【摘要】 储层三维地质模型可以定量地表征储层的空间几何形态及物性特征,是反映地质特征三维空间变化与分布的数字化模型。采用地质条件约束下的随机建模方法建立杏树岗油田X4区西部三维地质模型。综合利用地质、地震和测井资料建立构造模型;用地质研究的沉积相图采用确定性建模的方法建立储层微相模型;按相控建模的思路,优选球型变差函数模型,以序贯高斯模拟方法对研究区储层参数进行模拟,建立储层参数模型。验证结果表明,杏树岗油田X4区西部三维地质模型与实际地质情况符合较好,为油田开发调整、后期开发方案编制、挖潜剩余油提供了地质依据。更多还原

【Abstract】 The geometry and physical properties of the reservoir could be quantificationally characterized by the 3D geological model,which was a digital model reflecting the 3D space change and distribution of stratum.The 3D geological model of the western X4 block in Xingshugang oilfield was established by adopting the stochastic modeling method controlled by geological conditions.The structure model was established based on geological,seismic,and logging data.On the basis of the geological sedimentary facies graph,the reservoir microfacies model was established by means of determinate modeling method.In accordance with the thought of facies control modeling,the optimal ball type variation function model was selected,the reservoir parameters were simulated by means of sequential Gaussian simulation method,finally reservoir parameters model was established.The proof results of the 3D geological model were accorded with the actual geological conditions,which could provide important geological references for oilfield development adjustment,production arrangement for later period,and development of tapping the latent power of remaining oil.更多还原
