Prediction of Sand Reservoir with Multi-Wavelet Seismic Trace Decomposition and Reconstruction
摘要
Abstract
Daniudi Gasfield in Ordos Basin is typically a lithologic gas reservoir with tight and anisotropic characteristics. There is no obvious seismic response of sand body due to low resolution,small difference of acoustic impedance between sand and shale,and strong reflection events from coal. Therefore,it is very difficult to predict the reservoirs in the area. Using the multi-wavelet seismic trace decomposition and reconstruction,each post-stack seismic trace is decomposed into a set of Ricker wavelets of different dominant frequencies. A new seismic volume is then reconstructed with wavelets within a selected range of dominant frequencies that reflect the reservoirs and used to predict the reservoirs and gas-bearing property.关键词
