利用探地雷达(GPR)资料，模拟犹他州中东部白垩系费伦砂岩河流三角洲杂岩，估算了河道砂岩储层内部的三维流体渗透率分布。利用沿相邻悬崖面上4个钻孔和1个伪孔剖面5 cm间距的流体渗透率测量，结合探地雷达数据的瞬时幅度和频率属性，预测远离测量垂直断面的流体渗透率，并圈定油藏模拟内部泥岩层的分布和几何形状。确定了井数据(流体渗透率和泥岩含量)和探地雷达属性之间具有统计学意义的关系。这些标定应用于整个探地雷达体积，以估计三维流体渗透率的变化和泥岩单元的横向发展，测量和预测的流体渗透率范围为0.1-290md。五个被认为不含泥岩层的单元中有一个…
A 3‐D fluid permeability distribution is estimated inside a channel sandstone reservoir analog in the Cretaceous Ferron Sandstone fluvio‐deltaic complex in east‐central Utah from ground‐penetrating radar (GPR) attributes. Fluid permeability measurements at 5 cm spacing along four boreholes and one pseudohole section at the adjacent cliff face are used together with instantaneous amplitude and frequency attributes of GPR data to predict fluid permeabilities away from the measured vertical transects and to delineate the distribution and geometry of mudstone layers inside the reservoir analog. Statistically significant relationships are determined between the well data (fluid permeability and mudstone content) and the GPR attributes. These calibrations are applied to the entire GPR volume to estimate the 3‐D fluid permeability variation and the lateral development of mudstone units.Measured and predicted fluid permeabilities range from 0.1 to 290 md. One of the five units considered contained no mudstone lay...
