Igneous rocks are well-developed in Nanpu Sag, and the identification of igneous rocks is of important meaning to provide basis for sandstone reserve confirmation. Because of the complexity of anisotropy of igneous rocks, the identification of igneous rocks is a worldwide problem, and the imaging and prediction become bottleneck for oil and gas exploration in Nanpu Sag. Taking account of Igneous rocks features in NP1 Area,we adopt RTM technology for seismic imaging, stratal slice technology for crater identification, and energyphase compound attribute analysis technology for basalt identification based on comprehensive analysis of seismic geological and logging data. Obvious effectiveness is achieved in practical seismic exploration in NP1 Area through this method.
