层内夹层 meaning in Chinese
intraformational bed
Examples
- The studies of in - layer heterogeneity are as follows : the text depicts the characteristics of heterogeneity by calculating the coefficient of variability , kmax / k and k . max / k . min of sand layers of different sedimentous microfacies ; divides interlayer into two types , and counts their numbers , thickness , frequency and density of a single sand layer according to the characteristics of lithology and logging , finally summarizes the characteristics of interlayer distributing ; sets up five in - layer heterogeneity models and points out that the primary models are model a and c . the studies of between - layer heterogeneity are as follows : the text depicts sand layers " growth and distributing conditions by calculating the lamination factor , sandstone density and overlap coefficient ; makes certain the lithology and thickness of interlayer by the method of contrasting the typical curves
层内非均质性研究，通过计算不同沉积微相砂体渗透率的变异系数、突进系数以及级差来说明主要储集微相的非均质特征；据岩性及电性特征，将层内夹层分为两类，统计单砂层段内夹层的个数、累积夹层厚度、夹层频率及夹层密度，并且根据夹层频率及密度平面分布图统计出每层的频率相对高值区和低值区，总结夹层分布特征；根据物性参数随深度的变化趋势建立了五种储层层内物性非均质模式，指出研究区内以a型和c型模式为主。 - In the core , more than 20 kinds of lithofacies was recognized and more than 6 type microfacies including channel , inter - channel , sheet - like sand , lake and salt lake was distinguished . 2 founding stratigraphy framework through base level analysis four scales cycle was distinguished from the core . very - short term base level cycle is equal to a sediment incident
储层物性较差，孔隙度多在11 - 13之间，渗透率多小于5毫达西，层内夹层较为发育，层内和层间渗透率差异明显，渗透率变异数多在0 . 7以上，孔隙喉道细小，以小于0 . 1um的喉道为主。
