Abstract：As several oil-bearing structures were found out in Upper Triassic Xujiahe Formation in Sichuan basin, the reservoir prediction in Upper Triassic Xujiahe Formation on Shizhu synclinorium in the area of western Hubei and eastern Chongqing was implemented. At first the sedimentary characteristics and reservoir characteristics of Xujiahe Formation were analyzed and described, and then reservoir prediction was elaborated and implemented as below: (1)conducting stratum forward modeling and obtaining seismic response; (2)analyzing seismic facies, applying artificial neural networks to classify waveforms, then dividing seismic facies; (3)interpreting seismic facies, converting seismic facies in different intervals into sedimentary facies, at the same time applying wave impedance inversion technology, at last distribution and thickness of the reservoir were identified and the reservoir was proven by drilling, it is demonstrated that the reservoir prediction above is effective and applicable.
