高分辨率地震约束相建模

以委内瑞拉F油田Z油藏作为研究实例，利用测井资料约束地震数据，建立纵高分辨的三维地球地震波阻抗模型，再用随机反演地震三维数据体和井资料约束随机相建模过程，大大降低了相模型的不确定性；相控建模产生一系列孔隙度及渗透率的实现，在网格粗化后进行了流线模拟，优选出忠实于生产动态资料的实现。经流线模拟与注水动态比较，相控建模－岩石物理参数建模－网格粗化－快速优选（流线模拟）一体化建模产生的岩石物理参数模型与地质，测井，地震，动静态资料比较吻合，图3参3（周丽清摘）。

Stochastic facies modeling constrained by high-resolution seismic data

Taking the Reservoir Z, F oil field, Venezuela as an example, this paper illustrates the application of logs data to constrain seismic data for producing a high-resolution acoustic impedance 3D model. The high-resolution 3D data from stochastic seismic post-pack amplitude inversion and logs data are then used to constrain facies modeling process, which reduces the uncertainty of models greatly. Realizations for porosity and permeability are obtained by modeling constrained by facies. The realization which honors the production performance is selected after the up-scaling and streamline simulation. Streamline simulation, using petrophysical parameters models, shows good agreement with water injection behavior.
