Abstract: The seismic impedance inversion technique is one of the practical reservoirs prediction features,especially in those areas of the complex and heterogenetic reservoirs.The seis-mic impedance inversion technique can be used to get better results,and can not be replaced by other seismic techniques.The technique of the reservoir feature parameters inversion is based on the seismic impedance inversion,useful technique to depict the reservoir features.This technique is applied to the study on reservoir features at Mobei area in Junggar ba-sin with an effect as original expectation for the reservoir feature parameters.The prediction results have been valida ted by wells,and have been consonant with the region geo-logical sediment characters.The geological cognition and re-sults have been adopted by Xinjiang oil field for oil and gas exploration and wells locating.
