摘要
Recently, the study of geometry and emplacement mechanisms of igneous sills by using 3D seismic reflection data has made great achievements,which has started a new ear of igneous tectonic analysis. Interpretation of 3D reflection seismic data offers a novel approach to the understanding of the fundamental aspects and hydrocarbon implications of basinal igneous tectonics. The research of igneous tectonics is one of the key fundamental problems of structural analysis in sedimentary basins, and is of broad practice prospecting in the petroleum exploration. A better understanding of the igneous rocks will improve the understanding of basinal structures and hydrocarbon traps related igneous rocks, and bring a number of new ideas of hydrocarbon exploration.
