fluvial channel meaning in English
河道
Examples
- Numerical simulation study on three - dimensional velocity field of fluvial channel current
河道水流三维流速场的数值模拟研究 - In addition to , we summed the results of fields outcrop and fluvial engineering , established the geological thesaurus . ration the different type of fluvial channels shape parameters . then matched the logging interpretation model of shaliness . porosity unit , permeate ratio and hydrocarbon saturation originality , because using the measure of multianalysis and network . the precision is higher than the result of onventionality , so laid the fundation of knowing the characterof reservoir
此外，总结了国内外野外露头及河流工程的研究成果，建立了研究区的地质知识库，初步量化了不同类型河道的形态参数。还建立了不同类型河道的泥质含量、孔隙度、渗透率、原始含油饱和度的测井解释模型，由于引入了多元拟合及人工智能神经网络等手段，其计算精度高于常规解释结果，为精细分析储层内部性质奠定了基础。 - To meander channel , because the channel continuously moved , form duplicate fluvial sand bodies largely , and there are many area of non sandbodies or in fluvial sandbodies , there are some abandoned channel , all make the continuous of sandbodies poor upper the meander channel sandbodies , so remained oil is mainly distributed in sandbodies in fluvial channel , abandoned channel and non sandbodies area nearby
对曲流河砂体，由于平面上曲流河反复迁移和改造，以侧蚀和侧积方式形成了面积广阔的复合曲流河砂体，内部发育有许多尖灭区及河间砂体，边部及内还存在一定数量的废弃河道，从而使曲流河上半部侧向连通性变差，这类砂体中剩余油主要分布于河间砂、废弃河道部位及尖灭区附近。
