校正,最后对获得的时间叠加剖面叠加效果及模型位置等信息进行分析。总结出,地震资料处理时,高程测量误差在5%左右的范围内时不会影响在时间叠加剖面对地层和构造的准确识别等。这对野外的地震数据处理具有一定的指导意义。Static correction quality is essential for follow-up processing of seismic . In this paper, we use the physical model to simulate the fault of the terrain, and add 5%, 8%, 10% random noise to the terrain elevation data. Then, based on the single variable method, the static correction of the common shot data is carried out. Finally, the superposition effect and the position of the model are analyzed. It is concluded that when the seismic data is processed, the height measurement error will not affect the accurate identification of the strata and structure in the time stack section in the range of about 5%. It has certain guiding significance to the field seismic data processing.
