摘　　要：正演模型的建立将地质模型和地震模型有机地结合起来,不仅能区分岩性,也能进行有效的烃类检测.通过对哈萨克斯坦国某油田白垩系储层分析,经过岩石物理建模、AVO正演、楔状模型正演和确定性反演等一系列步骤,准确地预测了油水界面和储层分布情况,进一步证实了地质分析结果,从而减少了地震反演的多解性.The foundation of forward modeling band together the geology modeling and seismic modeling organically, not only to distinguish the lithology, but also analysis hydrocarbon effectually.Through reservoir analysis for the Cretaceous formation of in certain oilfield in Kazakstan, the exact forecast has been made for the boundary of oil and water and the distributing condition of the reservoir based on the series of steps, such as geophysics modeling, AVO forward modeling, cuneal forward modeling and affirmatory inverse etc., and it is also proved that the conclusion of geology analysis is correct, so the diverse solution of seismic inverse can be redudced.

关 键 词：地震反演 岩石物理建模 AVO效应 储层预测 烃类检测
