Seismic Characterization On Fracture-cave Body Of Ordovician Carbonates In Tazhong 45 Area

The matrix porosity of carbonate reservoir is low generally because of long years and deep bury。The carbonate exploration activity in the Tarim basin is particular and complicate。The dissolution emposieu and fracture belt is the key hydrocarbon pore volume。The study of emposieu,fracture and their system can effectively predict the developmental regular patten of reservoir and oil and gas。By the study of structure and reservoir in the 45 borefild of middle Tarim basin and the application of coherence technique and the analysis of comprehensive properties,the paper predict the developmental regular patten of emposieu and fracture in the 45borefeld of middle Tarim basin。Particularly ,the paper utilize the data of aeolotropic azimuth to analyze the developmental orientation and plane developmental regular patten of fracture in the 45 borefild of middle Tarim basin。By the application of AVO analysis and prestack inversion technique ,the paper study the hydrocarbon bearing probability in the 45 borefild of middle Tarim basin。Moreover,the study of paper is be used to the actual manufacture and get the better application effectiveness and economic results。...
