Abstract:Reservoir description has been developed from description of single structured attitude of reservoir and prediction of reservoir parameters to building 3-D structural model of reservoir,reservoir model and geologic model of reservoir;from the research of single discipline to integrative research of mufti-discipline;from qualitative description to half-quantitative and quantitative predic- tion;from qualitative appreciation to 3-D reservoir attributes model-building.Laying emphasis on application of following seismic techniques:coherent cube,3-D visualization,seismic attributes analysis,velocity-changed mapping,well-logging data processing and interpretation,mufti-well-constrained inversion and geologic model-building of reservoir,the paper explained that these techniques can solve which kinds of practical geologic problems of oil-field and the trend in the future.
