Multiattribute Reservoir Prediction of Hei 49 Block in Daqingzi Oilfield, NE China
Reservoir plane features of Hei 49 block in Daqingzi Oilfield is analyzed with multiattribute analysis. Through the production of fine synthetic seismograms, the block is analyzed by non-linear multiattribute. The authors set up the relationship between the log information and and the multi-attribute, and this relationship will calculate the seismic properties of theogram demarcation and extrapolate well curve. The way is used to establish statistical relationships by nonlinear artificial neural network. Therefore, seismic attribute volume can be transformed into a variety of reservoir parameter data volume. The method to establish relations between seismic attributes and reservoir parameters overcome the problem of inversion's multiple solutions caused by the geological model and seismic wavelet, and it is a more realistic prediction for this block's reservoir prediction and description.
