Abstract：It is showed from 3-D high-resolution and amplitude-preserved seismic data in Ordovician carbonate of Lunnan area,Tarim basin,that there exist a lot of desultory reflected energy forming"short event" in buried hill.According to seismicreflection theory and combining with the analysisand the study-for core and logging data,it is con-sidered that the reflected energy and "short event"in disordered level are a seismic response to carbonate reservoir in buried hill.The paper presenteda simple and convenient method that can quantitatively describe the disordered reflected energy,mainly used to predict the plan distribution rule offractured reservoir in carbonate.which is called forreservoir prediction by laterally regional amplitudedifference.The practice of application in Lunnanarea showed that the method has simple,convenient and practical characters and the feature ofprediction with high-precision,having prominentapplied effect in exploration of oil/gas reservoir inOrdovician fractured carbonate buried hill,Lunnanarea,and having a referential role in oil/gas exploration of carbonate in other platform and basin.
