摘要
根据地质概念模型,应用随机模拟理论,采用多学科综合和多种数据集成的建模策略及随机地震反演—随机建模一体化技术,利用地震波阻抗数据体进行约束,建立了相模型及相控储层参数模型。在随机地震反演过程中,应用地质统计学理论,将测井垂向采样密度与地震横向采样密度耦合,建立了一个高分辨率的波阻抗模型,并以其约束建立了三维地质模型,降低了井间储层预测的不确定性。
A geo-modeling strategy was put forward on the basis of geological concept and stochastic simulation theories,incorporating multi-disciplinary knowledge and various data.Using the integrated seismic inversion and stochastic modeling technologies,the facies model and facies-controlled petrophysical model were developed on the basis of constraint of seismic impedance.In the stochastic inversion,the geo-statistics was utilized to couple the dense vertical sampling of the log data with the dense areal sampling of the seismic data to develop a highresolution impedance model and then built a 3D geological model constrained by seismic impedance.The uncertainties of inter-well reservoir prediction could greatly decrease.
