Based on core test data obtained from simulation of formation pressure and temperature

and in combination with multi-wave logging data

the petrophysical parameters for seismic prediction of Jurassic reservoir and hydrocarbon detection in the central of Junggar basin are studied.It is believed that there are some limitations for prediction of lithology with seismic attribute alone

and hydrocarbon detection is infeasible with traditional seismic attributes.Difficulties for reservoir prediction and hydrocarbon detection with traditional compressional wave impedance technology are discussed.It is suggested that a combination of AVO and elastic wave inversion method be used to effectively improve reservoir prediction and hydrocarbon detection.The results of the study are of practical significance for seismic in prediction of reservoir and hydrocarbon diction in the central of Junggar basin.
