| 摘 要： | 为了模拟沉积地层埋藏成岩过程中,压实作用下储层物性参数的连续变化特征,采用自行设计的成岩作用模拟实验系统,利用不同的现代沉积物样品,开展了砂岩机械压实作用模拟实验.实验表明:砂岩机械压实作用过程中孔隙度和渗透率随深度的变化具有分段性,即早期速变阶段和晚期缓变阶段.利用缓变阶段的数据分析发现,深度与孔隙度之间存在着良好的...

| Abstract: | In order to simulate the physical property change of sedimentary strata in the diagenetic process,a set of new equipment was designed and applied to simulate the mechanical compaction using different modern sediments.Results of the experiments show that the porosity and permeability are not regularly changing during compaction,and it can be divided into two sections,i.e.a sudden change section at early stage and a uniform change section at later stage.In the uniform change section,the porosity decreases wit... |
