Abstract:
The application of wave impedance inversion data to oil/gas reservoir prediction would generally have multiple solutions,due to the effects of reservoir characteristics,such as the wave impedances of sandstones and mudstones in Pinghu reservoirs would often be similar,the thinly interbedded reservoirs in northern Hubei block are affected by coal seams,the reservoir water salinity in Shiwu fault depression in northeastern China is very low,and karsts and fractures are unevenly distributed in carbonates in northern Tarim basin.Considering these conditions,oil/gas reservoir prediction has been made by using crossplot of multiple logging parameters and wave impedence data.The multiple solutions caused by using wave impedance data only can then be avoided.According to various conditions,logging parameters with relatively high sensitivity should first be carefully selected,then make the crossplots of those logging parameters and wave impedence data.The crossplots must be calibrated against the known oil/gas distribution.The oil/gas reservoirs in a new well can finally be predicted by using the calibrated crossplot.Practical testing has proved the prediction is feasible.
Key words: multi-parameter, oil and gas prediction, cross-plot, effectivity, petroleum stratigraphic horizons
