| Abstract: | It follows based on the geological analysis results of developing characteristics for karst fissure cave-typed carbonate reservoir, the seismic response characteristics of fissure cave-typed carbonate reservoir are studied by means of laboratory model ,at some time, the features of seismic wave field are also discussed. The results that provided by 3D seismic imaging processing and drilling data showing that characteristics of fracture and cave near the weathered crust are a weaker amplitude,a highly ratio of amplitude,poorly coherence as well as lower impedance and travel speed. However,the features of fracture and cave within the reservoir are a stronger amplitude, a highly ratio of amplitude, poorly coherence as well as lower impedance and travel speed etc.. At last, the relationships among the different seismic attribute characters and relevant techniques as well as karst reservoir are reviewed. |
