Abstract：As an integrated seismic data processing and interpretation system,GeoEast has become a mainstream platform of clastic rock study in Tarim Oilfield after continuous improvements and applications for years.In the production and scientific researches,a series of effective approaches are selected,which can solve complex geological problems in the hydrocarbon exploration and development.Recently,we have worked on a 3D seismic survey in the Sangtamu Area,Tarim Basin,with a few approaches provided by GeaEast.For data processing,the well-controlled and amplitude-preserving prestack depth migration is carried out.For the data interpretation,we complete the whole interpretation process and achieve obvious results.Both the resolution and the signal-to-noise ratio are greatly improved,clastic rock characteristics and deep targets are clear,which meet the needs for structure interpretation and reservoir prediction.Based on our study,11 independent fault blocks are identified,and four wells deployed that all achieved high oil yield.Our study provides a good basis for the future subsequent rolling development in this area.
