Comprehensive Physical Properties and Exploration Potential of the Permian Igneous Rocks in the Southwestern Sichuan Basin

The Permian igneous rocks in the Sichuan Basin represent a major breakthrough, opening up new prospect for oil and gas exploration, reservoirs have become field of exploration. Gravity-magnetic-electric exploration is an effective means identifying helps reducing multiplicity prediction results. However, lithology quite different, theory evaluation techniques need urgently to be improved. In order deeply study response characteristics gravity-magnetic-electric physical properties their relationships with reservoir parameters, property testing was carried out on outcrop samples southwestern Sichuan. comprehensive different lithologies, including basalt, tuff, volcanic breccia, were analyzed studied. Based geological rocks, such as mineral composition, microstructure, properties, multi-parameter intersection relationship model resistivity, polarizability, density, magnetic susceptibility, parameters established, favorable rock identification identified. results this provide basis technical support non-seismic Basin.
