Fine reservoir prediction method of oilfield development phase

The invention relates to a fine reservoir prediction method of an oilfield development phase. The fine reservoir prediction method comprises the steps of basic data collection, quality control and treatment: carrying out correction on problematic well log by adopting a rock physics method for the single well curve problem and the multi-well consistency problem; utilizing a rock physics analysis method to obtain well log parameters having discrimination on lithologic character, physical property or oil-gas possibility of reservoir, and determining target parameters of reservoir inversion; carrying out fine well-seism calibration to obtain an accurate time-depth relationship; adopting a routine wave impedance inversion method to obtain wave impedance data volumes as external attribute input of multiattribute inversion; for the characteristics of a multiattribute inversion method, filtering high and low frequency information of the well log by adopting a band-pass filtering means, namely, carrying out frequency matching of well-seism data; and taking the obtained wave inversion data volumes as the external attribute input and adopting the multiattribute inversion method to obtain a final inversion result. According to the fine reservoir prediction method of an oilfield development phase, the prediction precision can be effectively improved; the applicable range is wider, and the requirement of the oilfield development phase for reservoir prediction precision can be met.
