基于地震反演约束的储层建模方法及应用
Application research of reservoir modeling method based on seismic inversion constraint
摘要
Abstract
3D modeling technology based on seismic inversion constraint is studied in order to improve reservoir prediction and characterization accuracy.The comparison of 3D wave impedance obtained by geostatistics inversion method with the conventional deterministic inversion results reveals that the wave impedance data by geostatistical inversion method is of higher vertical resolution and lateral prediction,and it can reflect the thickness of thin reservoir and the change of physical property.Accordingly,the physical models of P-wave impedance,lithology,porosity,permeability and saturation are established.The low impedance values represent the well developed layers and positions.Then,the lithological model and reservoir attribute model of the study area are established by using the stochastic simulation algorithm and by taking the P-wave impedance data body as the trend constraint.The practical drilling test proves that the results are in good agreement with the well point data,with good accuracy and reliability.This method can meet the needs of fine reservoir description and potential tapping of remaining oil.关键词
