Seismic attribute continuous mapping method across three-dimensional seismic work area

The invention discloses a seismic attribute continuous mapping method across a three-dimensional seismic work area. The method comprises the steps of 1, carrying out the removal of a boundary abnormalvalue generated by a seismic data boundary effect through combining with the plane features of an attribute horizon selected for the observation of a geological task; 2, normalizing the value domainof the attribute horizon of each three-dimensional seismic work area to unify the range of the value domain; 3, observing a region in which abnormal values of each attribute horizon are concentrated,and calculating the horizon value domain again to enable the abnormal value ranges to be approximately the same; and 4, splicing the adjusted horizon together. According to the method, the display characteristics of the three-dimensional seismic data and the same seismic attribute in different periods and different regions can be rapidly and efficiently adjusted, and the problems that multi-work-area region display characte
