Log data historical retrogression treatment method based on oil reservoir model

2014 
The invention relates to a log data historical retrogression treatment method based on an oil reservoir model. The log data historical retrogression treatment method comprises the following steps: 1) establishing the oil reservoir model; 2) establishing non-linear relations between seismic response parameters and rock parameters; 3) synthesizing a dynamic velocity of longitudinal wave, a dynamic velocity of transverse wave and dynamic density of the reservoir model; 4) respectively calculating the change rates of the velocity of longitudinal wave, the velocity of transverse wave and the density; 5) calculating an actual-measured velocity of longitudinal wave, an actual-measured velocity of transverse wave and actual-measured density, which are corresponding to a seismic data acquisition time point, by using the change rates of the velocity of longitudinal wave, the velocity of transverse wave and the density, obtained through actual measurement and calculation; and 6) conducting forward modeling by using the retrogressed velocity of longitudinal wave, the retrogressed velocity of transverse wave and the retrogressed density, and conducting consistency comparison and analysis on the synthetic record and the corrected seismic record to judge whether the retrogressed log data are correct or not. The change of the underground reservoir during the development process of the underground reservoir is responded objectively and really, and a good basis is established for accurately predicting the position of the underground reservoir and the change of the underground reservoir.
