Abstract: Based on core analysis, the lithalogies, electrology charac-ters, and wave impedance characteristics of Igneous Rocks have been analyzed with geological, logging, seismic and many other information. The carrelativity between the lithologies, electrology characters and wave impedance, seismic attribute has been systematically investigated. To overcome the shortage of conven-tional wave impedance inversion, a set of multi一attributes 1i-thological inversion of Igneous Rocks based on neural network has been established. The lithologies of Igneous Rock in Zaoyuan oilfield have been predicted with the inversion method ,and the distribution of thickness and porosity were given.

Key words: Igneous Rock, lithalogies, electrology characters, seismic attribute, neural network, lithological inversion
