摘要
Abstract
For the strong heterogeneity characteristics and buried comparatively deeper, as well as signal - to -noise ratio and resolution is relatively low, Seismic Reservoir Prediction of the lower Permian Maokouan strata fractured-cave reservoirs in southern Sichuan basin is very difficult. Based on forward modeling of two-dimensional geologic structure, this paper analyzes the resolution of two-dimensional seismic data to the single fractured-cave reservoirs by different offsets, and It also studies how the high density seismic data to reduce space aliasing and enhance the seismic lateral resolution in Seismic data processing. The seismic velocity inversion results of the theory model and actual data analyses further proved that the high density seismic data can effectively improve prediction accuracy of the fractured-cave reservoirs.关键词
