【 摘 要 】

In processing and interpreting the shallow sea single channel or 2D seismic data, it is found that there are Mistie problems when the sections intersect. The existence of Mistie caused great inconvenience to our interpretation work, fine stratigraphic interpretation and amplitude mapping is required to do Mistie correction, therefore, the closure of seismic data is an indispensable work in processing. Through the analysis of Mistie problem of a shallow seismic area, it is resulted from the inaccuracy of navigation position and the tide, and the coordinate correction technique and tidal correction technique are used to correct the position inaccuracy and tidal effects. The correction result shows that the Mistie problem has been greatly improved.
