In this study, the special well-seismic relation has been established on the basis of comprehensive analysis of newly acquired and processed 3D seismic data in a block of the North Yellow Sea Basin, and drilling and logging data of wells. Seismic facies analysis, pre-stack simultaneous inversion and multi-attribute analysis were used to identify and predict the geometry and spatial distribution of the igneous rocks. Seismic response of igneous rock was characterized. The results show that there exist a series of large buried-hill-type igneous rocks in the east, a typical piercing igneous rock mass in the northwest, and some small scattered intrusive stock or dyke in other areas of the studied area.
