Abstract: The Haizhong region in northern Jiangsu Basin is characterized by oil-bearing igneous rock (sequences). However this region is geologically and seismically variable due to the existence of numerous faults and fractured structures, and thus may be problemable in the interpretation of the volcanic rocks and stratigraphy. The (present) paper deals with the seismic recognition of the igneous rocks in the light of high velocity and high resistivity of the igneous rocks by using STRATA well logging inversion technique, and prediction of thickness and porosity of the igneous rocks by using EMERGE inversion technique.
