| 摘 要： | 储层物性参数在空间的展布，一直是储层非均质性研究的难点，利用分形和蒙特卡洛方法，在精细的沉积微相及小层对比研究基础之上，预测了井间的岩石相分布，并根据取心井资料，建立了各种岩石相的渗透率相控模型，从而预测出井间渗透率的分布。该方法以地质特征为基础，将地质资料与数学方法相结合，充分体现了渗透率在井间既具有连续性，同时变化又非常剧烈的特点，为储层物性空间预测提供了新的思路。

| Abstract: | The spatial distribution of the physical parameters in the reservoir has for a long time been a difficulty in the research into the reservoir heterogeneity. Both the fractal and Monto Carlo methods and the correlation between the fine sedimentary micro-facies and the sublayers are used to forecast the lithofacies distribution between wells. In addition, the core data are employed to establish the lithofacies-controlled models on the permeabilities for various kinds of lithofacies. Therefore, the permeabilities between wells can be forecasted. This method established on the geological features, combines the geological data with the mathematical methods, so as to fully reflect the continuity of the permeabilities between wells and the very violent changes in the permeabilities. In this sense, this method may serve as a new perspective for the spatial forecast of the physical parameters between wells. |
