Abstract: Taking the reservoir geological modeling and reservoir quantitative evaluation modeling of Ng group in Miaobei,Jidong Oilfield as an example,directing against the complex block-fault area of fluvial deposition,to quantitatively study lithology, physical property and oil of reservoir,has been expounded,according to the technical clue of model constraining,drilling control and seismic extrapolate,using geostatistics technology and the information combination of geology,logging and testing,based upon 3-D logging-constrained inversion.In the meantime,by the effective superposition of structure,oil reservoir and oil-gas-water properties in 3-D space,the reservoir position and properties are described accurately and the 3-D video-model has been built up,which can quantitatively reflect the properties of oil and gas field.Through examination of practice,the precision of modeling has been largely raised.Thus,the credible geological basis has been provided for high-speed and high-effective oilfield development and for utilization of geological reserves.And the geological model has been also provided for numerical reservoir simulation to formulate the development plan and play an important role in the reservoir prediction.
