Abstract: The Yangxia and Kezilenuer reservoirs of Jurassic in Block?LX1of Tabei uplift in Tarim basin are of deep buried and few wells characteristics. Using seismic data structure characteristics, combined with drilled data and modeling structural analysis, to predict the favorable oil?gas?bearing zones in the Block?LX1. Results show that such zones have characteristics as follows: the small time window seismic data structure characteristic abnormal value is in relative big error; the large time window seismic data structure characteristic abnormal value is in obvious anomaly; the seismic waveform appears in non?return?to?zero and not smooth multi?peak, and the abnormal value profile shows the strong structural anomalies. Base on these features, the Block?LX1is divided into four levels in oil?gas?bearing property, and Level?I belongs to very favorable zone with an area of about6.28km2, distributing in northern Block?LX1; Level?II belongs to favorable zone with and area of about14.26km2, mainly distributing in southern Block?LX1. This paper suggests that where the abnormal value is big and located in structural high could be taken as targets for further rolling petroleum exploration in this area
