摘要
储集层内的不同岩相的变化反映了不同沉积环境和沉积能量的变化 ,因而使得储集层在纵横向上呈现非均质性 ,储集层的物性参数在纵横向上亦呈现非均质性。根据砂泥岩储集层的非均质特性 ,提出了利用岩相的变化特征结合测井资料计算储集层渗透率的方法 ,以适应油田高含水后期调整井非均质水淹层精细解释的要求。
Changes of different lithofacies reflect the changes of different sedimentary environment and sedimentary energy in reservoir, which makes reservoir heterogeneous in longitudinal and transversal direction, hense also petrophysical parameters. A method is proposed in this paper for calculating reservoir permeability using log data and lithofacies to keep abreast of fine interpretation on watered out stratum of adjustment wells in the later period of high watered out fields on the basis of heterogeneous property of sand shale reservoir.
