| 摘 要： | 川东北海相碳酸盐岩储层物性变化大,孔隙结构复杂,导致饱和度模型参数m、n值变化大,为饱和度计算参数合理选取带来难度.利用实验结果计算了m、n值,并对其影响因素进行了分析,认为m、n值与储层类型、储层物性等因素有关;随着储层孔隙度增高,m、n值逐渐增加,而裂缝的存在使m值明显降低、n值增大;根据m、n值变化对含水饱和度计...

| Abstract: | Large variations of reservoir physical properties and complex pore structures lead to the variations of m and n parameters of marine carbonate saturation model in Northeast Sichuan,so,it is difficult to select the parameters of calculating saturation.On the basis of core electricity experiments,calculated are cement index m and saturation index n parameters of the saturation model.And investigated are the effect factors on electrical parameters.The result shows that the values of electrical parameters are r... |
